Saienji Onsen, in Komatsu (Ishikawa prefecture), heats sodium-chloride water to 41°C. The complex brings together an indoor bath, an outdoor rotenburo bath, and a sauna for a classic onsen break.
Insider tip — Saienji Onsen serves Komatsu City in the Kaga lowlands of Ishikawa Prefecture, whose cultural heritage is anchored in the Otabi Festival where spectacular elaborately decorated clay floats (hikiyama) carrying mechanical karakuri puppets parade through the city streets in one of Hokuriku most extravagant autumn celebrations. Komatsu is also the birthplace of Nishida Kitaro (1870-1945), Japan most influential 20th-century philosopher, whose philosophy of pure experience and place is commemorated in the city museum dedicated to his life and thought.
