Jigokudani Onsen Korakukan - A Tattoo-Friendly Hot Spring in Yudanaka Shibu, Nagano

Nestled deep in Nagano's misty mountains, Jigokudani Hot Spring Korakukan (地獄谷温泉後楽館) offers one of Japan's most extraordinary bathing experiences. This historic ryokan, established in 1864, predates even the famous Snow Monkey Park and holds the distinction of being where wild Japanese macaques first began their now-iconic hot spring bathing tradition. Unlike many traditional onsen, Korakukan provides tattooed travelers with a rare opportunity to experience authentic Japanese bathing culture while potentially sharing the waters with curious snow monkeys.

​

This 150-year-old mountain retreat, accessible only by a forest trail, represents the perfect marriage of cultural immersion and natural wonder—a place where tattooed visitors can soak in mineral-rich waters while surrounded by pristine alpine wilderness and, if luck is on your side, observe Japan's most photogenic wildlife enjoying the same therapeutic waters.

Tattoo-Friendly with Modesty Option: Korakukan welcomes tattooed guests in all baths, with the mixed-gender outdoor bath traditionally requiring a small modesty towel (available for rent) that can discreetly cover tattoos if desired, though this isn't strictly enforced for tattoos specifically.

• Wild Monkey Encounters: The only onsen in Japan where wild snow monkeys might join you for a soak, especially during winter months
• Historic Heritage: Over 150 years of continuous operation, offering a glimpse into traditional Japanese bathing culture
• Tattoo-Welcoming Atmosphere: Relaxed approach to tattoos compared to many traditional onsen
• Authentic Ryokan Experience: Family-run inn serving multi-course kaiseki meals featuring seasonal mountain ingredients
• Secluded Natural Setting: Located at the end of a 2km forest trail, far from crowds and modern distractions
• Private Family Baths: Bookable private onsen for intimate, tattoo-friendly soaking
• Cultural Significance: Historic birthplace of "Go" strategy game innovations by masters who retreated here

Soaking at Korakukan offers a sensory journey unlike any other onsen in Japan. The outdoor mixed-gender bath (rotenburo) provides panoramic views of snow-covered mountains in winter and lush forest in summer, while the volcanic waters maintain a soothing temperature of approximately 40°C (104°F) year-round. The gentle sulfur aroma mingles with crisp mountain air as steam rises from the surface, creating an otherworldly atmosphere that perfectly complements the "Hell Valley" name.

​

The mineral-rich waters—containing sulfur, calcium, and magnesium—are renowned for relieving muscle tension, improving circulation, and soothing skin conditions. What truly sets Korakukan apart, however, is the possibility of sharing your bath with Japanese macaques, particularly during winter mornings when the monkeys occasionally descend from the mountains to warm themselves. While not guaranteed, these peaceful primate encounters create unforgettable moments where nature and culture intersect in steaming volcanic waters.
