Old Samurai Houses

When Shimabara Castle was built, a residence for samurai earning a stipend of 70 koku or less was built on the west side of the outer compound.
During times of battle, it was the residence of soldier (infantry) units whose main force used guns, so it was also known as a gun town.
The Yamamoto residence, Shinozuka residence, and Torita residence are open to the public for free, and you can see what samurai life was at the time.
