Japanese yen
–
The yen is the official currency of Japan. It is the third most traded currency in the exchange market after the United States dollar. It is also used as a reserve currency after the U. S. dollar, the euro. Before the Meiji Restoration, Japans feudal fiefs all issued their own money, hansatsu, in an array of incompatible denominations. The New Currency Act of 1871 did away with these and established the yen, the former han became prefectures and their mints private chartered banks, which initially retained the right to print money. To bring an end to this situation the Bank of Japan was founded in 1882, following World War II the yen lost much of its prewar value. To stabilize the Japanese economy the exchange rate of the yen was fixed at ¥360 per $1 as part of the Bretton Woods system, when that system was abandoned in 1971, the yen became undervalued and was allowed to float. The yen had appreciated to a peak of ¥271 per $1 in 1973, then underwent periods of depreciation and appreciation due to the 1973 oil crisis, arriving at a value of ¥227 per $1 by 1980. Since 1973, the Japanese government has maintained a policy of intervention. The Japanese government focuses on an export market, and tries to ensure a low yen value through a trade surplus. Since that time, however, the yen has greatly decreased in value, the Bank of Japan maintains a policy of zero to near-zero interest rates and the Japanese government has an extreme anti-inflation policy. Yen derives from the Japanese word 圓, which is cognate with the Chinese yuan, originally, the Chinese had traded silver in mass called sycees and when Spanish and Mexican silver coins arrived, the Chinese called them silver rounds for their circular shapes. The coins and the name appeared in Japan. While the Chinese eventually replaced 圓 with 元, the Japanese continued to use the same word, the spelling and pronunciation yen is standard in English. This is because mainly English speakers who visited Japan at the end of the Edo period to the early Meiji period spelled words this way, ゑん /wen/ in historical kana orthography. In the 16th century, Japanese /e/ and /we/ both had been pronounced and Portuguese missionaries had spelled them ye, some time thereafter, by the middle of the 18th century, /e/ and /we/ came to be pronounced as in modern Japanese, although some regions retain the pronunciation. In the early Meiji era, James Curtis Hepburn, following Medhurst, spelled all es as ye in his A Japanese and that was the first full-scale Japanese-English/English-Japanese dictionary, which had a strong influence on Westerners in Japan and probably prompted the spelling yen. Hepburn revised most of yes to e in the 3rd edition in order to mirror the contemporary pronunciation and this was probably already fixed and has remained so ever since

Copper
–
Copper is a chemical element with symbol Cu and atomic number 29. It is a soft, malleable, and ductile metal with high thermal and electrical conductivity. A freshly exposed surface of copper has a reddish-orange color. Copper is one of the few metals that occur in nature in directly usable metallic form as opposed to needing extraction from an ore and this led to very early human use, from c.8000 BC. Copper used in buildings, usually for roofing, oxidizes to form a green verdigris, Copper is sometimes used in decorative art, both in its elemental metal form and in compounds as pigments. Copper compounds are used as agents, fungicides, and wood preservatives. Copper is essential to all living organisms as a trace dietary mineral because it is a key constituent of the enzyme complex cytochrome c oxidase. In molluscs and crustaceans, copper is a constituent of the blood pigment hemocyanin, replaced by the hemoglobin in fish. In humans, copper is found mainly in the liver, muscle, the adult body contains between 1.4 and 2.1 mg of copper per kilogram of body weight. The filled d-shells in these elements contribute little to interatomic interactions, unlike metals with incomplete d-shells, metallic bonds in copper are lacking a covalent character and are relatively weak. This observation explains the low hardness and high ductility of single crystals of copper, at the macroscopic scale, introduction of extended defects to the crystal lattice, such as grain boundaries, hinders flow of the material under applied stress, thereby increasing its hardness. For this reason, copper is supplied in a fine-grained polycrystalline form. The softness of copper partly explains its high conductivity and high thermal conductivity. The maximum permissible current density of copper in open air is approximately 3. 1×106 A/m2 of cross-sectional area, Copper is one of a few metallic elements with a natural color other than gray or silver. Pure copper is orange-red and acquires a reddish tarnish when exposed to air, as with other metals, if copper is put in contact with another metal, galvanic corrosion will occur. A green layer of verdigris can often be seen on old structures, such as the roofing of many older buildings. Copper tarnishes when exposed to sulfur compounds, with which it reacts to form various copper sulfides. There are 29 isotopes of copper, 63Cu and 65Cu are stable, with 63Cu comprising approximately 69% of naturally occurring copper, both have a spin of 3⁄2
3.
