Mt Ou (1623m) & Mt Oni (1738m), Fuji-kawaguchiko City, Yamanashi Prefecture


If you want to have spectacular views of Mt Fuji, I recommend hiking the peaks surrounding Japan’s most famous volcano in December or January, when the weather is clear, and the most mountains are still snow-free. Considering the time and effort it takes to get to the area, it would be a shame to miss out on the spectacular views, which are some of the best in Japan.


Ridgewalking involves some ups and downs

The start of the trail is next to Iyashi no Sato いやしの里 near Lake Saiko, about forty minutes away by bus from Kawaguchiko station (it can take longer due to traffic). It takes one hour along an unused road to reach the entrance of the hiking trail, and from there it’s another hour of steep climbing to the top of Mt Ou 王ヶ岳 (“King mountain”). The reward for this effort is a wide view of Mt Fuji with Aokigahara Forest spread out at its feet.


The Tenshi Mountains to the South

Following the trail to the right, the next part is an enjoyable hike along a narrow ridgeline, past Mt Kagikake (1589) 鍵掛山, and all the way to Mt Oni 鬼ヶ岳 (“Demon mountain”) about two hours away. It’s best to factor in more time for this part since there are many spectacular views on the way: Mt Fuji, the Misaka mountains, the Tenshi Mountains, the Minami Alps, Yatsugatake, the Kofu valley, Oku-Chichibu mountains, and Kawaguchiko city with its lake.

From the summit, the path back down is to the right (South) towards Mt Settou (1710m) 雪頭ヶ岳 (not to be confused with nearby Mt Settou 節刀ヶ岳). After this last peak and final views, the trail heads steeply down the mountain through the forest, and ends back at Iyashi no Sato 90 minutes later, where one can catch a bus back to Kawaguchiko station.
