Kaimonji Onsen - A Tattoo-Friendly Hot Spring in Beppu Onsen, Oita

Tucked just minutes from Beppu Station stands Kaimonji Onsen (海門寺温泉), a beloved municipal bath that has been soothing locals and visitors alike since 1936. This unpretentious gem represents the authentic soul of Beppu's bathing culture, offering a glimpse into everyday Japanese life rarely found in more tourist-oriented establishments. Following thoughtful renovations in 2010, this historic bathhouse now combines traditional charm with barrier-free accessibility, making it a welcoming haven for all visitors—including those with tattoos.

​

Unlike many traditional Japanese onsen, Kaimonji embraces diversity with its open tattoo policy, positioning it as an ideal first onsen experience for international travelers seeking authentic immersion without anxiety or restrictions. Here, you'll soak alongside locals in mineral-rich waters that have been revered for generations for their therapeutic properties.

Fully Tattoo-Friendly: Kaimonji Onsen welcomes guests with tattoos of all sizes and styles without requiring covers or imposing any restrictions, making it a stress-free bathing experience for tattooed travelers exploring Beppu's famous hot springs.

Slipping into Kaimonji's sodium-hydrogen carbonate waters (pH 7.4) feels like dissolving the day's tensions away. These mineral-rich baths—known locally as "beauty waters"—leave your skin noticeably softer while improving circulation and easing muscle stiffness. Many tattooed visitors appreciate how these alkaline waters enhance their ink's appearance, temporarily bringing vibrant colors to life.

​

What sets Kaimonji apart is its thoughtful temperature options. The main bath maintains approximately 40°C (104°F)—the perfect temperature for experienced bathers—while a separate lukewarm bath (around 38°C/100°F) offers a gentler introduction for onsen newcomers or those sensitive to heat. The baths are deep enough for shoulder immersion, allowing for complete relaxation while taking in the soothing sounds of this historic bathhouse.