Zinc
–
Zinc is a chemical element with the symbol Zn and atomic number 30. It is the first element in group 12 of the periodic table, in some respects zinc is chemically similar to magnesium, both elements exhibit only one normal oxidation state, and the Zn2+ and Mg2+ ions are of similar size. Zinc is the 24th most abundant element in Earths crust and has five stable isotopes, the most common zinc ore is sphalerite, a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States, Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity. Zinc metal was not produced on a large scale until the 12th century in India and was unknown to Europe until the end of the 16th century, the mines of Rajasthan have given definite evidence of zinc production going back to the 6th century BC. To date, the oldest evidence of pure zinc comes from Zawar, in Rajasthan, alchemists burned zinc in air to form what they called philosophers wool or white snow. The element was named by the alchemist Paracelsus after the German word Zinke. German chemist Andreas Sigismund Marggraf is credited with discovering pure metallic zinc in 1746, work by Luigi Galvani and Alessandro Volta uncovered the electrochemical properties of zinc by 1800. Corrosion-resistant zinc plating of iron is the application for zinc. Other applications are in batteries, small non-structural castings. A variety of compounds are commonly used, such as zinc carbonate and zinc gluconate, zinc chloride, zinc pyrithione, zinc sulfide. Zinc is an essential mineral perceived by the public today as being of exceptional biologic and public health importance, Zinc deficiency affects about two billion people in the developing world and is associated with many diseases. In children, deficiency causes growth retardation, delayed sexual maturation, infection susceptibility, enzymes with a zinc atom in the reactive center are widespread in biochemistry, such as alcohol dehydrogenase in humans. Consumption of excess zinc can cause ataxia, lethargy and copper deficiency, Zinc is a bluish-white, lustrous, diamagnetic metal, though most common commercial grades of the metal have a dull finish.6 pm. The metal is hard and brittle at most temperatures but becomes malleable between 100 and 150 °C, above 210 °C, the metal becomes brittle again and can be pulverized by beating. Zinc is a conductor of electricity. For a metal, zinc has relatively low melting and boiling points, the melting point is the lowest of all the transition metals aside from mercury and cadmium. Many alloys contain zinc, including brass, Other metals long known to form binary alloys with zinc are aluminium, antimony, bismuth, gold, iron, lead, mercury, silver, tin, magnesium, cobalt, nickel, tellurium, and sodium
4.
