With the opening of Hakodate Port, the shogunate ordered the Matsumae clan to build a jin'ya to strengthen the defense of Ezo. During the Battle of Hakodate in 1868, as shogunate deserters advanced, the jin'ya was burned down and abandoned by the defending forces, and is now managed as a nationally designated cultural property.

It has been developed as a historic park, and you can stroll around the Honjin compound, which still retains its appearance from the time of the castle, as well as the 800m-long cherry blossom tunnel that runs from the prefectural road to the remains of the jinya, which is known as a famous cherry blossom viewing spot. In autumn, the autumn leaves within the compound are a feast for the eyes.
