Kōraku-en (後楽園 Kōrakuen) is a Japanese garden located in Okayama, Okayama Prefecture. It is one of the Three Great Gardens of Japan, along with Kenroku-en and Kairaku-en. Korakuen was built in 1700 by Ikeda Tsunamasa, lord of Okayama. The garden reached its modern form in 1863. It features a central pond called Sawa-no-ike (Marsh Pond), which contains three islands purported to replicate the scenery around Lake Biwa near Kyoto. Okayama Castle can be viewed from here.
