Area:Mt. Fuji/Fuji Five Lakes

The Fujiko (Fujisan’s worshippers) started to design a faith involving numerous pilgrimages to religious place including a pilgrimage to the “Uchihakkai” (the eight lakes around the base of the mountain including the Fuji Fives Lakes, Oshino Hakkai and a couple of lakes a little further from Fujisan). Although the places for these religious pilgrimages changed over time, the Fuji Fives Lakes, which include Lake Saiko, Lake Shojiko and Lake Motosuko, continued to remain object of religious ablutions throughout the ages. Of the Fuji Five Lakes, Lake Motosuko boasts a particularly outstanding scenic landscape, and has therefore been the source of inspiration for many works of art. “Lake Side in Spring” is one of those. It was photographed by Koyo Okada, who has been continuouslyphotographing Fujisan throughout his life. His photograph was used in the design for the 5,000 yen and 1,000 yen bills.
On the southern shore of Lake Saiko lies Aokigahara, otherwise known as the “Sea of Trees,” where one can stay either at one of the shoreline campsites or at one of the minshuku inns. The lakeshore is an expansive, peaceful environment that is often used by camping/open-air schools, music groups, etc. as a retreat. The Japanese kunimasu trout, which has been threatened with extinction, has made a return to these parts for the first time in 70 years and this has really become a major talking point. The kunimasu trout originally hails from Lake Tazawa in Akita Prefecture, but it is believed that some kunimasu were released into Lake Saiko and propagated. Furthermore, Lake Saiko is also the native habitat for a variant of the yamanakaensis, designated as a natural treasure by Yamanashi Prefecture.
