Introducing Fuji Five Lakes
The Fuji Five Lakes (Fuji go-ko) region is a postcardlike area around Fuji's northern foothills; its lakes act as natural reflecting pools for the mountain's perfect cone. Yamanaka-ko is the easternmost lake, followed by Kawaguchi-ko, Sai-ko, Shōji-ko and Motosu-ko. Particularly during the autumn kōyō (foliage) season, the lakes make a good overnight trip out of Tokyo, for leisurely strolling, lake activities and for hiking in the nearby mountains.
Fuji-Yoshida and Kawaguchi-ko are the most accessible and developed areas. Kawaguchi-ko is the most popular place to stay, with the best range of accommodation, but both make good bases if you plan on climbing Mt Fuji and don't intend on overnighting in a mountain hut.
