Spa Solani Yamato Onsen is set in Kure, Hiroshima Prefecture. Its sodium-chloride thermal water emerges at 41°C (106°F). The site includes an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — Kure is deeply connected to the Imperial Japanese Navy's tragic final act — the Yamato battleship (the world's largest and most heavily armored warship, 72,000 tons) was built in Kure's shipyards and sank in April 1945 en route to a suicide defense of Okinawa with only enough fuel for a one-way trip. Spa Solani's 'Yamato Onsen' honors this history directly; the Kure Maritime Museum (Yamato Museum) displays a 1:10 scale model. Kure also produces excellent Seto Inland Sea seafood including oysters and local tai (sea bream).
