Founded in 1950 by the former Lord Shōnai in order to preserve local culture, this museum features Sakai-family artefacts, two Meiji-era buildings, a traditional storehouse and a kabuto-zukuri (farmhouse with a thatched roof shaped like a samurai helmet). The museum is on the southwest corner of Tsuruoka-kōen, the site of the former Sakai castle.