Tin
–
Tin is a chemical element with symbol Sn and atomic number 50. It is a metal in group 14 of the periodic table. It is obtained chiefly from the mineral cassiterite, which contains tin dioxide, Tin shows a chemical similarity to both of its neighbors in group 14, germanium and lead, and has two main oxidation states, +2 and the slightly more stable +4. Tin is the 49th most abundant element and has, with 10 stable isotopes, metallic tin is not easily oxidized in air. The first alloy used on a scale was bronze, made of tin and copper. After 600 BC, pure metallic tin was produced, pewter, which is an alloy of 85–90% tin with the remainder commonly consisting of copper, antimony, and lead, was used for flatware from the Bronze Age until the 20th century. In modern times, tin is used in alloys, most notably tin/lead soft solders. Another large application for tin is corrosion-resistant tin plating of steel, inorganic tin compounds are rather non-toxic. Because of its low toxicity, tin-plated metal was used for packaging as tin cans. However, overexposure to tin may cause problems with metabolizing essential trace elements such as copper and zinc, Tin is a soft, malleable, ductile and highly crystalline silvery-white metal. When a bar of tin is bent, a sound known as the tin cry can be heard from the twinning of the crystals. Tin melts at the low temperature of about 232 °C, the lowest in group 14, the melting point is further lowered to 177.3 °C for 11 nm particles. β-tin, which is stable at and above room temperature, is malleable, in contrast, α-tin, which is stable below 13.2 °C, is brittle. α-tin has a cubic crystal structure, similar to diamond. α-tin has no properties at all because its atoms form a covalent structure in which electrons cannot move freely. It is a dull-gray powdery material with no common uses other than a few specialized semiconductor applications and these two allotropes, α-tin and β-tin, are more commonly known as gray tin and white tin, respectively. Two more allotropes, γ and σ, exist at temperatures above 161 °C, in cold conditions, β-tin tends to transform spontaneously into α-tin, a phenomenon known as tin pest. Commercial grades of tin resist transformation because of the effect of the small amounts of bismuth, antimony, lead

Laurus nobilis
–
Laurus nobilis is an aromatic evergreen tree or large shrub with green, glabrous leaves, in the flowering plant family Lauraceae. It is native to the Mediterranean region and is used as bay leaf for seasoning in cooking and its common names include bay laurel, sweet bay, bay, true laurel, Grecian laurel, laurel tree or simply laurel. Laurus nobilis figures prominently in classical Greek, Roman, and Biblical culture, the laurel is an evergreen shrub or small tree, variable in size and sometimes reaching 7–18 metres tall. The genus Laurus includes four accepted species, whose diagnostic key characters often overlap, the bay laurel is dioecious, with male and female flowers on separate plants. Each flower is pale yellow-green, about 1 cm diameter, the leaves are glabrous, 6–12 cm long and 2–4 cm broad, with an entire margin. On some leaves the margin undulates, the fruit is a small, shiny black berry-like drupe about 1 cm long that contains one seed. A recent study found considerable genetic diversity within L. nobilis, Laurus nobilis is a widespread relic of the laurel forests that originally covered much of the Mediterranean Basin when the climate of the region was more humid. With the drying of the Mediterranean during the Pliocene era, the forests gradually retreated. The most abundant component found in essential oil is 1, 8-cineole. Both essential and fatty oils are present in the fruit, the fruit is pressed and water-extracted to obtain these products. The fruit contains up to 30% fatty oils and about 1% essential oils, the plant is the source of several popular herbs and one spice used in a wide variety of recipes, particularly among Mediterranean cuisines. Most commonly, the leaves are added whole to Italian pasta sauces. They are typically removed from dishes before serving, unless used as a simple garnish, whole bay leaves have a long shelf life of about one year, under normal temperature and humidity. Whole bay leaves are used almost exclusively as flavor agents during the preparation stage. Ground bay leaves, however, can be ingested safely and are used in soups and stocks. Dried laurel berries and pressed leaf oil can both be used as robust spices, and the wood can be burnt for strong smoke flavoring, aqueous extracts of bay laurel can also be used as astringents and even as a reasonable salve for open wounds. In massage therapy, the oil of bay laurel is reputed to alleviate arthritis and rheumatism, while in aromatherapy, it is used to treat earaches. A traditional folk remedy for rashes caused by poison ivy, poison oak, the chemical compound lauroside B isolated from Laurus nobilis is an inhibitor of human melanoma cell proliferation at high concentrations in-vitro

