Dojiyama Park, Public park and museum in Nishiwaki, Japan.

Dojiyama Park is an urban park on Mount Dojiyama (96.7 m) in Nishiwaki, Hyogo Prefecture. It has walking paths, an observation deck overlooking the city, a gazebo, a lawn plaza, an outdoor stage, playground equipment including a slide, a bird cage, an artificial pond and public toilets. The Nishiwaki City General Citizen Center and the Nishiwaki City Museum of Local History stand within the grounds.

Dojiyama Park was laid out from 1910 on the 96.7 m hill of the same name in Nishiwaki. It later fell into neglect and was redeveloped from 1971 into its present form, with the general citizen centre and the local history museum added on the grounds.

The park's name comes from Dojiyama, the 96.7 m hill it occupies. Every August the "Heso no Nishiwaki Textile Festival" is held in the Omatsuri Hiroba hall inside the adjacent General Citizen Center. The Nishiwaki City Museum in the same complex displays the history of Banshu weaving and old farm tools.

The park is easy to reach through the main entrance near Nishiwaki City General Citizen Center. Visitors can explore both outdoor grounds and indoor museum spaces in one visit, and comfortable shoes help for walking the paths.

Inside the park stands a Foucault pendulum installation that makes Earth's rotation visible through its continuous motion. This physical demonstration is a rare feature found at only a handful of public locations worldwide.
