Noboribetsu Onsen has a typical hot spring town atmosphere, and you can see geysers spewing out at Sengen Park. However, it would be a waste to be satisfied with just the hot spring town area! If you go a little further into the area, you will find even deeper ways to enjoy the area. Noboribetsu Onsen is also famous for Jigokudani, which can be accessed right from the hot spring town. The steam gushing out of the fumaroles in the rock face, combined with the smell of sulfur, will get you in the mood for sightseeing. There is a promenade so it is easy to stroll around, and it makes for impressive photos. However, if you have come all the way to Noboribetsu Onsen, why not go a little further and head for Oyunuma? Oyunuma is the remains of an explosion crater that occurred when Mt. Hiyori erupted. It is about 1km in circumference and 22m deep, and sulfur springs at about 130℃ gush out from the bottom of the swamp. The sight of steam rising from the surface of the swamp is something you rarely see anywhere else. Nearby is another swamp called Oku-no-Yu, which, although smaller, resembles an even more intense hot water kiln and is enveloped in the strong smell of sulfur. If you want to see the whole picture of Oyunuma and take photos, we recommend going to Hiyoriyama Oyunuma Observatory. The mountain path is about 300m up, but it is well maintained so you can walk there in light clothing. You can see some spectacular views, especially during the autumn foliage season. Well, if you've come all the way to Oyunuma, here's a must-see spot. The hot springs that overflowed from Oyunuma became a river, the Oyunuma River. A flowing river with hot springs and steam coming out of it is quite a rare sight, isn't it? What's more, there is a place where you can use the Oyunuma River as a footbath. There is a promenade along the river, so just walk along it. About 500m from Oyunuma, you will come across the Oyunuma River Natural Footbath. It's a strange feeling to dip your feet in the river in the middle of nature and feel the warmth. The temperature varies depending on the season and weather, but on average it's around 40°C. Be sure to bring a towel and wear clothes that cover your knees to enjoy this special experience. By the way, if you are visiting by car, you will need to park at the Oyunuma Parking Lot, which requires a fee. The ticket you receive here can also be used at the Jigokudani Parking Lot at the entrance to Jigokudani, so be sure not to lose it. Also, please note that the Oyunuma Parking Lot is closed during the winter (usually from early December to late April) and the promenade to the Oyunuma River natural footbath may also be closed. *If you would like to know more about the atmosphere of Noboribetsu Oyunuma Natural Footbath, please check out our YouTube channel "Hot Springs Tour of Hokkaido"! <Interview cooperation> Noboribetsu International Tourism and Convention Association Address: 60 Noboribetsu Onsencho, Noboribetsu City, Hokkaido Phone: 0143-84-3311 Official website: https://noboribetsu-spa.jp/ Facebook: https://www.facebook.com/noboribetsuonsen
