Yamanashi Prefecture capital Kōfu
Yamanashi Prefecture (山梨県, Yamanashi-ken) is a prefecture of Japan located in the Chūbu region of Honshu. Yamanashi Prefecture has a population of 817,192 (1 January 2019) and has a geographic area of 4,465 km2 (1,724 sq mi). Yamanashi Prefecture borders Saitama Prefecture to the northeast, Nagano Prefecture to the northwest, Shizuoka Prefecture to the southwest, Kanagawa Prefecture to the southeast, and Tokyo to the east.
Kōfu is the capital and largest city of Yamanashi Prefecture, with other major cities including Kai, Minamiarupusu, and Fuefuki. Yamanashi Prefecture is one of only eight landlocked prefectures, and the majority of the population lives in the central Kōfu Basin surrounded by the Akaishi Mountains, with 27% of its total land area being designated as Natural Parks. Yamanashi Prefecture is home to many of the highest mountains in Japan, and Mount Fuji, the tallest mountain in Japan and cultural icon of the country, is partially located in Yamanashi Prefecture on the border with Shizuoka Prefecture.15th to 19th centuries
Among the many Kaigenji generations, those of the Takeda, Ogasawara, and Nanbu families were particularly prosperous. During the Sengoku period of the 16th century, Takeda Shingen attained the status of daimyō and built Tsuzuji Mansion and the Yōgai Castle in Kōfu. From this base, he attempted to unify and control Japan.
After Takeda's death in 1582, Kai-no-Kuni came under the control of the Oda and Toyotomi clans before being subsumed into the Tokugawa shogunate during the Edo period. Beneath the Edo shogunate, the Kōfu clan (based in Kuninaka, or Central and Western Yamanashi) and the Yamura clan (based in Gunnai, or Eastern Yamanashi) were formed, but in 1724 the area came under the direct control of the Shogunate. With the development of the Kōshū Kaidō (highway) and Fuji River transport, goods, materials and culture flowed into the region.
By the mid-19th century, the contradictions of military government and clan system caused stability to erode and resistance to erupt across Japan, paving the way for the Meiji Restoration of 1868.1945 to present
The capital city, Kōfu, suffered extensive damage during a major air raid on the night of 6 July 1945. From 1945 onwards, as part of economic initiatives introduced under the post war Government of Occupation, agricultural land reforms significantly increased the number of individual farms and promoted fruit farming and viticulture throughout the prefecture. At first with limited success in 1946, but on a much more sustained basis in 1951, dairy farming, introduced by American Paul Rusch, became a feature of highland pastures surrounding the town of Kiyosato.Small scale manufacturing industries and commerce grew at rapid speed during the expansion of the post-war Japanese economy.  The 1982 opening of the Chūō Expressway also led to significant growth in service industries, transport logistics and tourism.
In common with many similar sized cities during the 1990s, rapid growth in car ownership, out of town shopping, and improved transportation links to Tokyo, caused a drop in commercial activity and land values in the center of the prefectural capital Kōfu. To counterbalance this trend the prefectural government launched a city center revitalization plan in 2008, promoting downtown tourist attractions such as redeveloped land North of Kōfu station, Maizuru Castle Park and new residential, cultural and government office facilities.
