Takamaru Onsen is located in Akashi, Hyogo Prefecture, facing the strait that connects Honshu to Awaji Island. Sodium-chloride thermal water flows at 40°C through an indoor bath, a rotenburo, and a sauna.
Insider tip — Takamaru Onsen lies near Akashi (明石) — home of the world's longest suspension bridge (Akashi Kaikyo Ohashi, 3,911 m span) and the 135°E meridian, Japan's official time standard (Japan Standard Time is named Akashi Standard Time). Akashi's local specialty is akashi-yaki — a softer, more delicate version of takoyaki (octopus balls) dipped in warm dashi broth rather than sauce.
