Where we start

Six places where travellers ask most, opening one after another this winter.

Not just onsen

Living or training in Japan with tattoos means more than hot springs. We map these too.

  • Inside a sento: a tiled bath under a painted Mt Fuji mural.

    銭湯Sento

    Neighbourhood bathhouses, often the easiest yes in town.

  • Inside a cedar sauna with tiered benches and a stone stove.

    サウナSaunas

    Standalone saunas and sauna floors in bathhouses.

  • A wooden gym in morning light with a barbell rack and kettlebells.

    ジムGyms

    Day passes and memberships where ink is fine on the floor.

  • An outdoor pool with lane ropes at golden hour under summer clouds.

    プールPools

    Municipal, hotel and summer outdoor pools.

How a place gets listed

  1. Step 1

    We ask the venue

    By phone, email or LINE, in Japanese. Official policy pages count only when they are clear.

  2. Step 2

    We write down what they said

    Which baths, whether covers are allowed, the largest size, and the date we asked.

  3. Step 3

    We check again

    Every listing shows its last-checked date, and we re-check when travellers report a change.

Be first in the water.

We open with Tokyo in November 2026. Join the list and we'll send the launch guide.
