About
Iide Sanso is a mountain lodge in Oguni, Yamagata, in the Iide hot spring area. The baths are natural hot spring water, separate for men and women, and the bathrooms are stocked with shampoo, body soap and hair dryers. Day-use bathing (higaeri nyuyoku, 日帰り入浴) is open to visitors who are not staying. The lodge has 18 rooms and runs room-only for now, with meals suspended. Hikers and anglers once filled it, and today it is a quiet, simple place. It closes for the winter and for a period to clean the pipe that brings the spring water in, so check before going.
