Yusenkyo Onsenkan, also known as Yushoka, is set in Saga city, the prefectural capital on Kyushu island. Its sodium-chloride water surfaces at 42°C with a pH of 7.3, alongside an indoor bath, a rotenburo and a sauna.
Insider tip — Saga Prefecture, the ceramics heart of Japan, produced the Arita and Imari porcelain traditions that shaped European fine china. The Yushoka onsen hall is a relaxing stop between visits to the ancient kiln sites, and the nearby Ureshino hot spring district is one of the finest in Kyushu.