Japan
–
Japan is a sovereign island nation in Eastern Asia. Located in the Pacific Ocean, it lies off the eastern coast of the Asia Mainland and stretches from the Sea of Okhotsk in the north to the East China Sea, the kanji that make up Japans name mean sun origin. 日 can be read as ni and means sun while 本 can be read as hon, or pon, Japan is often referred to by the famous epithet Land of the Rising Sun in reference to its Japanese name. Japan is an archipelago consisting of about 6,852 islands. The four largest are Honshu, Hokkaido, Kyushu and Shikoku, the country is divided into 47 prefectures in eight regions. Hokkaido being the northernmost prefecture and Okinawa being the southernmost one, the population of 127 million is the worlds tenth largest. Japanese people make up 98. 5% of Japans total population, approximately 9.1 million people live in the city of Tokyo, the capital of Japan. Archaeological research indicates that Japan was inhabited as early as the Upper Paleolithic period, the first written mention of Japan is in Chinese history texts from the 1st century AD. Influence from other regions, mainly China, followed by periods of isolation, from the 12th century until 1868, Japan was ruled by successive feudal military shoguns who ruled in the name of the Emperor. Japan entered into a period of isolation in the early 17th century. 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 bombings of Hiroshima and Nagasaki. Japan is a member of the UN, the OECD, the G7, the G8, the country has the worlds third-largest economy by nominal GDP and the worlds fourth-largest economy by purchasing power parity. It is also the worlds fourth-largest exporter and fourth-largest importer, although Japan has officially renounced its right to declare war, it maintains a modern military with the worlds eighth-largest military budget, used for self-defense and peacekeeping roles. Japan is a country with a very high standard of living. Its population enjoys the highest life expectancy and the third lowest infant mortality rate in the world, in ancient China, Japan was called Wo 倭. It was mentioned in the third century Chinese historical text Records of the Three Kingdoms in the section for the Wei kingdom, Wa became disliked because it has the connotation of the character 矮, meaning dwarf. The 倭 kanji has been replaced with the homophone Wa, meaning harmony, the Japanese word for Japan is 日本, which is pronounced Nippon or Nihon and literally means the origin of the sun. The earliest record of the name Nihon appears in the Chinese historical records of the Tang dynasty, at the start of the seventh century, a delegation from Japan introduced their country as Nihon

Buddhism
–
Buddhism is a religion and dharma that encompasses a variety of traditions, beliefs and spiritual practices largely based on teachings attributed to the Buddha. Buddhism originated in India sometime between the 6th and 4th centuries BCE, from where it spread through much of Asia, two major extant branches of Buddhism are generally recognized by scholars, Theravada and Mahayana. Buddhism is the worlds fourth-largest religion, with over 500 million followers or 7% of the global population, Buddhist schools vary on the exact nature of the path to liberation, the importance and canonicity of various teachings and scriptures, and especially their respective practices. In Theravada the ultimate goal is the attainment of the state of Nirvana, achieved by practicing the Noble Eightfold Path, thus escaping what is seen as a cycle of suffering. Theravada has a following in Sri Lanka and Southeast Asia. Mahayana, which includes the traditions of Pure Land, Zen, Nichiren Buddhism, Shingon, rather than Nirvana, Mahayana instead aspires to Buddhahood via the bodhisattva path, a state wherein one remains in the cycle of rebirth to help other beings reach awakening. Vajrayana, a body of teachings attributed to Indian siddhas, may be viewed as a branch or merely a part of Mahayana. Tibetan Buddhism, which preserves the Vajrayana teachings of eighth century India, is practiced in regions surrounding the Himalayas, Tibetan Buddhism aspires to Buddhahood or rainbow body. Buddhism is an Indian religion attributed to the teachings of Buddha, the details of Buddhas life are mentioned in many early Buddhist texts but are inconsistent, his social background and life details are difficult to prove, the precise dates uncertain. Some hagiographic legends state that his father was a king named Suddhodana, his mother queen Maya, and he was born in Lumbini gardens. Some of the stories about Buddha, his life, his teachings, Buddha was moved by the innate suffering of humanity. He meditated on this alone for a period of time, in various ways including asceticism, on the nature of suffering. He famously sat in meditation under a Ficus religiosa tree now called the Bodhi Tree in the town of Bodh Gaya in Gangetic plains region of South Asia. He reached enlightenment, discovering what Buddhists call the Middle Way, as an enlightened being, he attracted followers and founded a Sangha. Now, as the Buddha, he spent the rest of his teaching the Dharma he had discovered. Dukkha is a concept of Buddhism and part of its Four Noble Truths doctrine. It can be translated as incapable of satisfying, the unsatisfactory nature, the Four Truths express the basic orientation of Buddhism, we crave and cling to impermanent states and things, which is dukkha, incapable of satisfying and painful. This keeps us caught in saṃsāra, the cycle of repeated rebirth, dukkha

