The Stone Age was a broad prehistoric period during which stone was used to make implements with an edge, a point, or a percussion surface. The period lasted 3.4 million years and ended between 8700 BCE and 2000 BCE with the advent of metalworking. Stone Age artifacts include tools used by modern humans and by their predecessor species in the genus Homo, by the earlier contemporaneous genera Australopithecus and Paranthropus. Bone tools were used during this period as well but are preserved in the archaeological record; the Stone Age is further subdivided by the types of stone tools in use. The Stone Age is the first period in the three-age system of archaeology, which divides human technological prehistory into three periods: The Stone Age The Bronze Age The Iron Age The Stone Age is contemporaneous with the evolution of the genus Homo, the only exception being the early Stone Age, when species prior to Homo may have manufactured tools. According to the age and location of the current evidence, the cradle of the genus is the East African Rift System toward the north in Ethiopia, where it is bordered by grasslands.
The closest relative among the other living primates, the genus Pan, represents a branch that continued on in the deep forest, where the primates evolved. The rift served as a conduit for movement into southern Africa and north down the Nile into North Africa and through the continuation of the rift in the Levant to the vast grasslands of Asia. Starting from about 4 million years ago a single biome established itself from South Africa through the rift, North Africa, across Asia to modern China, called "transcontinental'savannahstan'" recently. Starting in the grasslands of the rift, Homo erectus, the predecessor of modern humans, found an ecological niche as a tool-maker and developed a dependence on it, becoming a "tool equipped savanna dweller"; the oldest indirect evidence found of stone tool use is fossilised animal bones with tool marks. Archaeological discoveries in Kenya in 2015, identifying the oldest known evidence of hominin use of tools to date, have indicated that Kenyanthropus platyops may have been the earliest tool-users known.
The oldest stone tools were excavated from the site of Lomekwi 3 in West Turkana, northwestern Kenya, date to 3.3 million years old. Prior to the discovery of these "Lomekwian" tools, the oldest known stone tools had been found at several sites at Gona, Ethiopia, on the sediments of the paleo-Awash River, which serve to date them. All the tools come from the Busidama Formation, which lies above a disconformity, or missing layer, which would have been from 2.9 to 2.7 mya. The oldest sites containing tools are dated to 2.6–2.55 mya. One of the most striking circumstances about these sites is that they are from the Late Pliocene, where previous to their discovery tools were thought to have evolved only in the Pleistocene. Excavators at the locality point out that: "...the earliest stone tool makers were skilled flintknappers.... The possible reasons behind this seeming abrupt transition from the absence of stone tools to the presence thereof include... gaps in the geological record."The species who made the Pliocene tools remains unknown.
Fragments of Australopithecus garhi, Australopithecus aethiopicus and Homo Homo habilis, have been found in sites near the age of the Gona tools. In July 2018, scientists reported the discovery in China of the oldest stone tools outside Africa, estimated at 2.12 million years old. Innovation of the technique of smelting ore began the Bronze Age; the first most significant metal manufactured was bronze, an alloy of copper and tin, each of, smelted separately. The transition from the Stone Age to the Bronze Age was a period during which modern people could smelt copper, but did not yet manufacture bronze, a time known as the Copper Age, or more technically the Chalcolithic, "copper-stone" age; the Chalcolithic by convention is the initial period of the Bronze Age. The Bronze Age was followed by the Iron Age; the transition out of the Stone Age occurred between 6000 BCE and 2500 BCE for much of humanity living in North Africa and Eurasia. The first evidence of human metallurgy dates to between the 5th and 6th millennium BCE in the archaeological sites of Majdanpek and Pločnik in modern-day Serbia, though not conventionally considered part of the Chalcolithic or "Copper Age", this provides the earliest known example of copper metallurgy.
