A new experience for me, hot bubbling thermal water, yellow sulphuric deposits and a dramatic setting under this mountain.short walks around, really interesting.

Io-zan or, otherwise known as Mt. Io, literally translates to sulphur mountain. So as the name suggests, the mountain is known for its sulphur-emitting fumaroles. The presence of sulphur-emitting fumaroles also means that you’ll catch a whiff of this rotten-egg smell permeating through the air the moment you step out of your vehicle. In fact, most people in my tour group ran straight for the visitors’ centre to avoid the smell! I was lucky enough to get a tailwind, so that made the experience a lot better. From the carpark, you have to walk a short distance to get closer to the fumaroles, and the route can be quite rocky in some areas, so watch where you’re going! I think if you’re interested in geology, you tend to be able to appreciate these things a bit more. Unfortunately, sulphur-emitting fumaroles are all that Mount Io has to offer, and there isn’t really anything else to see, so if you are really a huge fan of geosciences, I recommend going somewhere else that has more landforms/features to offer than just fumaroles.

Awesome to be so close to geological activity. It was a special experience for our 2 children. However, The sulphur vents were the only thing there to see, we paid parking and stayed only a few minutes, although parking fee was not too high, 410 Jpy.
