This place is written as [奥の湯] in Japanese.
Okunoyu is situated to the east of Ohyunuma Pond. It is a small pond known for its sulfur spring, which creates numerous crater-like holes on the surface due to the sulfur gushing out from the bottom. This unique sight is quite fascinating and distinctively characteristic of this area in Hokkaido, offering visitors a glimpse of what might be considered a hellish landscape.
