Okinawa Prefecture is the southernmost prefecture of Japan. It encompasses two thirds of the Ryukyu Islands in a chain over 1,000 kilometres long; the Ryukyu Islands extend southwest from Kagoshima Prefecture in Kyushu to Taiwan. Naha, Okinawa's capital, is located in the southern part of Okinawa Island. Although Okinawa Prefecture comprises just 0.6 percent of Japan's total land mass, about 75 percent of all United States military personnel stationed in Japan are assigned to installations in the prefecture. About 26,000 U. S. troops are based in the prefecture. The oldest evidence of human existence on the Ryukyu islands is from the Stone Age and was discovered in Naha and Yaeyama; some human bone fragments from the Paleolithic era were unearthed from a site in Naha, but the artifact was lost in transportation before it was examined to be Paleolithic or not. Japanese Jōmon influences are dominant on the Okinawa Islands, although clay vessels on the Sakishima Islands have a commonality with those in Taiwan.
The first mention of the word Ryukyu was written in the Book of Sui. Okinawa was the Japanese word identifying the islands, first seen in the biography of Jianzhen, written in 779. Agricultural societies begun in the 8th century developed until the 12th century. Since the islands are located at the eastern perimeter of the East China Sea close to Japan and South-East Asia, the Ryukyu Kingdom became a prosperous trading nation. During this period, many Gusukus, similar to castles, were constructed; the Ryukyu Kingdom entered into the Imperial Chinese tributary system under the Ming dynasty beginning in the 15th century, which established economic relations between the two nations. In 1609, the Shimazu clan, which controlled the region, now Kagoshima Prefecture, invaded the Ryukyu Kingdom; the Ryukyu Kingdom was obliged to agree to form a suzerain-vassal relationship with the Satsuma and the Tokugawa shogunate, while maintaining its previous role within the Chinese tributary system. The Satsuma clan earned considerable profits from trade with China during a period in which foreign trade was restricted by the shogunate.
Although Satsuma maintained strong influence over the islands, the Ryukyu Kingdom maintained a considerable degree of domestic political freedom for over two hundred years. Four years after the 1868 Meiji Restoration, the Japanese government, through military incursions annexed the kingdom and renamed it Ryukyu han. At the time, the Qing Empire asserted a nominal suzerainty over the islands of the Ryukyu Kingdom, since the Ryūkyū Kingdom was a member state of the Chinese tributary system. Ryukyu han became Okinawa Prefecture of Japan in 1879 though all other hans had become prefectures of Japan in 1872. In 1912, Okinawans first obtained the right to vote for representatives to the National Diet, established in 1890. Near the end of World War II, in 1945, the US Army and Marine Corps invaded Okinawa with 185,000 troops. A third of the civilian population died; the dead, of all nationalities, are commemorated at the Cornerstone of Peace. After the end of World War II, the Ryukyu independence movement developed, while Okinawa was under United States Military Government of the Ryukyu Islands administration for 27 years.
During this "trusteeship rule", the United States established numerous military bases on the Ryukyu islands. During the Korean War, B-29 Superfortresses flew bombing missions over Korea from Kadena Air Base on Okinawa; the military buildup on the island during the Cold War increased a division between local inhabitants and the American military. Under the 1952 Treaty of Mutual Cooperation and Security between the United States and Japan, the United States Forces Japan have maintained a large military presence. Since 1960, the U. S. and Japan have maintained an agreement that allows the U. S. to secretly bring nuclear weapons into Japanese ports. The Japanese tended to oppose the introduction of nuclear arms into Japanese territory by the government's assertion of Japan's non-nuclear policy and a statement of the Three Non-Nuclear Principles. Most of the weapons were alleged to be stored in ammunition bunkers at Kadena Air Base. Between 1954 and 1972, 19 different types of nuclear weapons were deployed in Okinawa, but with fewer than around 1,000 warheads at any one time.
Between 1965 and 1972, Okinawa was a key staging point for the United States in its military operations directed towards North Vietnam. Along with Guam, it presented a geographically strategic launch pad for covert bombing missions over Cambodia and Laos. Anti-Vietnam War sentiment became linked politically to the movement for reversion of Okinawa to Japan. In 1965, the US military bases, earlier viewed as paternal post war protection, were seen as aggressive; the Vietnam War highlighted the differences between the United States and Okinawa, but showed a commonality between the islands and mainland Japan. As controversy grew regarding the alleged placement of nuclear weapons on Okinawa, fears intensified over the escalation of the Vietnam War. Okinawa was perceived, by some inside Japan, as a potential target for China, should the communist government feel threatened by the United States. American military secrecy blocked any local reporting on what was occurring at bases such as Kadena Air Base.
