Mie Tsu Onsen is a thermal bathing facility in Tsu, the prefectural capital of Mie Prefecture, Japan, a city known for having Japan's shortest place name and situated on the shore of Ise Bay — gateway to the sacred Ise Grand Shrine, Japan's holiest Shinto sanctuary visited by millions annually. The naturally chloride-sodium spring waters tapped here are valued in Japanese wellness tradition for their deeply warming and circulatory-stimulating properties, offering urban residents of Mie's capital city easy access to genuine therapeutic hot spring bathing. With the spiritual atmosphere of nearby Ise permeating the region, soaking in Tsu's chloride onsen waters provides a harmonious blend of physical relaxation and the quiet spiritual resonance of Japan's most sacred Shinto heartland.

Insider tip — Mie Tsu Onsen sits in the prefectural capital facing Ise Bay, where hot sodium-chloride water is drawn from deep beneath the coastal plain. The salty brine at 43 °C promotes circulation and is especially favored by local fishermen after long hours at sea. A short walk from the city center makes it an accessible urban thermal retreat.
