Hinode Onsen, now closed, was located in Nagoya, Aichi Prefecture. Its thermal sodium-chloride water reached 40°C, with an indoor bath, outdoor rotenburo and sauna.
Insider tip — Listed as closed — verify locally before visiting. Hinode (日の出 — sunrise) Onsen was in southern Nagoya's Tempaku/Mizuho border area. The name 'Hinode' evokes Japan's identity as the 'Land of the Rising Sun' (日本 Nihon/Nippon = origin of the sun); neighborhood sentos named Hinode were once common symbols of community renewal and optimism in postwar Japanese cities rebuilding after 1945.
