I came on the regular sightseeing Basilica. It was October and the sky was clear. The smoke from the mountain is amazing. There were many Taiwanese tourists, and two groups asked us to take a commemorative photo. I wish I could take good photos. The smell of sulfur was the most amazing thing I have ever smelled. There was a smell in the bus.

I could tell immediately because there was smoke rising from the mountain. It looks like a rugged, pretty vast sulphur hill. The unique sulfur smell is so tight that it smells pretty bad.

Free parking available on the day if you have paid the parking fee at Lake Mashu Daiichi Observatory

I happened to pass by and saw something steaming out, yellow mountain face
What the hell was that all about? I stopped by without any plans.
Because I was paying for parking at Mashuko First Observatory
This is where you can get free parking if you visit on the day.
It is still an active volcano, from the early Meiji period to the Showa 30s (late 1800 to mid 1900)
It is said that sulfur was mined until
The smell of sulphur in the surrounding area suddenly reminded me of Owakudani in Hakone.
It was a pity that I couldn't go up to the mountain face just to shoot because I didn't have time.
Looking back, a big rainbow hangs over the rest house,
I've seen rainbows three times today alone.

Even more than in Noboribetsu, here you feel like you are in contact with the “breath” of the earth.
aug. 2024 • Venner
Having visited, in addition to Mt. Io, also the fumaroles of Noboribetsu, a comparison between these two places of Hokkaido island comes naturally to me.
In Noboribetsu I saw an entire district organized around the fumaroles. Everything seems exploited to the maximum from a tourist point of view.
Here the view of the sulfur vents (at least those visited by large crowds; I abstract here from the possible guided walks, reserved for a few hikers, along the entire mountain) is more concentrated in space. But it's also more intense. Mount Io appears in its essential nakedness, animated only by vapors and yellowish rocks. Nowhere like here was it easy for me to imagine Dante walking in the “Inferno” created by his poetic imagination.
And I regretted having been able to stay so little, due to the restrictions of our visit program.