Note the Rudna Glava mine in Serbia. Ötzi the Iceman, a mummy from about 3300 BCE carried with him a flint knife. In regions such as Sub-Saharan Africa, the Stone Age was followed directly by the Iron Age; the Middle East and southeastern Asian regions progressed past Stone Age technology around 6000 BCE. Europe, the rest of Asia became post-Stone Age societies by about 4000 BCE; the proto-Inca cultures of South America continued at a Stone Age level until around 2000 BCE, when gold and silver made their entrance. The Americas notably did not develop a widespread behavior of smelting Bronze or Iron after the Stone Age period, although the technology existed. Stone tool manufacture continued after the Stone Age ended in a given area. In Europe and North America, millstones were in use until well into the 20th century, still are in many parts of the world; the terms "Stone Age", "Bronze Age", "Iron Age" were never meant to suggest that advancement and time periods in prehistory are only measured by the type of tool material, rather than, for
Hokkaido known as Ezo, Yeso, or Yesso, is the second largest island of Japan, the largest and northernmost prefecture. The Tsugaru Strait separates Hokkaido from Honshu; the two islands are connected by the undersea railway Seikan Tunnel. The largest city on Hokkaido is its capital, its only ordinance-designated city. About 43 km north of Hokkaido lies Russia. To its east and north-east are the disputed Kuril Islands; the Nihon Shoki, finished in 720 AD, is said to be the first mention of Hokkaido in recorded history. According to the text, Abe no Hirafu led a large navy and army to northern areas from 658 to 660 and came into contact with the Mishihase and Emishi. One of the places Hirafu went to was called Watarishima, believed to be present-day Hokkaido. However, many theories exist in relation to the details of this event, including the location of Watarishima and the common belief that the Emishi in Watarishima were the ancestors of the present-day Ainu people. During the Nara and Heian periods, people in Hokkaido conducted trade with Dewa Province, an outpost of the Japanese central government.
From the Middle Ages, the people in Hokkaido began to be called Ezo. Hokkaido subsequently became known as Ezogashima; the Ezo relied upon hunting and fishing and obtained rice and iron through trade with the Japanese. During the Muromachi period, the Japanese created a settlement at the south of the Oshima Peninsula; as more people moved to the settlement to avoid battles, disputes arose between the Japanese and the Ainu. The disputes developed into a war. Takeda Nobuhiro killed the Ainu leader and defeated the opposition in 1457. Nobuhiro's descendants became the rulers of the Matsumae-han, granted exclusive trading rights with the Ainu in the Azuchi-Momoyama and Edo periods; the Matsumae family's economy relied upon trade with the Ainu. They held authority over the south of Ezochi until the end of the Edo period in 1868; the Matsumae clan rule over the Ainu must be understood in the context of the expansion of the Japanese feudal state. Medieval military leaders in northern Honshū maintained only tenuous political and cultural ties to the imperial court and its proxies, the Kamakura Shogunate and Ashikaga Shogunate.
Feudal strongmen sometimes located themselves within medieval institutional order, taking shogunal titles, while in other times they assumed titles that seemed to give them a non-Japanese identity. In fact, many of the feudal strongmen were descended from Emishi military leaders, assimilated into Japanese society; the Matsumae clan were of Yamato descent like other ethnic Japanese people, whereas the Emishi of northern Honshu were a distinctive group related to the Ainu. The Emishi were conquered and integrated into the Japanese state dating back as far as the 8th century, as result began to lose their distinctive culture and ethnicity as they became minorities. By the time the Matsumae clan ruled over the Ainu most of the Emishi were ethnically mixed and physically closer to Japanese than they were to Ainu; this dovetails nicely with the "transformation" theory that native Jōmon peoples changed with the infusion of Yayoi immigrants into the Tōhoku rather than the "replacement" theory which posits that one population was replaced by another.
There were numerous revolts by the Ainu against the feudal rule. The last large-scale resistance was Shakushain's Revolt in 1669–1672. In 1789, a smaller movement, the Menashi–Kunashir rebellion, was crushed. After that rebellion, the terms "Japanese" and "Ainu" referred to distinguished groups, the Matsumae were unequivocally Japanese. In 1799–1821 and 1855–1858, the Edo Shogunate took direct control over Hokkaido in response to a perceived threat from Russia. Leading up to the Meiji Restoration, the Tokugawa Shogunate realized there was a need to prepare northern defenses against a possible Russian invasion and took over control of most of Ezochi; the Shogunate made the plight of the Ainu easier, but did not change the overall form of rule. Hokkaido was known as Ezochi until the Meiji Restoration. Shortly after the Boshin War in 1868, a group of Tokugawa loyalists led by Enomoto Takeaki temporarily occupied the island, but the rebellion was crushed in May 1869. Ezochi was subsequently put under control of Hakodate Prefectural Government.
