Izushi Karō Yashiki, Historic samurai residence in Izushi, Japan.

Izushi Karō Yashiki is a historic samurai residence in Izushi with traditional Japanese construction and a two-story structure. The upper floor has lower ceilings and displays the architectural choices that supported the household's functions and security needs.

The residence stands on the site of the Edo-period mansion of Sengoku Sakyo, a central figure in the Sengoku Sōdō, a dispute within the Izushi domain. The present building, facing the Uchimachi-dōri once reserved for senior samurai near the inner moat of Izushi Castle, now serves as a museum of the Izushi domain.

The house is also called Sakyō Yashiki, after Sengoku Sakyō, a central figure in the Sengoku disturbance, whose residence once stood on this site. Its displays include materials on that dispute and daimyo procession equipment of the Izushi domain, designated intangible cultural property. The Itō Kiyonaga Memorial Hall adjoins it on the same grounds.

The museum is open from 9:00 to 17:00, with last entry at 16:30, and closes only on 31 December and 1 January. From Toyooka Station on the San'in Line or the Kyoto Tango Railway, take a Zentan Bus bound for Izushi (about 30 minutes) and walk 5 minutes from the terminus. The house faces Uchimachi-dori near the inner moat of Izushi Castle.

The building contains hidden staircases and intentionally low ceilings on the second floor, which were designed to limit sword movements during armed conflicts. This careful security design shows how architecture served combat readiness.
