On 20 May 1963, Emperor Shōwa was invited to the park to attend the 14th Annual Tree Planting Event and National Greening Convention. The rows of cherry blossom trees in the park were planted in order to commemorate the tree-planting by the emperor and empress. Additionally, a stone monument was erected in honor of "His Majesty the Emperor's Tree-Planting Ceremony". From 2012 until 2015, the park served as a venue for the AomoriRock Festival. The event included performances by hip-hop artists, Japanese idol groups, and professional wrestlers. The park will be one of the many sources of the Paralympic flame that will be collected from around Aomori Prefecture at the Sannai-Maruyama site in Aomori from where the collected flame will be sent to the New National Stadium in Tokyo as part of 2020 Summer Paralympics torch relay. The Scallop Festival, sponsored by the Hiranai Fisherman's Cooperative Association and the town, is held in the park each September.
