Namazu Onsen
Namazu Onsen is a hot spring town in Toyama, Japan. The water leaves the ground at 5–29.1°C, cool enough that the baths here are usually reheated. It measures pH 1–7.18 — strongly acidic, the kind that stings on a cut. Officially the water is classed as chloride spring and iron spring. Its sources put out around 109 litres a minute. 2 inns take visitors here.
Getting there
- Train to Toyama Station (Shinkansen)

The water here
Chloride spring
Salty water. The salt leaves a thin film on the skin, so you stay warm well after leaving the bath.
Iron spring
Turns reddish brown as the iron meets air. The water is clear at the source.

With tattoos
Many public baths still turn away visible tattoos, and the rule is set by each bath, not by the town. The reliable way round it is to bathe privately: a room with its own open-air bath, or an inn with a private bath you can book for yourselves.
