Chihoku Peace Park, Memorial park and cemetery in Ōbu, Japan.

Chihoku Peace Park is a memorial ground with cemetery sections and landscaped areas near Obu in Aichi Prefecture. The property includes walking routes, planted areas, and burial grounds that combine different functions on a single connected site.

Chihoku Peace Park opened in 1982 as a cemetery park, run by the Chihoku Peace Park Union, a joint body formed on 1 April 1979 by Obu, Tokai and Higashiura. The union, headed by the Tokai mayor with the Obu and Higashiura mayors as deputies, also manages the adjoining Chihoku cemetery and funeral hall.

The park serves as a place where visitors pause to remember past events and honor those commemorated here. It functions as a gathering space for memorial observances and allows people to find moments for personal reflection.

The park is reached by community buses from three directions: Obu's Fureai bus west course from JR Obu Station, Tokai's Ranran bus south route from Minami-Kagiya Station, and Ura-ra buses from Ogawa or Tatsugigaoka stations, all stopping at the park. By car it is about 1.5 km from the Higashiura-Chita interchange; Yawata-Shinden Station lies roughly 1.6 km away.

The park is run by the Chihoku Peace Park Union, a joint body formed on 1 April 1979 by Obu, Tokai and Higashiura. Its manager is the mayor of Tokai, with the mayors of Obu and Higashiura as deputies, and the assembly has seven members: two from Tokai, two from Obu and three from Higashiura.