As information leaked out, images of air strikes were published, the local population began to fear the potential for retaliation. Political leaders such as Oda Makoto
Fukushima Prefecture is a prefecture of Japan located in the Tōhoku region. The capital is the city of Fukushima; until the Meiji Restoration, the area of Fukushima prefecture was part of what was known as Mutsu Province. The Shirakawa Barrier and the Nakoso Barrier were built around the 5th century to protect'civilized Japan' from the'barbarians' to the north. Fukushima became a Province of Mutsu after the Taika Reforms were established in 646. In 718, the provinces of Iwase and Iwaki were created, but these areas reverted to Mutsu some time between 722 and 724; this region of Japan is known as Michinoku and Ōshū. The Fukushima Incident took place in the prefecture after Mishima Michitsune was appointed governor in 1882; the 2011 Tōhoku earthquake and tsunami and the resulting Fukushima Daiichi nuclear disaster caused significant damage to the prefecture but not limited to the eastern Hamadōri region. On Friday, March 11, 2011, 14:46 JST, a magnitude 9.0 earthquake occurred off the coast of Miyagi Prefecture.
Shindo measurements throughout the prefecture reached as high as 6-upper in isolated regions of Hama-dōri on the eastern coast and as low as a 2 in portions of the Aizu region in the western part of the prefecture. Fukushima City, located in Naka-dōri and the capital of Fukushima Prefecture, measured 6-lower. Following the earthquake there were isolated reports of major damage to structures, including the failure of Fujinuma Dam as well as damage from landslides; the earthquake triggered a massive tsunami that hit the eastern coast of the prefecture and caused widespread destruction and loss of life. In the two years following the earthquake, 1,817 residents of Fukushima Prefecture had either been confirmed dead or were missing as a result of the earthquake and tsunami. In the aftermath of the earthquake and the tsunami that followed, the outer housings of two of the six reactors at the Fukushima Daiichi Nuclear Power Plant in Ōkuma exploded followed by a partial meltdown and fires at three of the other units.
Many residents were evacuated to nearby localities due to the development of a large evacuation zone around the plant. Radiation levels near the plant peaked at 400 mSv/h after the earthquake and tsunami, due to damage sustained; this resulted in increased recorded radiation levels across Japan. On April 11, 2011, officials upgraded the disaster to a level 7 out of a possible 7, a rare occurrence not seen since the Chernobyl disaster in 1986. Several months officials announced that although the area nearest the melt down were still off limits, areas near the twenty kilometer radial safe zone could start seeing a return of the close to 47,000 residents, evacuated. Fukushima is both the southernmost prefecture of Tōhoku region and the prefecture of Tōhoku region, closest to Tokyo. With an area size of 13,784 km2 it is the third-largest prefecture of Japan, behind Hokkaido and Iwate Prefecture, it is divided by mountain ranges into three regions called Aizu, Nakadōri, Hamadōri. The coastal Hamadōri region lies on the Pacific Ocean and is the flattest and most temperate region, while the Nakadōri region is the agricultural heart of the prefecture and contains the capital, Fukushima City.
The mountainous Aizu region has scenic lakes, lush forests, snowy winters. As of April 1, 2012, 13% of the total land area of the prefecture was designated as Natural Parks, namely Bandai-Asahi, Nikkō, Oze National Parks. Thirteen cities are located in Fukushima Prefecture: These are the towns and villages in each district: The coastal region traditionally specializes in fishing and seafood industries, is notable for its electric and nuclear power-generating industry, while the upland regions are more focused on agriculture. Thanks to Fukushima's climate, various fruits are grown throughout the year; these include pears, cherries and apples. As of March 2011, the prefecture produced 8.7 % of cucumbers. Fukushima produces rice, that combined with pure water from mountain run-offs, is used to make sake; some sakes from the region are considered so tasteful that they are served to visiting royalty and world leaders by hosts. Lacquerware is another popular product from Fukushima. Dating back over four hundred years, the process of making lacquerware involves carving an object out of wood putting a lacquer on it and decorating it.
