Saki no Yu Onsen - A Tattoo-Friendly Hot Spring in Shirahama, Wakayama

Perched dramatically on the rocky Pacific coastline, Saki no Yu Onsen (崎の湯) in Shirahama, Wakayama, offers one of Japan's most authentic and historically significant bathing experiences. Dating back over 1,400 years, this venerable hot spring is mentioned in Japan's oldest historical texts—the Nihon Shoki (Chronicles of Japan) and the Manyoshu poetry anthology—earning it a place among Japan's 'Three Great Ancient Hot Springs.'

​

Unlike many traditional bathhouses, Saki no Yu embraces visitors with tattoos, offering a rare opportunity to experience ancient Japanese bathing culture in its most primal form. Here, you'll soak in natural rock baths carved into coastal formations while waves crash just meters away, creating a multisensory experience that connects you directly to both Japan's bathing traditions and the raw power of nature.

Fully Tattoo-Friendly: Saki no Yu welcomes all tattooed visitors without restrictions on size, design, or coverage requirements, making it an ideal destination for international travelers with body art seeking an authentic onsen experience.

• Ancient Heritage: One of Japan's three oldest hot springs with documented use spanning 1,400+ years
• Oceanfront Experience: Bathe in natural rock pools where the Pacific Ocean spray occasionally mists your skin
• Tattoo-Friendly Environment: Complete acceptance of tattoos without restrictions
• Rustic Authenticity: Minimalist facilities preserve the primordial bathing experience unchanged for centuries
• Therapeutic Waters: Sodium chloride springs renowned for skin health, muscle relief, and circulation benefits
• Instagram-Worthy Views: Breathtaking ocean panoramas create unforgettable photo opportunities (from outside the bath area)
• Cultural Significance: Emperors and nobility have enjoyed these same waters since ancient times

At Saki no Yu, you'll immerse yourself in naturally heated sodium chloride springs, carefully temperature-controlled to a comfortable 42°C (107.6°F). The men's section offers the most dramatic ocean exposure, while the women's area provides slightly more privacy while maintaining sea views. As you soak, all your senses engage with the environment—the slightly salty water softens your skin, the distinct sulfur aroma fills your lungs, and the rhythmic crashing of waves creates nature's soundtrack.

​

The therapeutic waters, rich in sodium chloride and trace minerals, are reputed to ease neuralgia, joint pain, and various skin conditions. Many visitors report improved circulation and a profound sense of relaxation that continues long after leaving. Note that the rustic design means you won't find modern amenities like showers on-site—this is bathing as it was experienced centuries ago, focused entirely on the healing properties of the mineral waters and natural surroundings.

• Adult Admission (Ages 3+): ¥500