When establishing the Development Commission, the Meiji Government introduced a new name. After 1869, the northern Japanese island was known as Hokkaido; the primary purpose of the development commission was to secure Hokkaido before the Russians extended their control of the Far East beyond Vladivostok. Kuroda Kiyotaka was put in charge of the venture, his first step was to journey to the United States and recruit Horace Capron, President Grant's Commissioner of Agriculture. From 1871 to 1873 Capron bent his efforts to expounding Western agriculture and mining with mixed results. Capron, frustrated with obstacles to his efforts returned home in 1875. In 1876, William S. Clark arrived to found an agricultural college in Sapporo. Although he only remained a year, Clark left a lasting impression on Hokkaido, inspiring the Japanese with his teachings on agriculture as well as Christianity
Kagoshima Prefecture is a prefecture of Japan located on the island of Kyushu. The capital is the city of Kagoshima. Kagoshima Prefecture corresponds to the ancient Japanese provinces Ōsumi and Satsuma, including the northern part of the Ryukyu Islands; this region played a key role in the Meiji Restoration, the city of Kagoshima was an important naval base during Japan's 20th century wars and the home of admiral Tōgō Heihachirō. More recent incidents are the sinking of a North Korean spy ship in 2001 by the Coast Guard, salvaged and exhibited in Tokyo, the abduction of an office clerk from a Kagoshima beach in 1978 by agents from the same country; this became known only under the Koizumi administration. Kagoshima Prefecture is located at the southwest tip of Kyushu on the Satsuma Peninsula and Ōsumi Peninsula; this prefecture includes a chain of islands stretching further to the southwest of Kyushu for a few hundred kilometers. The most important group is the Amami Islands. Surrounded by the East China Sea to the west, Okinawa Prefecture in the south, Kumamoto Prefecture to the north, Miyazaki Prefecture to the east, it has 2,632 km of coastline.
It has a bay called Kagoshima Bay, sandwiched by two peninsulas, Satsuma and Ōsumi. Its position made it a'gateway' to Japan at various times in history. While Kyushu has about 13 million people, there are less than 2 million in this prefecture; the prefecture boasts a chain of active and dormant volcanoes, including the great Sakurajima, which towers out of the Kagoshima bay opposite Kagoshima city. A steady trickle of smoke and ash emerges from the caldera, punctuated by louder mini-eruptions on an daily basis. On active days in Kagoshima city an umbrella is advisable to ward off the ash. Sakurajima is one of Japan's most active volcanoes. Major eruptions occurred in 1914, when the island mountain spilled enough material to become permanently connected to the mainland, a lesser eruption in 1960. Volcanic materials in the soil make Sakurajima a source for record daikon radishes the size of a basketball. Many beaches around the Kagoshima Bay are littered with well-worn pumice stones. A crater lake in the southwestern tip of the prefecture, near the spa town of Ibusuki, is home to a rare species of giant eel.
As of March 31, 2008, 9% of the total land area of the prefecture was designated as Natural Parks, namely the Kirishima-Yaku and Unzen-Amakusa National Parks. Most of the economic sector is focused in Kagoshima City and the surrounding area, corresponding to the extent of the former Satsuma Province; the eastern part of the prefecture, the former Ōsumi Province, is rural and shows a general population decline. The prefecture has strong agricultural roots, which are reflected in its most well-known exports: green tea, sweet potato, Pongee rice, Satsuma ware and Berkshire pork. Kagoshima prefecture's production of bonito flakes is second only to that of Shizuoka. In addition it produces Japan's largest volume of unagi eels; the Japan Aerospace Exploration Agency has several facilities within the prefecture, including the country's main launch facility on Tanegashima and the Uchinoura Space Center. The prefecture's gross domestic product is 4.834 trillion yen. The following is a list of Kagoshima Prefecture's cities, its administrative districts with their constituent towns and villages: Nineteen cities are located in Kagoshima Prefecture: Kagoshima These are the towns and villages in each district: Kagoshima Rebnise, a professional basketball team, was founded in 2003 and competes in the second division of the national B.

