This plum festival is held every year from mid-February to the end of March. The Tsukigase Bairin (Tsukigase Plum Valley) spreads along the valley of the Satsuki River that runs through Mt. Tsukigase-oyama, and contains about 13,000 plum trees. This plum-viewing haven is said to have started when plum trees were first planted in the grounds of a temple in the area around 800 years ago. On a clear day, from the very early morning until sunrise, fog rises from Satsuki River as the air cools, creating a fantastic view. During the festival period, visitors can enjoy events, food, and other festivities amongst the seemingly endless plum blossoms.