Kanji
–
Kanji, or kanji, are the adopted logographic Chinese characters that are used in the modern Japanese writing system along with hiragana and katakana. The Japanese term kanji for the Chinese characters literally means Han characters and is using the same characters as the Chinese word hànzì. Chinese characters first came to Japan on official seals, letters, swords, coins, mirrors, the earliest known instance of such an import was the King of Na gold seal given by Emperor Guangwu of Han to a Yamato emissary in 57 AD. Chinese coins from the first century AD have been found in Yayoi-period archaeological sites, however, the Japanese of that era probably had no comprehension of the script, and would remain illiterate until the fifth century AD. The earliest Japanese documents were written by bilingual Chinese or Korean officials employed at the Yamato court. For example, the correspondence from King Bu of Wa to Emperor Shun of Liu Song in 478 has been praised for its skillful use of allusion. Later, groups of people called fuhito were organized under the monarch to read, during the reign of Empress Suiko, the Yamato court began sending full-scale diplomatic missions to China, which resulted in a large increase in Chinese literacy at the Japanese court. The Japanese language had no form at the time Chinese characters were introduced. Chinese characters also came to be used to write Japanese words, around 650 CE, a writing system called manyōgana evolved that used a number of Chinese characters for their sound, rather than for their meaning. Manyōgana written in cursive style evolved into hiragana, or onna-de, that is, ladies hand, major works of Heian-era literature by women were written in hiragana. Katakana emerged via a path, monastery students simplified manyōgana to a single constituent element. Thus the two writing systems, hiragana and katakana, referred to collectively as kana, are descended from kanji. Katakana are mostly used for representing onomatopoeia, non-Japanese loanwords, the names of plants and animals, and for emphasis on certain words. In 1946, following World War II and under the Allied Occupation of Japan and this was done with the goal of facilitating learning for children and simplifying kanji use in literature and periodicals. The number of characters in circulation was reduced, and formal lists of characters to be learned during each grade of school were established, some characters were given simplified glyphs, called shinjitai. Many variant forms of characters and obscure alternatives for common characters were officially discouraged and these are simply guidelines, so many characters outside these standards are still widely known and commonly used, these are known as hyōgaiji. The kyōiku kanji are 1,006 characters that Japanese children learn in elementary school, originally the list only contained 881 characters. This was expanded to 996 characters in 1977 and it was not until 1982 the list was expanded to its current size

Hirohito
–
Emperor Shōwa was the 124th Emperor of Japan according to the traditional order of succession, reigning from December 25,1926, until his death on January 7,1989. He was succeeded by his eldest son, Akihito, upon his death, although better known outside Japan by his personal name Hirohito, in Japan, he is now referred to primarily by his posthumous name Emperor Shōwa. The word Shōwa is the name of the era that corresponded with the Emperors reign, the name Hirohito means abundant benevolence. He was the head of state under the Constitution of the Empire of Japan during Japans imperial expansion, militarization, born in Tokyos Aoyama Palace, Hirohito was the first son of Crown Prince Yoshihito and Crown Princess Sadako. He was the grandson of Emperor Meiji and Yanagihara Naruko and his childhood title was Prince Michi. At the age of 3, Hirohito and his brother Chichibu were returned to court when Kawamura died – first to the mansion in Numazu, Shizuoka. In 1908, he began studies at the Gakushūin. When his grandfather, Emperor Meiji, died on July 30,1912, Hirohitos father, Yoshihito, assumed the throne, in 1914, he was promoted to the ranks of lieutenant in the army and sub-lieutenant in the navy, then to