Objects made are dishes and writing materials. Legend has it that an ogress, once roamed the plain after whom it was named; the Adachigahara plain lies close to the city of Fukushima. Other stories, such as that of a large, red cow that carried wood, influenced toys and superstitions; the Aka-beko cow is a small, red papier-mâché cow on a bamboo or wooden frame, is believed to ease child birth, bring good health, help children grow up as strong as the cow. Another superstitious talisman of the region is self-righting dharma doll; these dolls are seen as bringers of good luck and prosperity because they stand right back up when knocked down. Miharu Koma are small, black or white toy horses painted with colorful designs. Depending upon their design, they may be believed to bring things like long life to the owner. Kokeshi dolls, while less symbolic, are a popular traditional craft, they are carved wooden dolls, with hand painted bodies. Kokeshi dolls are popular throughout many regions of Japan, but Fukushima is credited as their birthplace.
Sōma's Nomaoi Festival is held every summer. The Nomaoi Festival horse riders dressed in complete samurai attire can be seen racing, chasing wild
South Korea the Republic of Korea, is a country in East Asia, constituting the southern part of the Korean Peninsula and lying to the east of the Asian mainland. The name Korea is derived from Goguryeo, one of the great powers in East Asia during its time, ruling most of the Korean Peninsula, parts of the Russian Far East and Inner Mongolia, under Gwanggaeto the Great. South Korea has a predominantly mountainous terrain, it comprises an estimated 51.4 million residents distributed over 100,363 km2. Its capital and largest city is Seoul, with a population of around 10 million. Archaeology indicates that the Korean Peninsula was inhabited by early humans starting from the Lower Paleolithic period; the history of Korea begins with the foundation of Gojoseon in 2333 BCE by the mythic king Dangun, but no archaeological evidence and writing was found from this period. The Gija Joseon was purportedly founded in 11th century BCE, its existence and role has been controversial in the modern era; the written historical record on Gojoseon was first mentioned in Chinese records in the early 7th century BCE.
Following the unification of the Three Kingdoms of Korea under Unified Silla in CE 668, Korea was subsequently ruled by the Goryeo dynasty and the Joseon dynasty. It was annexed by the Empire of Japan in 1910. At the end of World War II, Korea was divided into Soviet and U. S. zones of occupations. A separate election was held in the U. S. zone in 1948 which led to the creation of the Republic of Korea, while the Democratic People's Republic of Korea was established in the Soviet zone. The United Nations at the time passed a resolution declaring the ROK to be the only lawful government in Korea; the Korean War began in June 1950. The war lasted three years and involved the U. S. China, the Soviet Union and several other nations; the border between the two nations remains the most fortified in the world. Under long-time military leader Park Chung-hee, the South Korean economy grew and the country was transformed into a G-20 major economy. Military rule ended in 1987, the country is now a presidential republic consisting of 17 administrative divisions.
South Korea is a developed country and a high-income economy, with a "very high" Human Development Index, ranking 22nd in the world. The country is considered a regional power and is the world's 11th largest economy by nominal GDP and the 12th largest by PPP as of 2010. South Korea is a global leader in the industrial and technological sectors, being the world's 5th largest exporter and 8th largest importer, its export-driven economy focuses production on electronics, ships, machinery and robotics. South Korea is a member of the ASEAN Plus mechanism, the United Nations, Uniting for Consensus, G20, the WTO and OECD and is a founding member of APEC and the East Asia Summit; the name Korea derives from the name Goryeo. The name Goryeo itself was first used by the ancient kingdom of Goguryeo in the 5th century as a shortened form of its name; the 10th-century kingdom of Goryeo succeeded Goguryeo, thus inherited its name, pronounced by the visiting Persian merchants as "Korea". The modern spelling of Korea first appeared in the late 17th century in the travel writings of the Dutch East India Company's Hendrick Hamel.
Despite the coexistence of the spellings Corea and Korea in 19th century publications, some Koreans believe that Imperial Japan, around the time of the Japanese occupation, intentionally standardised the spelling on Korea, making Japan appear first alphabetically. After Goryeo was replaced by Joseon in 1392, Joseon became the official name for the entire territory, though it was not universally accepted; the new official name has its origin in the ancient country of Gojoseon. In 1897, the Joseon dynasty changed the official name of the country from Joseon to Daehan Jeguk; the name Daehan, which means "Great Han" derives from Samhan, referring to the Three Kingdoms of Korea, not the ancient confederacies in the southern Korean Peninsula. However, the name Joseon was still used by Koreans to refer to their country, though it was no longer the official name. Under Japanese rule, the two names Han and Joseon coexisted. There were several groups who fought for independence, the most notable being the Provisional Government of the Republic of Korea.
