土岐氏
In 1912, a former samurai in the service of the Toki clan, Kume Tamenosuke, purchased the castle site, and he donated it to the town of Numata in 1926 for use as a park. The park contains the Ubukata House, an Edo period structure that was once used as a pharmacy in the Numata castle town. The structure is an Important Cultural Property and serves as a local history museum. It also contains a scale model of Numata Castle under the Sanada.
