History and Characteristics of Ishida Onsen
A Historic Hot Spring Continuing Since Taisho 3
Since its founding in 1914 (Taisho 3), Ishida Onsen has been loved by many hot spring therapy visitors and tourists for over 100 years. Originally located along the coast near Cape Esan at the southeastern tip of the Oshima Peninsula, it relocated to its current location at 117-7 Kashiwano-cho, Hakodate City, Hokkaido following a flood in 2002. Even after the relocation, it continues to be cherished by local residents and distant visitors with unchanged spring quality and warm hospitality.
While preserving traditions that have continued under the foothills of Esan in a naturally blessed environment, it provides comfortable accommodation that adapts to modern times.
Spectacular Location Overlooking the Tsugaru Strait
One of Ishida Onsen’s greatest charms is its location. The setting that allows one to overlook the entire Tsugaru Strait provides visitors with an unforgettable view. The seascape visible through the windows changes character with the seasons and time of day, and the sea viewed while bathing in the hot spring is particularly special.
Especially at dusk, the sunset sinking into the sea is beautiful and creates a romantic atmosphere. Moreover, on clear days, one can see Honshu on the opposite shore, making it a precious place where you can appreciate the proximity of Hokkaido and Honshu.
