Akazawa Onsen Day Spa - A Tattoo-Friendly Hot Spring in Itō, Shizuoka

Perched dramatically on the rugged Izu Peninsula coastline, Akazawa Onsen Day Spa (赤沢日帰り温泉館) offers one of Japan's most breathtaking bathing experiences where traditional onsen culture meets modern wellness therapy. As you soak in the infinity-edge outdoor bath, the boundary between water and sky dissolves, creating the magical illusion that you're floating directly into the vast Pacific Ocean.

​

Unlike many traditional Japanese bathing facilities, Akazawa combines both therapeutic mineral waters and innovative thalassotherapy treatments using deep-sea water, making it a unique wellness destination for visitors seeking both relaxation and rejuvenation in Shizuoka Prefecture.

• Spectacular Ocean Views: Floor-to-ceiling windows and an infinity-edge outdoor bath offering uninterrupted Pacific Ocean panoramas
• Private Bath Variety: Four uniquely themed private open-air baths available for reservation, perfect for tattooed travelers
• Therapeutic Waters: Sodium chloride-rich waters renowned for skin beautification and muscle relaxation
• Wellness Fusion: Traditional onsen bathing combined with modern thalassotherapy and Thai massage treatments
• Day Trip Convenience: Full resort-quality amenities without overnight stay requirements
• Family-Friendly Environment: Accommodating pricing for children and spacious facilities suitable for family groups

The magic of Akazawa begins with its sodium chloride-rich waters, maintained at a comfortable 35.5°C—slightly cooler than many traditional onsen, allowing for extended, leisurely soaking without overheating. This weakly alkaline water gently opens pores and soothes tired muscles, particularly beneficial after hiking the scenic Izu trails or exploring nearby tourist sites.

​

What truly sets Akazawa apart is its architectural design that harmonizes with the natural surroundings. The outdoor rotenburo creates a seamless visual connection with the ocean horizon, while inside, therapeutic options ranging from bubbling jet baths to the DHC-branded sauna offer a comprehensive wellness circuit. For tattooed visitors, the private themed baths—each with distinct personality and decor—provide both cultural immersion and reassuring privacy.
