Shirotaro-yama lies in the Tokuami region of Oguni Town. Like the real Yudono-san, there are no trails to climb in summer. Instead, the only way to climb is on the heavy snow of winter. If the weather cooperates, from the summit you can see out to Tohoku’s Matterhorn Iwaigame-yama in the east, the Asahi Renpo to the north, and the Ide Renpo way day in the south.

The Oguni-Machi Sangakukai (Oguni Town Mountaineering Club) and NPOs host hiking events to Shirotaro-yama. For your safety, it is highly recommended you join one of these events. It goes without saying, but you can enjoy skiing or snowboarding on Shirotaro-yama when you’ve finished your hike!

Shirotaro-yama Trail (winter only, 3 hours one-way, bring experienced winter hiker)

Since there are no trails in the summer, the only time you can go is when snow has settled on the mountain in winter. Since it’s hard to know where to go, you MUST go with someone experienced with snow hiking. You will need Kanjiki, snowshoes, and stocks? Plus, since it takes a lot of energy to create a trail, you should change the lead hiker periodically. On the way back, by all means use a sleigh or other methods to reduce the time necessary on the mountain.

The road to the trailhead is paved. There is space for about 4 vehicles 60 m from the trailhead, but no parking in front of the houses.
