The Kikuyas were a rich merchant family who helped build and run the old castle town of Hagi. Their residence was built in 1602 and is one of the oldest and best preserved example of Edo Period merchant architecture in Japan.
The interiors of the buildings are filled with displays, including an office area. In many ways the Kikuya residence was built way above their station as merchants were the lowest of the 4 classes with only various "non-persons" below them, but as the Edo period went on they became richer and richer and the highest class, the samurai, became poorer and poorer.
The kitchens and domestic areas are also open and filled with artifacts.
Previously I posted on the gardens surrounding the residence, but next up is the neighboring park-like garden that contains a more modern mansion residence