Following the surrender of Japan, in 1945, the Republic of Korea was adopted as the legal English name for the new country. Since the government only controlled the southern part of the Korean Peninsula, the informal term South Korea was coined, becoming common in the Western world. While South Koreans use Han to refer to the entire country, North Koreans and ethnic Koreans living in China and Japan use the term Joseon as the name of the country; the Korean name "Daehan Minguk" is sometimes used by South Koreans as a metonym to refer to the Korean ethnicity as a whole, rather than just the South Korean state. The history of Korea begins with the founding of Joseon in 2333 BCE by Dangun, according to Korea's foundation mythology. Gojoseon expanded until it controlled parts of Manchuria. Gija Joseon was purportedly founded in the 12th century BC, but its existence and role have been controversial in the modern era. In 108 BCE, the Han dynasty defeated Wiman Joseon and installed four commanderies in the n
The eudicots, Eudicotidae or eudicotyledons are a clade of flowering plants, called tricolpates or non-magnoliid dicots by previous authors. The botanical terms were introduced in 1991 by evolutionary botanist James A. Doyle and paleobotanist Carol L. Hotton to emphasize the evolutionary divergence of tricolpate dicots from earlier, less specialized, dicots; the close relationships among flowering plants with tricolpate pollen grains was seen in morphological studies of shared derived characters. These plants have a distinct trait in their pollen grains of exhibiting three colpi or grooves paralleling the polar axis. Molecular evidence confirmed the genetic basis for the evolutionary relationships among flowering plants with tricolpate pollen grains and dicotyledonous traits; the term means "true dicotyledons", as it contains the majority of plants that have been considered dicots and have characteristics of the dicots. The term "eudicots" has subsequently been adopted in botany to refer to one of the two largest clades of angiosperms, monocots being the other.
The remaining angiosperms include magnoliids and what are sometimes referred to as basal angiosperms or paleodicots, but these terms have not been or adopted, as they do not refer to a monophyletic group. The other name for the eudicots is tricolpates, a name which refers to the grooved structure of the pollen. Members of the group have tricolpate pollen; these pollens have three or more pores set in furrows called colpi. In contrast, most of the other seed plants produce monosulcate pollen, with a single pore set in a differently oriented groove called the sulcus; the name "tricolpates" is preferred by some botanists to avoid confusion with the dicots, a nonmonophyletic group. Numerous familiar plants are eudicots, including many common food plants and ornamentals; some common and familiar eudicots include members of the sunflower family such as the common dandelion, the forget-me-not and other members of its family, buttercup and macadamia. Most leafy trees of midlatitudes belong to eudicots, with notable exceptions being magnolias and tulip trees which belong to magnoliids, Ginkgo biloba, not an angiosperm.
The name "eudicots" is used in the APG system, of 1998, APG II system, of 2003, for classification of angiosperms. It is applied to a monophyletic group, which includes most of the dicots. "Tricolpate" is a synonym for the "Eudicot" monophyletic group, the "true dicotyledons". The number of pollen grain furrows or pores helps classify the flowering plants, with eudicots having three colpi, other groups having one sulcus. Pollen apertures are any modification of the wall of the pollen grain; these modifications include thinning and pores, they serve as an exit for the pollen contents and allow shrinking and swelling of the grain caused by changes in moisture content. The elongated apertures/ furrows in the pollen grain are called colpi, along with pores, are a chief criterion for identifying the pollen classes; the eudicots can be divided into two groups: the basal eudicots and the core eudicots. Basal eudicot is an informal name for a paraphyletic group; the core eudicots are a monophyletic group.