Mount Io (硫黄山) or Iozan (translated as “sulphur mountain”) is one of my family’s visited attractions in our 10-day Hokkaido self-drive vacation. Although there are a few volcanoes named “Iozan” in Japan, there is only one Iozan that is otherwise known as “Atosa Nupuri” in Ainu language, meaning “naked mountain” due to its flora-barren rocky surface. It is at this “volcanic activity alert 1 level (i.e. safe to visit)” active volcano at about 508 metres tall/high in Hokkaido’s Akan Volcanic Complex where we spent about 1 hour on a cloudy weekday afternoon.
Getting there: Mount Io (Iozan) is located between Lake Kussharo and Lake Mashū and is only 5 minutes’ drive from the hot spring resort town of Kawayu Onsen. We arrived here from Motoyama Observatory/Lookout Park in our rental car via Google Map and Apple Map on the Apple Car Play, and parked our car at one of the 120 car park lots. We paid ¥500 for the parking in which the parking ticket allowed us to park at Lake Mashu Observatory 1 car park for free (and vice versa). There is no entry fee at this attraction.
You could also take the train to Kushiro Station then take the JR Senmo Line to JR Kawayu Onsen Station (90-110 minutes); from this station walk about 30 minutes on the Aoba Tunnel Trail to the foot of Mount Io. Alternatively, you could also walk the 2.4 km Tsutsujigahara Nature Trial from Kawayu Onsen Eco-museum Centre to the foot of Mount Io in about 60 minutes. These trials exhibit the diverse ecosystem of plants that grow in normal soil and those that grow in acidic soil as you approach Mount Io; in spring, you could see white Labrador tea flowers.
The attraction: After parking our car, we walked toward the brown National Parks of Japan information board that provides information on the history of mining at Mount Io and four walking trials to Mount Io: Tsutsujigahara Nature Trial (about 60 minutes), Aoba Tunnel Trail (about 30 minutes), short Sakhalin Spruce Forest Trail (about 30 minutes) and long Sakhalin Spruce Forest Trail (about 60 minutes). The sulphur mine was closed in 1963 due to decreased demand for sulphur. Even though we are some 200 metres away from the foot of Mount Io, we could already smell the sulphur. Looking straight, I could see steam rising or billowing in the distant.
A 5-minute walk across rough terrain took me to the barricaded “fence” (made of vertical wood logs inter-connected with three ropes) at the foot of Mount Io and a really fascinating out-of-this-world sight of large yellow fumaroles of sulphur crystals whose sight are intermittently blocked by visible steam that is vented from the ground around the fumarole and through the fumaroles. The steam moved according to the direction of the gentle wind. While the predominant gas that is emitted is water vapour, trace amounts of sulphur gases, i.e. sulphur dioxide and hydrogen sulphide are also emitted which react to form solid sulphur and water vapour. At certain places on either side of the fence, I saw little hot springs of boiling water (I believe over 100 degrees Celsius) gushing out which I was mindful not to touch it! Furthermore, follow all safety instructions of not going beyond the fence otherwise you may be scalded by the vented steam. The wood log - ropes “fence” is about 270 metres long with about 100 metres being close to the steaming fumaroles and hot springs.
After the close encounter with hot steam and sulphur fumaroles, it was time to head back to the Mount Io Rest House named MOKMOK Base, which was just renovated; it opens 8am to 5pm late October to late April and 8:30am to 5:30pm late April to late October. It is here that you could shop for souvenir gifts, learn the history of mining and geography of Mount Io at the "Mt. Io Museum” (unfortunately the exhibits are in Japanese), sit down on sofa seats and enjoy views of Mount Io through a 5 metre wide glass at the MOKMOK Theatre, relax at MOKMOK Terrace with its iconic “harder” Mount Io rocks complementing natural “softer” furnishings such as trees and try the local specialties at the MOKMOK Café & Marche such as Iozan Ontama soft serve ice-cream, Ontama cup curry, deep fried sweet potato and the eggs (¥150 per egg and ¥600 for 5 eggs) that are cooked in hot spring water from Mount Io - there is an interesting technique of peeling the egg shells using tape and these eggs do not turn black.
I enjoyed the following at Mount Io:
(1) a very rare experience of being at the base or foot of an active volcano, and not in the environment of hot lava but in a geothermal environment of hot gas and steam
(2) easy accessibility to the base of the volcano via walking
(3) appreciating Mother Earth’s relentless energy from the continuous venting of steam and hearing the unique sound of venting steam
(4) marvelling at the few of the over 1500 sulphur fumaroles at a safe distance and proximity of about 8 metres
(5) very few visitors at the fenced viewing area at the base of the volcano and the visitors generally do not stay longer than 10 minutes
(6) relaxing in a cooler atmosphere inside the MOKMOK Café and Marche after the encounter at the hot geothermal environment
I recommend Mount Io as a “must visit” while you are in the Akan- Mashū National Park. In fact, why not visit Lake Mashū, Lake Kussharo and Lake Akan (and even Lake Onnetō) before or after Mount Io? For those of you who do not have asthma and similar medical conditions but do not like the smell of sulphur, you could just do a quick walk to the base, snap a few photos quickly and then walk back – how often we get a chance to experiencing our Earth in a special way at an active “sulphur volcano” which is at the “safe to visit” level coming out from the 24 hours volcanic activity monitoring and surveillance? There is a sign at the MOKMOK Café and Marche building that mentions that you could go to the basement of the building if somehow you have not enough time to escape from the eruption (which I hope that will not happen). As this attraction requires walking on uneven terrain, do wear a pair of sturdy walking shoes. For those who are adventurous, you could join the popular Atosanupuri Trekking Tour from late May to early November (¥13000 per person).

The fog was still strong, but as soon as the Pirika tourist bus entered the parking lot, there was a strong sulfur smell. We walked to the foot of the mountain, but the fog made visibility about 5 meters. Tourists can only go as far as the stop line, but it was very hot. And smelly. There was no promenade, so it might be best to follow the person in front of you. At the rest house, we had the specialty boiled eggs.

It reminded me of the hellish scene in Akira Kurosawa's "Dreams". The wind was blowing downwind from the parking lot, so the smell and the pain in my eyes scared me. The yellow color of the sulfur spewing out was so scary that it seemed to say, "Don't come near me."

The weather was good, so it felt like a completely otherworldly place and there were many things to see. It felt like hell. The smell was worse than I imagined, so I couldn't let my children go near it.

You can admire the views of Mt. Io, also known as Sulphur Mountain. It is quite active. You will see steam escaping from the earth. The ground is warm to the touch. It's an amazing place.

一瞬に大火傷をする様な・今でも噴出が続いている様は一見の価値が
あります。この雄大さには驚きでした!
