The geyser is officially designated as a natural monument by the local municipality.
The water temperature at the spout is approximately 100 degrees Celsius at the point of origin.
The geyser erupts with consistent pressure due to the specific underground geological structure of the Mine Onsen area.
It is one of the few places in Japan where you can observe a natural, high-pressure geyser eruption regularly.
The park provides mesh baskets specifically designed to lower eggs directly into the hot spring water for boiling.
Mine Onsen Water Spout Park is famous for its natural hot spring geyser, which erupts at regular intervals, reaching heights of up to 30 meters. The geyser, known as 'Hofuku-to,' was first discovered in 1926 and remains the primary attraction of the park. Geothermal energy from the spout is utilized to boil eggs, which visitors can purchase and prepare on-site. The park is located within the Kawazu area, a region historically significant for its early-blooming cherry blossoms. Visitors can observe the eruption from a designated viewing area located directly adjacent to the spout. The park grounds feature a footbath area fed by the same geothermal water source. It serves as a testament to the volcanic activity characteristic of the Izu Peninsula.
The viewing platform directly facing the geyser during the peak of its eruption.
Bring a small towel for the footbath so you can dry your feet afterward.
Wear shoes that are easy to take on and off if you plan to use the footbath facilities.
Check the eruption status board near the entrance to time your visit around the peak spout height.
Assuming the geyser erupts continuously; it operates on an intermittent schedule that requires waiting.
Closed on specific weekdays throughout the year for maintenance; check local schedules before visiting.
Do not touch the water near the main spout as it is boiling hot; use only designated footbath areas.
