Sengen Park

Located at the northern edge of the hot spring town, Sengen Park is a place where visitors can observe a geyser up close. A geyser is a natural phenomenon in which steam and hot water erupt from the ground. Although the timing varies depending on natural conditions, watching hot water at approximately 80 degrees Celsius well up from the ground is a truly impressive sight.
Jigokudani is also home to a geyser known as Tessen-ike. Rather than shooting high into the air, the hot water wells up vigorously, bubbling as if it were boiling. Other well-known geysers in Hokkaido can be found at Shikabe Onsen and Rausu Onsen.
Another distinctive feature of this park is the nine large, brightly colored metal pillars arranged around the grounds. According to local lore, they were left behind by the guardian deity of the hot springs. Each pillar represents a different blessing—such as good health, prosperity, or family harmony—and corresponds to a particular direction and color.
The ninth pillar, a golden one, is said to lie hidden deep beneath the park. Inspired by the legends of Jigokudani, the image of the demon was adopted as part of a local revitalization initiative. Combined with the traditional principles of the Nine Star Ki system, these pillars have earned a reputation as a modern-day spiritual power spot.
