Koishikawa Korakuen, a Japanese Garden

Koishikawa Korakuen (小石川後楽園, Koishikawa Kōrakuen) is one of Tokyo's oldest and best Japanese gardens. It was built in the early Edo Period (1600-1868) at the Tokyo residence of the Mito branch of the ruling Tokugawa family. Like its namesake in Okayama, the garden was named Korakuen after a poem encouraging a ruler to enjoy pleasure only after achieving happiness for his people. Koishikawa is the district in which the garden is located in.
