Mt. Iou硫黄山


Mt. Iou is a volcano with an elevation of 512 meters located close to the town of Teshikaga in Hokkaido. “Atosanupuri” is another name for Mt. Iou. You can enjoy dynamic scenery with white smoke and noise rising from the surface. Despite the ferocity of the volcano, many alpine plants still grow on the lowlands, including marsh tea which flowers from the middle to the end of June. The autumn leaf season is also recommended. Currently, the mountain is closed due to the danger of falling rocks, but you can enjoy the walk from Kawayu Onsen to Mt. Iou instead.

Hokkaido Main Areas


Not just a prefecture but an island of its own, Hokkaido is the most northerly prefecture and island of the Japanese archipelago. Arriving in Hokkaido, which is rural and bursting with breathtaking nature, means entering a world where vast national parks, towering mountains, and natural hot springs can be found at every turn. Come December, these natural splendors freeze over and morph into a winter wonderland.
