Odai Park, Urban park in Higashiura, Japan

Odai Park is a 12.1-hectare general park in Higashiura, Aichi Prefecture, opened in March 2003. It contains a medicinal plant garden with about 60 herbs and 100 medicinal trees, a pond growing the town-collected spiny water lily alongside giant and Paraguay water lilies, and a play area with slides. Cherry, plum and iris are planted on the grounds.

The park was named to honor a historical figure from the 16th century whose family played a role in the founding of Japan's major shogunate and originated from the local region. This historical connection remains central to the site's identity and significance.

The park honors a prominent historical figure whose family originated from this region, and this connection shapes how people experience the space today. Visitors can feel this heritage reflected in the garden layout and seasonal celebrations that take place here.

The park is accessible by train with a short walk or by car, making it easy to reach from the surrounding area. Visitors should wear comfortable shoes and dress appropriately for the season, as conditions vary throughout the year depending on which plants are in bloom.

At its opening in March 2003, Odai Park planted second-generation saplings of the Hiroshima bombed camphor tree and the bombed Chinese parasol tree. The Onibasu pond also grows the South American giant water lily and the Paraguay water lily alongside the native spiny water lily collected within the town.
