SodiumChloruresBrome
Hira Onsen is located in Nagoya, Aichi Prefecture. Its thermal sodium-chloride water reaches 40°C, with an indoor bath, outdoor rotenburo and sauna on site.
Insider tip — Hira Onsen in northern Nagoya's residential outskirts is a classic neighborhood sento where Nagoya's famous 'asa-buro' (morning bath) tradition is practiced — arriving before 8am to soak before the workday is a Nagoya cultural institution essentially unknown elsewhere in Japan. The city's practical, hardworking character ('Nagoya-jin' are stereotyped as diligent and thrifty) extends to making the most of neighborhood thermal infrastructure.