A 2010 study suggested the core eudicots can be divided into two clades, Gunnerales and a clade called "Pentapetalae", comprising all the remaining core eudicots. The Pentapetalae can be divided into three clades: Dilleniales superrosids consisting of Saxifragales and rosids superasterids consisting of Santalales, Berberidopsidales and asteridsThis division of the eudicots is shown in the following cladogram: The following is a more detailed breakdown according to APG IV, showing within each clade and orders: clade Eudicots order Ranunculales order Proteales order Trochodendrales order Buxales clade Core eudicots order Gunnerales order Dilleniales clade Superrosids order Saxifragales clade Rosids order Vitales clade Fabids order Fabales order Rosales order Fagales order Cucurbitales order Oxalidales order Malpighiales order Celastrales order Zygophyllales clade Malvids order Geraniales order Myrtales order Crossosomatales order Picramniales order Malvales order Brassicales order Huerteales order Sapindales clade Superasterids order Berberidopsidales order Santalales order Caryophyllales clade Asterids order Cornales order Ericales clade Campanulids order Aquifoliales order Asterales order Escalloniales order Bruniales order Apiales order Dipsacales order Paracryphiales clade Lamiids order Solanales order Lamiales order Vahliales order Gentianales order Boraginales order Garryales order Metteniusales order Icacinales Eudicots at the Encyclopedia of Life Eudicots, Tree of Life Web Project Dicots Plant Life Forms
Japan is an island country in East Asia. Located in the Pacific Ocean, it lies off the eastern coast of the Asian continent and stretches from the Sea of Okhotsk in the north to the East China Sea and the Philippine Sea in the south; the kanji that make up Japan's name mean "sun origin", it is called the "Land of the Rising Sun". Japan is a stratovolcanic archipelago consisting of about 6,852 islands; the four largest are Honshu, Hokkaido and Shikoku, which make up about ninety-seven percent of Japan's land area and are referred to as home islands. The country is divided into 47 prefectures in eight regions, with Hokkaido being the northernmost prefecture and Okinawa being the southernmost one; the population of 127 million is the world's tenth largest. 90.7 % of people live in cities. About 13.8 million people live in the capital of Japan. The Greater Tokyo Area is the most populous metropolitan area in the world with over 38 million people. Archaeological research indicates; the first written mention of Japan is in Chinese history texts from the 1st century AD.
Influence from other regions China, followed by periods of isolation from Western Europe, has characterized Japan's history. From the 12th century until 1868, Japan was ruled by successive feudal military shōguns who ruled in the name of the Emperor. Japan entered into a long period of isolation in the early 17th century, ended in 1853 when a United States fleet pressured Japan to open to the West. After nearly two decades of internal conflict and insurrection, the Imperial Court regained its political power in 1868 through the help of several clans from Chōshū and Satsuma – and the Empire of Japan was established. In the late 19th and early 20th centuries, victories in the First Sino-Japanese War, the Russo-Japanese War and World War I allowed Japan to expand its empire during a period of increasing militarism; the Second Sino-Japanese War of 1937 expanded into part of World War II in 1941, which came to an end in 1945 following the Japanese surrender. Since adopting its revised constitution on May 3, 1947, during the occupation led by SCAP, the sovereign state of Japan has maintained a unitary parliamentary constitutional monarchy with an Emperor and an elected legislature called the National Diet.
Japan is a member of the ASEAN Plus mechanism, UN, the OECD, the G7, the G8, the G20, is considered a great power. Its economy is the world's third-largest by nominal GDP and the fourth-largest by purchasing power parity, it is the world's fourth-largest exporter and fourth-largest importer. Japan benefits from a skilled and educated workforce. Although it has renounced its right to declare war, Japan maintains a modern military with the world's eighth-largest military budget, used for self-defense and peacekeeping roles. Japan is a developed country with a high standard of living and Human Development Index, its population enjoys the highest life expectancy and third lowest infant mortality rate in the world, but is experiencing issues due to an aging population and low birthrate. Japan is renowned for its historical and extensive cinema, influential music industry, video gaming, rich cuisine and its major contributions to science and modern technology; the Japanese word for Japan is 日本, pronounced Nihon or Nippon and means "the origin of the sun".
The character nichi means "sun" or "day". The compound therefore means "origin of the sun" and is the source of the popular Western epithet "Land of the Rising Sun"; the earliest record of the name Nihon appears in the Chinese historical records of the Tang dynasty, the Old Book of Tang. At the end of the seventh century, a delegation from Japan requested that Nihon be used as the name of their country; this name may have its origin in a letter sent in 607 and recorded in the official history of the Sui dynasty. Prince Shōtoku, the Regent of Japan, sent a mission to China with a letter in which he called himself "the Emperor of the Land where the Sun rises"; the message said: "Here, I, the emperor of the country where the sun rises, send a letter to the emperor of the country where the sun sets. How are you". Prior to the adoption of Nihon, other terms such as Yamato and Wakoku were used; the term Wa is a homophone of Wo 倭, used by the Chinese as a designation for the Japanese as early as the third century Three Kingdoms period.
