Takeshi Onsen Utsukushi no Yu, in Ueda (Nagano), offers bicarbonate water with a pH of 8, heated to 40°C. An indoor bath, an outdoor rotenburo bath and a sauna round out the offering.
Insider tip — Utsukushi no Yu, the beautiful spring, sits in Ueda, the city of the legendary Sanada clan who famously defeated Tokugawa forces twice at Ueda Castle in 1600. The NHK Taiga Drama Sanada Maru immortalised these warrior stories, and the castle ruins and Sanada museum are an inspiring prelude to a soak.
