This historic park, established in the 3rd year of the Taisho era, is located in the center of the urban area of Mori Town and is cherished by the town's residents as a place for relaxation and recreation. Approximately 1,000 cherry trees of 17 varieties, led by the Somei Yoshino, are planted here, and unique species such as 'Mori Komachi' can also be seen.

The 'Sakura Matsuri' (Cherry Blossom Festival) in May has been held since the 25th year of the Showa era and bustles with over 100,000 cherry blossom viewers each year. Additionally, the 'Kayabe no Kuribayashi' (Kayabe Chestnut Grove) within the park is designated as a Natural Monument of Hokkaido, preserving the appearance of a primeval forest from ancient times, and includes about 130 trees, including old ones reaching 200 years of age.
