Tōnosawa Ichinoyu Honkan - A Tattoo-Friendly Hot Spring in Hakone Onsen, Kanagawa

Tōnosawa Ichinoyu Honkan, established in 1630, stands as a living monument to Japan's rich bathing culture and traditional hospitality. This four-story wooden inn, crafted in the elegant sukiya-zukuri architectural style, has earned recognition as a National Tangible Cultural Property while remaining in the same family's care for an astounding 16 generations. Perched alongside the flowing Hayakawa River, this historic ryokan blends centuries-old charm with thoughtful modern touches, including its renowned Italian marble baths that offer a unique twist on the traditional onsen experience.

​

For tattooed travelers exploring Hakone's legendary hot springs, Tōnosawa Ichinoyu Honkan represents an opportunity to step back in time while enjoying the therapeutic benefits of Japan's volcanic waters in a setting once frequented by Edo-period travelers along the historic Tokaido Road.

Slip into the alkaline waters (pH ~9.5) of Tōnosawa Ichinoyu Honkan and feel centuries of stress melt away. These naturally heated springs are prized for their skin-softening properties and ability to relieve muscle fatigue—a welcome relief after exploring Hakone's mountainous landscape. For tattooed guests, the private Italian marble baths and in-room rotenburo offer an ideal sanctuary where you can soak without concerns about policies or covering up.

​

The bathing experience is elevated by the gentle background melody of the Hayakawa River flowing just beyond the baths, creating a multisensory connection to nature that embodies the essence of traditional Japanese bathing culture. As steam rises around you, it's easy to imagine the countless travelers who have sought rejuvenation in these same waters since the Edo period.