Another form of Wa, Wei in Chinese) was used for an early state in Japan called Nakoku during the Han dynasty. However, the Japanese disliked some connotation of Wa 倭, it was therefore replaced with the substitute character Wa, meaning "togetherness, harmony"; the English word Japan derives from the historical Chinese pronunciation of 日本. The Old Mandarin or early Wu Chinese pronunciation of Japan was recorded by Marco Polo as Cipangu. In modern Shanghainese, a Wu dialect, the pronunciation of characters 日本; the old Malay word for Japan, Japun or Japang, was borrowed from a southern coastal Chinese dialect Fukienese or Ningpo – and this Malay word was encountered by Portuguese traders in Southeast Asia in the 16th century. These Early Portuguese traders brought the word
The pear tree and shrub are a species of genus Pyrus, in the family Rosaceae, bearing the pomaceous fruit of the same name. Several species of pear are valued for their edible fruit and juices while others are cultivated as trees; the word pear is from Germanic pera as a loanword of Vulgar Latin pira, the plural of pirum, akin to Greek apios, of Semitic origin, meaning "fruit". The adjective pyriform or piriform means pear-shaped; the pear is native to coastal and mildly temperate regions of the Old World, from western Europe and north Africa east right across Asia. It is a medium-sized tree, reaching 10–17 metres tall with a tall, narrow crown; the leaves are alternately arranged, simple, 2–12 centimetres long, glossy green on some species, densely silvery-hairy in some others. Most pears are deciduous. Most are cold-hardy, withstanding temperatures between −25 °C and −40 °C in winter, except for the evergreen species, which only tolerate temperatures down to about −15 °C; the flowers are white tinted yellow or pink, 2–4 centimetres diameter, have five petals.
Like that of the related apple, the pear fruit is a pome, in most wild species 1–4 centimetres diameter, but in some cultivated forms up to 18 centimetres long and 8 centimetres broad. The fruit is composed of the receptacle or upper end of the flower-stalk dilated. Enclosed within its cellular flesh is the true fruit: five'cartilaginous' carpels, known colloquially as the "core". From the upper rim of the receptacle are given off the five sepals, the five petals, the numerous stamens. Pears and apples cannot always be distinguished by the form of the fruit. One major difference is. Pear cultivation in cool temperate climates extends to the remotest antiquity, there is evidence of its use as a food since prehistoric times. Many traces of it have been found in prehistoric pile dwellings around Lake Zurich; the word “pear”, or its equivalent, occurs in all the Celtic languages, while in Slavic and other dialects, differing appellations, still referring to the same thing, are found—a diversity and multiplicity of nomenclature which led Alphonse Pyramus de Candolle to infer a ancient cultivation of the tree from the shores of the Caspian to those of the Atlantic.
The pear was cultivated by the Romans, who ate the fruits raw or cooked, just like apples. Pliny's Natural History noted three dozen varieties; the Roman cookbook De re coquinaria has a recipe for a spiced, stewed-pear patina, or soufflé. A certain race of pears, with white down on the undersurface of their leaves, is supposed to have originated from P. nivalis, their fruit is chiefly used in France in the manufacture of perry. Other small-fruited pears, distinguished by their early ripening and apple-like fruit, may be referred to as P. cordata, a species found wild in western France and southwestern England. Pears have been cultivated in China for 3000 years; the genus is thought to have originated in present-day Western China in the foothills of the Tian Shan, a mountain range of Central Asia, to have spread to the north and south along mountain chains, evolving into a diverse group of over 20 recognized primary species. The enormous number of varieties of the cultivated European pear, are without doubt derived from one or two wild subspecies distributed throughout Europe, sometimes forming part of the natural vegetation of the forests.
Court accounts of Henry III of England record pears shipped from La Rochelle-Normande and presented to the King by the Sheriffs of the City of London. The French names of pears grown in English medieval gardens suggest that their reputation, at the least, was French. Asian species with medium to large edible fruit include P. pyrifolia, P. ussuriensis, P. × bretschneideri, P. × sinkiangensis, P. pashia. Other small-fruited species are used as rootstocks for the cultivated forms. According to Pear Bureau Northwest, about 3000 known varieties of pears are grown worldwide; the pear is propagated by grafting a selected variety onto a rootstock, which may be of a pear variety or quince. Quince rootstocks produce smaller trees, desirable in commercial orchards or domestic gardens. For new varieties the flowers can be cross-bred to combine desirable traits; the fruit of the pear is produced on spurs. Three species account for the vast majority of edible fruit production, the European pear Pyrus communis subsp.