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
The Soviet Union the Union of Soviet Socialist Republics, was a socialist state in Eurasia that existed from 1922 to 1991. Nominally a union of multiple national Soviet republics, its government and economy were centralized; the country was a one-party state, governed by the Communist Party with Moscow as its capital in its largest republic, the Russian Soviet Federative Socialist Republic. Other major urban centres were Leningrad, Minsk, Alma-Ata, Novosibirsk, it spanned over 10,000 kilometres east to west across 11 time zones, over 7,200 kilometres north to south. It had five climate zones: tundra, steppes and mountains; the Soviet Union had its roots in the 1917 October Revolution, when the Bolsheviks, led by Vladimir Lenin, overthrew the Russian Provisional Government which had replaced Tsar Nicholas II during World War I. In 1922, the Soviet Union was formed by a treaty which legalized the unification of the Russian, Transcaucasian and Byelorussian republics that had occurred from 1918. Following Lenin's death in 1924 and a brief power struggle, Joseph Stalin came to power in the mid-1920s.
Stalin committed the state's ideology to Marxism–Leninism and constructed a command economy which led to a period of rapid industrialization and collectivization. During his rule, political paranoia fermented and the Great Purge removed Stalin's opponents within and outside of the party via arbitrary arrests and persecutions of many people, resulting in at least 600,000 deaths. In 1933, a major famine struck the country. Before the start of World War II in 1939, the Soviets signed the Molotov–Ribbentrop Pact, agreeing to non-aggression with Nazi Germany, after which the USSR invaded Poland on 17 September 1939. In June 1941, Germany broke the pact and invaded the Soviet Union, opening the largest and bloodiest theatre of war in history. Soviet war casualties accounted for the highest proportion of the conflict in the effort of acquiring the upper hand over Axis forces at intense battles such as Stalingrad and Kursk; the territories overtaken by the Red Army became satellite states of the Soviet Union.
The post-war division of Europe into capitalist and communist halves would lead to increased tensions with the United States-led Western Bloc, known as the Cold War. Stalin died in 1953 and was succeeded by Nikita Khrushchev, who in 1956 denounced Stalin and began the de-Stalinization; the Cuban Missile Crisis occurred during Khrushchev's rule, among the many factors that led to his downfall in 1964. In the early 1970s, there was a brief détente of relations with the United States, but tensions resumed with the Soviet–Afghan War in 1979. In 1985, the last Soviet premier, Mikhail Gorbachev, sought to reform and liberalize the economy through his policies of glasnost and perestroika, which caused political instability. In 1989, Soviet satellite states in Eastern Europe overthrew their respective communist governments; as part of an attempt to prevent the country's dissolution due to rising nationalist and separatist movements, a referendum was held in March 1991, boycotted by some republics, that resulted in a majority of participating citizens voting in favor of preserving the union as a renewed federation.
Gorbachev's power was diminished after Russian President Boris Yeltsin's high-profile role in facing down a coup d'état attempted by Communist Party hardliners. In late 1991, Gorbachev resigned and the Supreme Soviet of the Soviet Union met and formally dissolved the Soviet Union; the remaining 12 constituent republics emerged as independent post-Soviet states, with the Russian Federation—formerly the Russian SFSR—assuming the Soviet Union's rights and obligations and being recognized as the successor state. The Soviet Union was a powerhouse of many significant technological achievements and innovations of the 20th century, including the world's first human-made satellite, the first humans in space and the first probe to land on another planet, Venus; the country had the largest standing military in the world. The Soviet Union was recognized as one of the five nuclear weapons states and possessed the largest stockpile of weapons of mass destruction, it was a founding permanent member of the United Nations Security Council as well as a member of the Organization for Security and Co-operation in Europe, the World Federation of Trade Unions and the leading member of the Council for Mutual Economic Assistance and the Warsaw Pact.
