This place was so amazing that the memory of the moment I stepped foot on this active volcano with the clouds of steam and the sulfur smell bursting their way through my sinuses, still haunts me, in a very very good way. We came here...More

If you are anywhere near this place, you have to visit it. It is absolutely amazing. Some of the hot springs are fenced off but there are many you can go right up and see, and feel what is going on. A very strong smell...More

Iouzan is interesting, well worth a visit. Bonus is the autum leaves around. Most people drive there or visit by tour bus. However, the approx. one hour (one way) natural trail starting from the Eco Museum to Iouzan is an easy walk offering diverse and...More

We'd walked from the Eco museum. Easy and pleasant walk with changes in the micro environment that were really interesting. The hot spring and steam vents were most interesting too.

Located at the midpoint between Lake Kussharo and Lake Mashu, this is a national park that will not be missed. Parking is 500yen for both Lake Mashu and Iouzan so make sure you allocate sufficient time to visit both places in a day.

We stopped on our trip and we were pleased with the scenery. It looks as if you step on some planet. The ground is grey and there is a lot of steam and yellow sulfur on the ground. The smell is terrible! But it makes...More