Communis cultivated in Europe and North America, the Chinese white pear Pyrus ×bretschneideri, the Nashi pear Pyrus pyrifolia, both grown in eastern Asia. There are thousands of cultivars of these three species. A species grown in western China, P. sinkiangensis, P. pashia, grown in southern China and south Asia, are produced to a lesser degree. Other species are used as ornamental trees. Pear wood is close-grained a
East Asia is the eastern subregion of Asia, defined in either geographical or ethno-cultural terms. China, Japan and Vietnam belong to the East Asian cultural sphere. Geographically and geopolitically, the region includes China, Hong Kong, Taiwan, Mongolia, North Korea, South Korea; the region was the cradle of various ancient civilizations such as ancient China, ancient Japan, ancient Korea, the Mongol Empire. East Asia was one of the cradles of world civilization, with China, an ancient East Asian civilization being one of the earliest cradles of civilization in human history. For thousands of years, China influenced East Asia as it was principally the leading civilization in the region exerting its enormous prestige and influence on its neighbors. Societies in East Asia have been part of the Chinese cultural sphere, East Asian vocabulary and scripts are derived from Classical Chinese and Chinese script; the Chinese calendar preserves traditional East Asian culture and serves as the root to which many other East Asian calendars are derived from.
Major religions in East Asia include Buddhism and Neo-Confucianism, Ancestral worship, Chinese folk religion in Greater China and Shintoism in Japan, Christianity and Sindoism in Korea. Shamanism is prevalent among Mongols and other indigenous populations of northern East Asia such as the Manchus. East Asians comprise around 1.6 billion people, making up about 38% of the population in Continental Asia and 22% of the global population. The region is home to major world metropolises such as Beijing, Hong Kong, Shanghai and Tokyo. Although the coastal and riparian areas of the region form one of the world's most populated places, the population in Mongolia and Western China, both landlocked areas, is sparsely distributed, with Mongolia having the lowest population density of any sovereign state; the overall population density of the region is 133 inhabitants per square kilometre, about three times the world average of 45/km2. In comparison with the profound influence of the Ancient Greeks and Romans on Europe and the Western World, China would possess an advanced civilization nearly half a millennia before Japan and Korea.
As Chinese civilization existed for about 1500 years before other East Asian civilizations emerged into history, Imperial China would exert much of its cultural, economic and political muscle onto its neighbors. Succeeding Chinese dynasties exerted enormous influence across East Asia culturally, economically and militarily for over two millennia. Imperial China's cultural preeminence not only led the country to become East Asia's first literate nation in the entire region, it supplied Japan and Korea with Chinese loanwords and linguistic influences rooted in their writing systems. In addition, the Chinese Han dynasty hosted the largest unified population in East Asia, the most literate and urbanized as well as being the most technologically and culturally advanced civilization in the region. Cultural and religious interaction between the Chinese and other regional East Asian dynasties and kingdoms occurred. China's impact and influence on Korea began with the Han dynasty's northeastern expansion in 108 BC when the Han Chinese conquered the northern part of the Korean peninsula and established a province called Lelang.
Chinese influence would soon take root in Korea through the inclusion of the Chinese writing system, monetary system, rice culture, Confucian political institutions. Jōmon society in ancient Japan incorporated wet-rice cultivation and metallurgy through its contact with Korea. Vietnamese society was impacted by Chinese influence, the northern part of Vietnam was occupied by Chinese empires and states for all of the period from 111 BC to 938 AD. In addition to administration, making Chinese the language of administration, the long period of Chinese domination introduced Chinese techniques of dike construction, rice cultivation, animal husbandry. Chinese culture, having been established among the elite mandarin class, remained the dominant current among that elite for most of the next 1,000 years until the loss of independence under French Indochina; this cultural affiliation to China remained true when militarily defending Vietnam against attempted invasion, such as against the Mongol Kublai Khan.
The only significant exceptions to this were the 7 years of the anti-Chinese Hồ dynasty which banned the use of Chinese, but after the expulsion of the Ming the rise in vernacular chữ nôm literature.
