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

Steam drifts across the pavement before you reach the door. Hamawaki sits in the oldest onsen district in Beppu — the one named for springs that once bubbled up along the beach — and the building itself feels like an extension of that history: municipal, unfussy, built for daily use by people who live with hot water the way other cities live with tap.

Inside, two tubs. One hot — properly hot, around 45°C, the kind that makes you exhale on entry. One lukewarm, for longer soaks and recovery between rounds. The water is clear and soft, with a silky feel that regulars describe as gentle enough for every day. No outdoor baths, no resort trappings. This is a neighborhood sento-scale onsen that happens to run on natural spring water and stays open past midnight.

If you want the real Beppu — the one where locals outnumber tourists and tattooed guests step in without a second glance — Hamawaki is the entry point most visitors never find. It costs less than a vending machine coffee and delivers more than most hotel spas in the prefecture.

• Beppu's Oldest Spring District: Hamawaki is where Beppu's onsen culture began over a thousand years ago — the name itself means "springs from the beach," and the neighborhood still runs on that same geothermal energy.
• Tattoos Accepted, No Covers Needed: Oita Prefecture Tourism confirms tattoos are permitted throughout the facility, and guests report bathing openly in the communal bath without issue.
• Hot-and-Cool Dual Tubs: Two side-by-side pools at different temperatures let you alternate between a sharp 45°C soak and a cooler recovery bath — a rhythm most single-tub onsen can't offer.
• Deep-Night Soaking: Open until 1:00 AM, Hamawaki is one of the few onsen in Beppu where you can soak after dinner, after the bars, after everything else closes.

The hotter tub hits first — 45°C water that tightens your skin on contact and sends heat straight through your shoulders. Clear, colorless, and silky enough that you notice it when you towel off. The cooler tub beside it runs gentler, and the rhythm between the two is what keeps regulars coming back: hot, cool, hot, cool, until the tension leaves.

The bathing area is indoor only — tiled, bright, no-frills municipal design renovated in recent years with the dual-temperature setup. No rotenburo, no sauna, no extras. What you get is the water itself, drawn from a spring that's been feeding this neighborhood since before Beppu had a train station. Late-night sessions, when the crowds thin and the only sound is water flowing into stone, are worth timing your visit around.
