Fukagawa Onsen Tokiwa-yu 深川温泉 常盤湯
A real spring (sodium chloride), renovated in 2023: timed sauna sessions, often with a wait
In business for 80 years according to the operator, the sentō closed for a complete renovation and reopened on 16 March 2023 under the new name ‘Fukagawa Onsen Tokiwa-yu’. The spring is a real sodium chloride mineral water: a rare feature among Tokyo's public baths, which usually heat plain mains water.
