The Minamiaso Field Hotel, a stationary resort offering accommodation in trailers with private onsen and dome tents, has opened in Minamiaso, Kumamoto Prefecture. The project is aimed at relaxing stays surrounded by nature and long-term living.
A day-use onsen, Ki no Kayu (also referred to as Ki no Ka Yu in some sources), reopened after renovation in March 2026. The operator states that the resort is designed for peaceful relaxation in a natural environment.
