Jigokunuma Pond
Located not far from Sukayu Onsen, this pond was created about 800 years ago by an explosive volcanic eruption in the Hakkōda Mountains. Covering roughly 4,500㎡, it formed when hot spring water bubbling up in the area collected in an old explosion crater. Even today, steam vents-remnants of past volcanic activity-dot the surroundings, and the distinct scent of sulfur hangs in the air. This eerie atmosphere is what inspired the name “Jigokunuma,” or “Hell Pond.”
The sulfur smell is a bit strong, but the wild, natural vibe is awesome. Makes for some really striking photos!
