History of Sakazuki Hot Spring | Development of Herring Fishing and Hot Springs
The history of Sakazuki Hot Spring is closely connected to the history of herring fishing in this area.
Prosperity of Herring Fishing
The Shakotan Peninsula, including Tomari Village, prospered greatly from herring fishing from the Edo period through the early Showa period. Particularly from the Meiji through Taisho periods, prosperous herring fishing resulted in the construction of luxurious facilities called “Herring Palaces.”
Sakazuki Fishing Port was also an important base for herring fishing, and in spring, massive quantities of herring would rush in, causing a phenomenon called “Gumi” (herring run) where the sea would become white with cloudiness.
Discovery and Development of Hot Springs
There are various theories about when Sakazuki Hot Spring was discovered, but it is believed to have been known to local people long ago. Full-scale development as a hot spring resort came later after herring fishing declined and the hot spring was recognized as a tourism resource.
With its designation as a national health resort hot spring area, its spring quality and environment received public recognition, and it has now become an important accommodation base for tourists visiting the Shakotan Peninsula.
Modern Sakazuki Hot Spring
Today’s Sakazuki Hot Spring retains vestiges of past herring fishing prosperity while serving as a quiet hot spring destination that heals its visitors. While Tomari Village is home to Hokkaido’s only nuclear power plant and plays a role in the regional economy, hot springs and tourism are also positioned as important industries.
Best Seasons to Visit Sakazuki Hot Spring
Sakazuki Hot Spring can be visited throughout the year, but each season offers different attractions.
Spring (April – June)
