What Is the Kobayakawa Family Residence Main House?
The Kobayakawa Family Residence Main House (小早川家住宅主屋, Kobayakawa-ke Jūtaku Shuoku) is a single-storey timber house built in 1890 on a samurai estate in Jonai 2-chome, Shimabara City, Nagasaki Prefecture, and registered as a Registered Tangible Cultural Property on 23 February 2012. It has a building area of 194 square meters under a hip-and-gable roof laid with pantiles.
The house stands close to the middle of the plot and faces east. Of the four registered parts of the Kobayakawa Family Residence, it is the only building; the gate and the stone and brick walls are the frame, and this is the picture inside it.
Three Wings Set Like Flying Geese
The Kobayakawa Family Residence Main House is not a single block. It is three wings with different jobs. The reception wing faces the garden, and to its northwest come an entrance wing, which contains the family's Buddhist altar room, and a kitchen wing. The wings do not line up side by side. Each is shifted a little from the last, so the plan steps diagonally, an arrangement Japanese builders call gankō-gata after the staggered line of geese in flight.
Stepping the wings gives each one more outside walls. The reception wing opens toward the garden, the entrance wing greets visitors straight ahead of the gate, and the kitchen wing sits back out of sight. Guests, family life and the working kitchen each get a wing of their own rather than sharing one roof.
The principal room of the reception wing is a 10-mat room, and the Agency for Cultural Affairs notes its well-made Zashiki-kazari, the fixed decorative features of a formal Japanese room such as the alcove and shelves. The published records do not say exactly which features are there, so it is worth checking for yourself if you get inside on an open day.
Why It Was Registered, and When It Was Built
The Kobayakawa Family Residence Main House was registered for its contribution to the historic landscape. Nagasaki Prefecture values it as a house that preserves how a samurai residence in the Shimabara castle town was laid out. A Meiji-era house sitting within an Edo-period gate and stone wall shows the old samurai plot remaining in use as a home after the domain system ended.
The sources disagree slightly on the date. The Agency for Cultural Affairs database gives the era as Meiji 23, which corresponds to 1890, but its Western-calendar field reads 1898. Nagasaki Prefecture's database and a Nagasaki Shimbun report quoting the city board of education both give Meiji 23, or 1890. This article follows 1890, where the Japanese date and both other sources agree.
Seeing the Kobayakawa Family Residence Main House
Because the Kobayakawa Family Residence Main House sits in the middle of the plot, very little of it can be seen from outside the walls. You can go inside only when Shimabara City holds one of its limited public openings; during the December 2024 opening, visitors could see the house together with its pond garden.
On an open day, the entrance wing is directly ahead as you pass through the gate. The reception wing sits offset to the southeast, so if you look to your left from in front of the entrance you can see how the wings step away diagonally. The notices we checked said nothing about photography indoors, so ask the staff on the day.
