In Kashiba, Nara Prefecture, Kashiba Tonzuruho Onsen offers sodium-chloride thermal water at 40°C (104°F). An indoor bath, an outdoor rotenburo bath and a sauna make up this traditional Japanese onsen, valued for its enveloping warmth.
Insider tip — Kashiba is in western Nara Prefecture on the border with Osaka — the ancient Takenouchi Kaido (Japan's oldest national road, 615 AD) passes through here. 'Tonzuruho' is an unusual name that may reference a local geographical or historical feature of Kashiba; the city sits between the Yamato highlands and the Osaka plains, in the corridor traveled by Silk Road goods from Naniwa (Osaka port) to the ancient capitals of Asuka and Nara. Kashiba's archaeological sites include the Kakinomoto Jinja shrine associated with the great 7th-century poet Kakinomoto no Hitomaro.
