Located in Ibaraki Prefecture, this Japanese garden has over 3,000 plum trees making it a popular spot during plum blossom season, which usually takes place in late February and March. The park was built in 1841 by the local lord Tokugawa Nariaki. Kairaku-en roughly translates to "A park to be enjoyed together". As the name suggests, the garden served not only for the enjoyment of the lord but was open to the public. Along with Kenroku-en and Koraku-en, it is considered one of the Three Great Gardens of Japan. Besides the plum tree forest, Kairaku-en also features a bamboo grove, cedar woods and the Kobuntei, a traditional Japanese style building.
