What Is the Kobayakawa Family Residence Stone Wall?
The Kobayakawa Family Residence Stone Wall (小早川家住宅石塀, Kobayakawa-ke Jūtaku Ishibei) is the late-Edo stone boundary wall, built roughly between 1751 and 1830, that encloses a samurai estate in Jonai 2-chome, Shimabara City, Nagasaki Prefecture; it was registered as a Registered Tangible Cultural Property on 23 February 2012. It stands about 1.6 meters high and runs for 98.7 meters in total.
The wall wraps around the east, south and west sides of the plot and the northwest corner, and a further section stands between the front gate and the main house. Apart from the brick wall on the north side, the outline of the whole estate is drawn by this stone.
Three Colors of Shimabara Stone in a Tortoiseshell Pattern
The Kobayakawa Family Residence Stone Wall is built of Shimabara stone. According to the Agency for Cultural Affairs, the stones come in several colors, including grey, pink and blue, and are cut and fitted in the Kikkōzumi manner. In kikkozumi each stone face is dressed to a roughly hexagonal shape so the blocks interlock like the plates of a tortoise shell. Because the joints never run in one straight line, the method is regarded as resistant to collapse.
The top of the wall is finished differently. Above the courses of cut stone sits a capping of split stones about the size of a fist. Close up, the contrast between the neat hexagons below and the rough stones on top is obvious.
Stones of different colors are mixed together in the same face rather than sorted. Stand close and you will find a grey block sitting next to one with a pink cast and another with a bluish tone.
The Curve Between Gate and House
Nagasaki Prefecture draws attention to the section between the front gate and the main house, which is built on a curve. Where the outer walls mark the plot in straight lines, this inner stretch bends gently, steering the eye and the feet from the gate toward the front door.
This part lies inside the grounds, so it can only be seen when Shimabara City opens the house to the public. If you visit on an open day, compare it with the straight runs of the outer wall.
Why the Stone Wall Was Registered
The Kobayakawa Family Residence Stone Wall was registered for its contribution to the historic landscape. The Agency for Cultural Affairs and Nagasaki Prefecture both describe it as preserving the character of samurai residences in the Shimabara castle town. It is the oldest of the four registered parts of the Kobayakawa Family Residence, and together with the gate it keeps the Edo-period outline of the estate intact.
Seeing the Kobayakawa Family Residence Stone Wall
The outer sections of the Kobayakawa Family Residence Stone Wall face the street and can be seen at any time. Starting at the front gate on the east and walking south and then around the west side, you can follow most of its 98.7 meters on foot. At the northwest corner the stone ends and the brick wall on the north side takes over.
To see the colors and the tortoiseshell shapes, stop and look at the stones at eye level. The wall runs along working streets, so watch for traffic and do not step onto the property.