captain and lieutenant in 1916. He was formally proclaimed Crown Prince and heir apparent on November 2,1916, Hirohito attended Gakushūin Peers School from 1908 to 1914 and then a special institute for the crown prince from 1914 to 1921. In 1920, Hirohito was promoted to the rank of Major in the army, in 1921, Hirohito took a six-month tour of Western Europe, including the United Kingdom, France, Italy, the Netherlands, and Belgium. After his return to Japan, he became Regent of Japan on November 29,1921, in 1923, he was promoted to the rank of Lieutenant-Colonel in the army and Commander in the navy, and to army Colonel and Navy Captain in 1925. The Washington Naval Treaty was signed on February 6,1922, Japan withdrew troops from the Siberian Intervention on August 28,1922. The Great Kantō earthquake devastated Tokyo on September 1,1923, on December 27,1923, Daisuke Namba attempted to assassinate Hirohito in the Toranomon Incident but his attempt failed. During interrogation, he claimed to be a communist and was executed, the General Election Law was passed on May 5,1925, giving all men above age 25 the right to vote. Prince Hirohito married his distant cousin Princess Nagako Kuni, the eldest daughter of Prince Kuniyoshi Kuni and they had two sons and five daughters. On December 25,1926, Hirohito assumed the throne upon his father, Yoshihitos, the Crown Prince was said to have received the succession. The Taishō eras end and the Shōwa eras beginning were proclaimed, the deceased Emperor was posthumously renamed Emperor Taishō within days. Following Japanese custom, the new Emperor was never referred to by his name, but rather was referred to simply as His Majesty the Emperor

Akihito
–
Akihito is the reigning Emperor of Japan. He is the 125th emperor of his line according to Japans traditional order of succession, Akihito succeeded his father Shōwa and acceded to the Chrysanthemum Throne on 7 January 1989. There has been ongoing coverage of his possible abdication due to age,31 December 2018 and 1 January 2019 has been mentioned as possible dates of such abdication. In Japan, the Emperor is never referred to by his given name, in writing, the Emperor is also referred to formally as The Reigning Emperor. The Era of Akihitos reign bears the name Heisei, and according to custom he will be renamed Emperor Heisei by order of the Cabinet after his death, at the same time, the name of the next era under his successor will also be established. Akihito was born in the Tokyo Imperial Palace, Tokyo City, Japan, and is the elder son and the fifth child of the Emperor Shōwa and Empress Kōjun. Titled Prince Tsugu as a child, he was raised and educated by his private tutors, unlike his predecessors in the Imperial family, he did not receive a commission as an army officer, at the request of his father, Hirohito. During the American firebombing raids on Tokyo in March 1945, Akihito and his younger brother, during the American occupation of Japan following World War II, Prince Akihito was tutored in the English language and Western manners by Elizabeth Gray Vining. He briefly studied at the Department of Political Science at Gakushuin University in Tokyo, Akihito was heir-apparent to the Chrysanthemum Throne from the moment of his birth. His formal Investiture as Crown Prince was held at the Tokyo Imperial Palace on 10 November 1952, in June 1953 Akihito represented Japan at the Coronation of Queen Elizabeth II in London. Crown Prince Akihito and Crown Princess Michiko made official visits to thirty-seven countries, upon the death of Emperor Hirohito on 7 January 1989, his eldest son the Crown Prince Akihito succeeded to the throne, with an enthronement ceremony taking place on 12 November 1990. In 1998, during a visit to the United Kingdom. Emperor Akihito underwent surgery for cancer on 14 January 2003. Since succeeding to the throne, Emperor Akihito has made an effort to bring the Imperial family closer to the Japanese people, the Emperor and Empress of Japan have made official visits to eighteen countries and to all forty-seven Prefectures of Japan. The Emperor and Empress also made a visit on Wednesday,30 March 2011 to a temporary shelter housing refugees of the disaster and this kind of event is also extremely rare, though in line with the Emperors attempts to bring the Imperial family closer to the people. Later in 2011 he was admitted to suffering from pneumonia. In February 2012 it was announced that the Emperor would be having a coronary examination, however, senior officials within the Imperial Household Agency have denied that there is any official plan for the monarch to abdicate. A potential abdication by the Emperor would require an amendment to the Imperial Household Act, on 8 August 2016, the Emperor gave a rare televised address, where he emphasized his advanced age and declining health, this address is interpreted as an implication of his intention to abdicate
