Kamikōchi (上高地 Upper Highlands) is a remote mountainous highland in the western portion of Nagano Prefecture, Japan, which has been preserved in its natural state. It has been designated as one of Japan's National Cultural Assets. It is sometimes referred to as the "Japanese Yosemite," although it is considerably smaller than its American counterpart. The highlands reach an altitude of 1,500 m (4,900 ft). The kanji 神垣内 (Kami-ko-uchi) were also used to write "Kamikōchi," but 上高地 (Kami-kō-chi) has become the common way to write the name.
