Koishikawa Korakuen is located north of the Imperial Palace in the Koishikawa District and was first built in the early Edo Period (1603-1867). It was built at the residence of the Mito Clan, a branch of the Tokugawa family, in Tokyo. Like the Korakuen in Okayama, the name was taken from a poem that encourages the happiness of the people first, which will allow the leaders to enjoy all the garden has to offer. The garden is most attractive in late November to early December when the autumn colors settle in. It would also be good to be at the Koishikawa Korakuen for the plum season, which is from mid-February to March, and the cherry blossom season. At the entrance are several weeping cherry trees that bloom earlier than the other varieties.
