This is a 6 ha (60.000sq.m.) large traditional Japanese style garden called "Chisenkai-yushiki Teien". It was constructed to celebrate the opening of Hiroshima Airport. It was designed to look like mountains/canyons of Hiroshima, and the scenery of Seto Inland Sea, and is divided into three different zones; the mountain zone that takes advantage of its nature, the country zone, and the ocean zone. 95 kinds of Japanese Irises and roughly 10,000 flower plants fully bloom in June. The number of observers is increasing year after year. In autumn, a "Maple festival" is held at the place.
