Yoyogi Park (代々木公園, Yoyogi kōen?) is one of the largest parks in Tokyo, Japan located adjacent to Harajuku Station and Meiji Shrine in Shibuya.
What is now Yoyogi Park was the site of the first successful powered aircraft flight in Japan, on December 19, 1910, by Captain Yoshitoshi Tokugawa, after which it became an army parade ground. During the post World War II occupation, it was the site of the Washington Heights residence for U.S. officers. It was later the site for the main Olympic athletes village of the 1964 Summer Olympics and the swimming, diving, and basketball venues. The distinctive Yoyogi National Gymnasium which hosted swimming, diving, and basketball was designed by Kenzo Tange for the Olympics, and is still in use, but most of the area north of the gymnasium complex and south of Meiji Shrine was turned into a city park in 1967.
Today, the park is a popular hangout, especially on Sundays, when it is used as a gathering place for people to play music, practice martial arts, etc. The park has a bike path, a public basketball court, and bicycle rentals are available. As a consequence of Japan's long recession, there are several large, but quiet and orderly, homeless camps around the park's periphery.
