Gongendo Park is famous for its cherry blossoms and rapeseed scenery which attracts thousands of visitors every spring. However, in recent years the park's hydrangea have been growing in fame and popularity. Approximately 16,000 hydrangea bloom in Gongendo Park every June. They are located close to the main car park of the park. During the period of the bloom the park hosts a Hydrangea Festival.
In 2020, there was no festival due to the Coronavirus outbreak. It remains to be seen if the 2021 festival can go ahead. However, even if it doesn't, the park is still open to the public.
