Shinjuku Gyo-en is a large park and garden in Shinjuku and Shibuya, Tokyo, Japan. It was originally a residence of the Naitō family in the Edo period. Afterwards, it became a garden under the management of the Imperial Household Agency of Japan. It is now a national park under the jurisdiction of the Ministry of the Environment.
The garden, which is 58.3 hectares in area with a circumference of 3.5 km, blends three distinct styles: a French Formal and English Landscape in the north and to the south a Japanese traditional.
A traditional Japanese tea house can be found within the gardens. The garden is a favourite hanami (cherry-blossom viewing) spot, and large crowds can be present during cherry blossom season.
