Kairakuen
Kaiyakuen is a Daimyo garden in Mito, Ibaraki, Japan. It is one of the three gardens in Japan alongside Korakuen in Okayama City and Kenrokuen in Kanazawa City. In July 1999, the name was merged into a park named Kairakuen. The park is adjacent to the city and covers an area of 3 million square meters, the second largest in the world after New York City's Central Park. It is now managed by Ibaraki Prefecture.
