Koike Family Warehouse

A wealthy family, the Yamamura's had their main house, a teahouse, and a storehouse around a central garden.

A structure built to house the ships that were being constructed to protect Hagi from nautical attacks. The sea once reached the boathouse, so ships could enter and exit the port.

The Yamanaka family were local seafood salesmen. They sold from here as well as sending fish to buyers in Kansai. Visitors can see items from the former business used by the Yamanaka's.

A sake brewer and local arms dealer, he traveled in secret to Nagasaki to procure 1000 Chinese guns for the Choshu Domain, which helped them win the Boshin War and eventually bring down the Tokugawa shogunate.

Located in the former residence of the salt-merchant Kumaya family, the museum features over 3000 items from the family's collection, such as paintings from Sesshu and a Siebold piano (the oldest piano in Japan).

The Masuda from Masuda in Iwami Province lived here, but it is also believed to have been a secret spy location with a tower used to monitor who entered and exited the castle town.
