Noboribetsu Onsen (day trip)

Noboribetsu Onsen is Hokkaido's most famous hot spring resort, nestled in a lush mountain valley where sulfurous waters bubble up naturally from the earth, creating an otherworldly landscape of steaming pools and colorful mineral deposits. Beyond the public bath houses and resort hotels, the surrounding forests offer scenic hiking trails and the dramatic Hell Valley (Jigokudani) where volcanic activity continues to shape the terrain. This is where locals and visitors alike escape to soak away stress while surrounded by pristine nature.
