Iwamuro Onsen Ryokan ★★★★☆

Yumotoya

ゆもとや

Does Yumotoya allow tattoos? In a private bath

Private bath only

Two detached rooms with their own open-air hot-spring bath, renovated 2025, plus a reservable outdoor private bath.

Yumotoya doesn't publish a shared-bath policy, but two private-bath routes are on its own site: a reservable outdoor private bath drawing from the inn's hot-spring source, and two detached rooms renovated in July 2025 with their own attached open-air hot-spring bath.

Where it is

Tokyo STN Joetsu Shinkansen, then the JR Echigo Line about 2 h 50 Hotel location
Iwamuro STN
Tokyo is the door. Iwamuro is the Joetsu Shinkansen to Niigata, about two hours with no change, then a local Echigo Line train down the coast to Iwamuro station and a bus or taxi the last four kilometers into the onsen, about 2 h 50 in all..