The word "Soviet" is derived from a Russian word сове́т meaning council, advice, harmony and all deriving from the proto-Slavic verbal stem of vět-iti, related to Slavic věst, English "wise", the root in "ad-vis-or", or the Dutch weten. The word sovietnik means "councillor". A number of organizations in Russian history were called "council". For example, in the Russian Empire the State Council, which functioned from 1810 to 1917, was referred to as a Council of Ministers after the revolt of 1905. During the Georgian Affair, Vladimir Lenin envisioned an expression of Great Russian ethnic chauvinism by Joseph Stalin and his supporters, calling for these nation-states to join Russia as semi-independent parts of a greater union, which he named as the Union of Soviet Republics of Europe and Asia. Stalin resisted the proposal, but accepted it, although with Lenin's agreement changed the name of the newly proposed sta
The Edo period or Tokugawa period is the period between 1603 and 1868 in the history of Japan, when Japanese society was under the rule of the Tokugawa shogunate and the country's 300 regional daimyō. The period was characterized by economic growth, strict social order, isolationist foreign policies, a stable population, "no more wars", popular enjoyment of arts and culture; the shogunate was established in Edo on March 24, 1603, by Tokugawa Ieyasu. The period came to an end with the Meiji Restoration on May 1868, after the fall of Edo. A revolution took place from the time of the Kamakura shogunate, which existed with the Tennō's court, to the Tokugawa, when the samurai became the unchallenged rulers in what historian Edwin O. Reischauer called a "centralized feudal" form of shogunate. Instrumental in the rise of the new-existing bakufu was Tokugawa Ieyasu, the main beneficiary of the achievements of Oda Nobunaga and Toyotomi Hideyoshi. Powerful, Ieyasu profited by his transfer to the rich Kantō area.
He maintained two million koku of land, a new headquarters at Edo, a strategically situated castle town, had an additional two million koku of land and thirty-eight vassals under his control. After Hideyoshi's death, Ieyasu moved to seize control from the Toyotomi clan. Ieyasu's victory over the western daimyō at the Battle of Sekigahara gave him control of all Japan, he abolished numerous enemy daimyō houses, reduced others, such as that of the Toyotomi, redistributed the spoils of war to his family and allies. Ieyasu still failed to achieve complete control of the western daimyō, but his assumption of the title of shōgun helped consolidate the alliance system. After further strengthening his power base, Ieyasu installed his son Hidetada as shōgun and himself as retired shōgun in 1605; the Toyotomi were still a significant threat, Ieyasu devoted the next decade to their eradication. In 1615, the Tokugawa army destroyed the Toyotomi stronghold at Osaka; the Tokugawa period brought 250 years of stability to Japan.
The political system evolved into what historians call bakuhan, a combination of the terms bakufu and han to describe the government and society of the period. In the bakuhan, the shōgun had national authority and the daimyō had regional authority; this represented a new unity in the feudal structure, which featured an large bureaucracy to administer the mixture of centralized and decentralized authorities. The Tokugawa became more powerful during their first century of rule: land redistribution gave them nearly seven million koku, control of the most important cities, a land assessment system reaping great revenues; the feudal hierarchy was completed by the various classes of daimyō. Closest to the Tokugawa house were the shinpan, or "related houses", they were twenty-three daimyō on the borders of Tokugawa lands. The shinpan held honorary titles and advisory posts in the bakufu; the second class of the hierarchy were the fudai, or "house daimyō", rewarded with lands close to the Tokugawa holdings for their faithful service.
By the 18th century, 145 fudai controlled the greatest assessed at 250,000 koku. Members of the fudai class staffed most of the major bakufu offices. Ninety-seven han formed the tozama, former opponents or new allies; the tozama were located on the peripheries of the archipelago and collectively controlled nearly ten million koku of productive land. Because the tozama were least trusted of the daimyō, they were the most cautiously managed and generously treated, although they were excluded from central government positions; the Tokugawa shogunate not only consolidated their control over a reunified Japan, they had unprecedented power over the emperor, the court, all daimyō and the religious orders. The emperor was held up as the ultimate source of political sanction for the shōgun, who ostensibly was the vassal of the imperial family; the Tokugawa helped the imperial family recapture its old glory by rebuilding its palaces and granting it new lands. To ensure a close tie between the imperial clan and the Tokugawa family, Ieyasu's granddaughter was made an imperial consort in 1619.
