Kairakuen is classified as Daimyō garden[大名庭園（だいみょうていえん）] which is the Japanese gardens made by Daimyō[大名（だいみょう）](feudal lord). That was founded by the 9th lord of Mito Domain, Nariaki Tokugawa[徳川斉昭（とくがわなりあき）] in 1842. Especially, a rest house in the garden, Kōbuntei[好文亭（こうぶんてい）] was designed by Nariaki himself and it is said that he held the party of Waka[和歌（わか）](Japanese poetry) there.
The name "Kairakuen" derives from words by a Chinese philosopher, Mencius[孟子], "古の人は民と偕に楽しむ、故に能く楽しむなり(The governors would enjoy together with people, therefore they could have a lot of fun.)".
The garden was built on a hill with the view of the Lake Senba-ko[千波湖（せんばこ）]. So, you can enjoy the large garden surrounded by nature with the superb view of the lake.
