Following the opening of Hakodate Port, the shogunate had the Matsumae clan build a jinya (encampment) to strengthen the defense of Ezochi.

During the Hakodate War in the first year of the Meiji era (1868), it was burned down and abandoned by its own garrison troops as the former shogunate army advanced. It is now managed as a nationally designated cultural property.

It has been developed as a historical park where visitors can stroll through the main enclosure, which retains its original appearance. Additionally, the approximately 800-meter-long tunnel of cherry blossom trees leading from the prefectural road to the jinya site is known as a famous spot for cherry blossoms. In autumn, the autumn leaves within the enclosure are a delight to the eyes.
