11 Naito-machi, Shinjuku 160-0014 Tokyo Prefecture

Shinjuku Gyoen was constructed on the site of a private mansion belonging to Lord Naito, a "daimyo" (feudal lord) of the Edo era. Completed in 1906 as an imperial garden, it was re-designated as a national garden after the Second World War and opened to the public. With 58.3 ha(144 acres) in size and a circumference of 3.5 km, it blends three distinct styles, Formal Garden, Landscape Garden and Japanese Traditional Garden, and is considered to be one of the most important gardens from the Meiji era.
