Nagano Prefecture located in/on physical feature Honshu
History
Geography
Nagano is an inland prefecture and it borders more prefectures than any other in Japan, bordering Gunma Prefecture, Saitama Prefecture, Yamanashi Prefecture, and Shizuoka Prefecture to the east, Niigata Prefecture to the north, Toyama Prefecture and Gifu Prefecture to the west, and Aichi Prefecture to the south. Nagano contains the point furthest from the sea in the whole of Japan—this point lies within the city of Saku. The province's mountains have made it relatively isolated, and many visitors come to Nagano for its mountain resorts and hot springs. Nine of the twelve highest mountains in Japan can be found in Nagano and one of its lakes, Lake Kizaki, is a beach resort popular for its water attractions and games. The climate is predominantly alpine with warm summers, cold snowy winters and less intense humidity than the lower lying coastal areas. 
As of 1 April 2014, 21% of the total land area of the prefecture was designated as Natural Parks; namely the Chichibu Tama Kai, Chūbu-Sangaku, Jōshin'etsu Kōgen, and Minami Alps National Parks; Myōgi-Arafune-Saku Kōgen, Tenryū-Okumikawa, and Yatsugatake-Chūshin Kōgen Quasi-National Parks; and Chūō Alps, Enrei Ōjō, Hijiriyama Kōgen, Mibugawa Suikei, Ontake, and Tenryū Koshibu Suikei Prefectural Natural Parks.
