Misono Shin Onsen is located in the Misono district of Amagasaki, Hyogo, near Osaka. Its sodium-chloride thermal water reaches 41°C (pH 7.3), with an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Amagasaki is the birthplace of Osamu Tezuka — the 'god of manga' who created Astro Boy (Tetsuwan Atom), Black Jack, and Buddha, defining Japanese comics and animation for generations. The city's industrial heritage (steel, textiles) and its manga legacy make it one of Japan's most culturally contradictory urban spaces. Misono Shin Onsen serves the working neighborhoods of a city that has quietly transformed from steel mills to cultural destination. The sento tradition here is genuinely working-class — neighbors gather in the baths as they have for generations.
