Japanese hot‑spring spas in Oita and Kanagawa reopen after extensive renovations

The City Spa Tenku in the Oita Station building, operated by the Oita municipal hot‑spring facility, reopened on July 3 after a three‑month refurbishment. The upgrade added a glass‑enclosed sauna on the 21st floor with direct elevator access, privacy‑enhancing film on the indoor baths, and extended operating hours to midnight.

In Kanagawa’s Oku‑Yugawara region, the ryokan Yukui unveiled three newly renovated guest rooms in May 2026. Each floor‑dedicated suite combines a private sauna, a source‑directed natural hot‑spring bath, and panoramic forest views, and the launch includes a promotional coupon for early guests. Both projects aim to boost regional tourism by offering upscale onsen experiences within modernized facilities.