A code of laws was established to regulate the daimyō houses. The code encompassed private conduct, dress, types of weapons and numbers of troops allowed. Although the daimyō were not taxed per se, they were levied for contributions for military and logistical support and for such public works projects as castles, roads and palaces; the various regulations and levies not only strengthened the Tokugawa but depleted the wealth of the daimyō, thus weakening their threat to the central administration. The han, once military-centered domains, became mere local administrative units; the daimyō did have full administrative control over their territory and their complex systems of retainers and commoners. Loyalty was exacted from religious foundations greatly weakened by Nobunaga and Hideyoshi, through a variety of control mechanisms. Like Hideyoshi, Ieyasu encouraged foreign trade but was suspicious of outsiders, he wanted to make Edo a major port, but once he learned that the Europeans favored ports in Kyūshū and that China had rejected his plans for official trade, he moved to control existing trade
The Tōhoku region, Northeast region, or Northeast Japan consists of the northeastern portion of Honshu, the largest island of Japan. This traditional region consists of six prefectures: Akita, Fukushima, Iwate and Yamagata. Tōhoku retains a reputation as a scenic region with a harsh climate. In the 20th century, tourism became a major industry in the Tōhoku region. In mythological times, the area was known as Azuma and corresponded to the area of Honshu occupied by the native Ainu; the area was the Dewa and the Michinoku regions, a term first recorded in Hitachi-no-kuni Fudoki. There is some variation in modern usage of the term "Michinoku". Tōhoku's initial historical settlement occurred between the seventh and ninth centuries, well after Japanese civilization and culture had become established in central and southwestern Japan; the last stronghold of the indigenous Emishi on Honshu and the site of many battles, the region has maintained a degree of autonomy from Kyoto at various times throughout history.
The haiku poet Matsuo Bashō wrote Oku no Hosomichi during his travels through Tōhoku. The region is traditionally known as a less developed area of Japan; the catastrophic 9.0-Magnitude earthquake and tsunami on March 11, 2011, inflicted massive damage along the east coast of this region, killed 15,894 people and was the costliest natural disaster which left 500,000 people homeless along with radioactive fallout from the Fukushima Daiichi nuclear disaster. Masamune, feudal lord of Date clan, expanded trade in the Tōhoku region. Although faced with attacks by hostile clans, he managed to overcome them after a few defeats and ruled one of the largest fiefdoms of the Tokugawa shogunate, he worked on many projects to beautify the region. He is known to have encouraged foreigners to come to his land. Though he funded and promoted an envoy to establish relations with the Pope in Rome, he was motivated at least in part by a desire for foreign technology, similar to that of other lords, such as Oda Nobunaga.
Further, once Tokugawa Ieyasu outlawed Christianity, Masamune reversed his position, though disliking it, let Ieyasu persecute Christians in his domain. For 270 years, Tōhoku remained a place of tourism and prosperity. Matsushima, for instance, a series of tiny islands, was praised for its beauty and serenity by the wandering haiku poet Matsuo Bashō, he showed sympathy for Christian traders in Japan. In addition to allowing them to come and preach in his province, he released the prisoner and missionary Padre Sotelo from the hands of Tokugawa Ieyasu. Date Masamune allowed Sotelo as well as other missionaries to practice their religion and win converts in Tōhoku; the most used subdivision of the region is dividing it to "North Tōhoku" consisting of Aomori and Iwate Prefectures and "South Tōhoku" consisting of Yamagata and Fukushima Prefectures. The population collapse of Tōhoku, which began before the year 2000, has accelerated, now including dynamic Miyagi. Despite this, Sendai City has grown due to the disaster.
The population collapse of Aomori and Akita Prefectures, Honshu's 3 northernmost, began in the early 1980s after an initial loss of population in the late 1950s. Fukushima Prefecture, prior to 1980, had traditionally been the most populated, but today Miyagi is the most populated and urban by far. Tōhoku, like most of Japan, is mountainous, with the Ōu Mountains running north-south; the inland location of many of the region's lowlands has led to a concentration of much of the population there. Coupled with coastlines that do not favor seaport development, this settlement pattern resulted in a much greater than usual dependence on land and rail transportation. Low points in the central mountain range make communications between lowlands on either side of the range moderately easy. Tōhoku was traditionally considered the granary of Japan because it supplied Sendai and the Tokyo-Yokohama market with rice and other farming commodities. Tōhoku provided 20 percent of the nation's rice crop; the climate, however, is harsher than in other parts of Honshū due to the stronger effect of the Siberian High, permits only one crop a year on paddy fields.
In the 1960s, steel, chemical and petroleum refining industries began developing.
