Kairakuen is one of the best Japanese gardens and is most famous for its over three thousand plum trees. Kairakuen is located in Mito, the capital of Ibaraki Prefecture. Kairakuen was built in 1841 by the local lord Tokugawa Nariaki. Unlike Japan's other great landscaped gardens, Kairakuen served not only for the ruling lord but it was open to the public. Kairakuen means "park to be enjoyed together."
Kairakuen is particularly beautiful during the plum blossom season, from late February through March. The garden features about 3000 trees with white, pink, and red blossoms. The Mito Plum Festival (Mito Ume Matsuri) is held annually from mid-February through the end of March. Kairakuen also features a bamboo grove, cedar woods, and the Kobuntei, a traditional Japanese house. Like the rest of the park, the Kobuntei has always been open to the public and served educational purposes.
I visited Kairakuen in the beginning of May when plum blossom season was over and there were rather big green plums. I enjoyed the blooming azalea and many other flowers. I went to Kairakuen on a rainy day, so Kobuntei was a great place to stay indoors. After my visit, the rain was over and I could enjoy walking in the garden.
