You can see a lot of stars from Rishiri Island when it's fine.

Amid the majestic forest is the Mt. Rishiri trailhead. You can walk to the spring in about 10 minutes, and there you will find "Kanro" natural mineral water springing up from the earth. The water here has been selected as one of the best natural mineral waters in Japan. This is the only water on the trail up the mountain.

Mt. Rishiri Hiking (Oshidomari Trail)

This trail is the most popular route up the mountain. There are no toilets on the way to the summit. Please purchase a portable latrine (¥400) in advance, and use it in the toilet booths that can be found by the side of the trail. Please be aware that weather conditions often change suddenly on Mt. Rishiri .
At the Eighth-stage there are many wild flowers just past the shelter hut. On a clear day, the whole of the Rishiri-, Rebun area, as well as the Taisetsu Mountain Range can be seen. *We can take you to the Mt. Rishiri trailhead at 4:45 a.m. for free.

【Distance to the peak: 8.4 km. (It takes about 6 hours up and 4 hours down.)
    

Skiing on Rishiri Island is on the bucket list for many Japan backcountry skiing aficionados. Powder skiing in Hokkaido is world renowned because of the abundance of amazingly light, fluffy powder snow that results from the weather systems that blow down from Siberia. Compared to most Hokkaido ski areas, Rishiri Island is much further north and closer to Siberia, so the powder can be even more amazing!

The best time to go backcountry skiing in Rishiri is probably late February. In late winter and early spring there's a slightly higher chance of clear days, although the main weather inhibitor to reaching the summit of Mt Rishiri is the wind, and the wind is not such a big factor at that time of year.
