Originally a Japanese Imperial mansion, it is now managed by the city and was opened as a park. The park was built over an area that was covered by a lava flow from Mt. Fuji in 1890.
At the center of the park is Kohamaga pond. The pond was once a water reservoir but is now almost depleted. As a result, lava rocks at the bottom of the pond can now be seen.
