Originally built in the samurai style to provide housing for the high-ranking inspectors of the Tokugawa Shogunate, the residence was later enlarged with a section built in the merchant style architecture.
The entrance was maintained in the samurai style, and it is known as the "pine covered gate", due to the very old and beautifully shaped pine visible in this photo.
