Kōrakuen Hall (後楽園ホール, Kōrakuen Hōru) is an arena in Bunkyo, Tokyo, Japan, which has hosted many boxing, professional wrestling and mixed martial arts matches. Part of Tokyo Dome City, it is one of Tokyo's biggest attractions. It opened on April 16, 1962 and has a capacity of approximately 1,800 people. The venue hosted the boxing events for the 1964 Summer Olympics. In the rounds of pro wrestling, it is considered as being the Madison Square Garden of puroresu, as all of Japan's largest promotions have run some of their larger shows there, much akin to the WWF/E's monthly show at MSG in the 80's. Korakuen Hall is also known for the fact that every wrestling promotion in Japan, large or small, defunct or not, has run a show there.
