Rikugi-en (六義園[1]) is a metropolitan park in Bunkyō-ku, Tokyo, Japan.

The founder of Mitsubishi, Iwasaki Yatarō, bought the gardens in 1878 and began to restore it.

They were specified as a special place of scenic beauty (特別名勝, tokubetsu meishō) by the Japanese government in 1953.

People over 65 pay 150 yen, and students under junior high school age (and junior high school students living or studying in the Tokyo metropolitan area) may enter for free.

For short periods during spring and autumn the cherry blossoms and autumn foliage respectively are temporarily lit up and the gardens remain open until 9 p.m.[4] Media related to Rikugi-en at Wikimedia Commons
