Shinjuku Gyoen was constructed on the site of a private mansion belonging to a “daimyo” (feudal lord) Naito, at the Edo era (1591). The government-managed agricultural experiment station was established in 1872, and after that it became imperial estate, completed in 1906 as an imperial garden. It developed as a palace garden for international diplomacy, re-designated as a national garden after the World War Ⅱ and opened to the public.
