Korakuen Hall (Japanese: 後楽園ホール, Hepburn: Kōrakuen Hōru) is a sports arena in Bunkyo, Tokyo, Japan, which has hosted boxing, professional wrestling, kickboxing, mixed martial arts and Lethwei matches.

[4] On October 27, 2016, the hall became the chosen venue for the International Lethwei Federation Japan.

[5] The Lethwei Grand Prix Japan 2016 was the first event of the promotion held at the venue.

After the construction completed, the Tokyo Dome Corporation, which owns the original Korakuen Hall as well as the Tokyo Dome, would continue to rent out the original Korakuen Hall, lowering rental prices (currently it costs 1,500,000 Yen to rent) to allowing smaller promotions to use the building on a regular basis.

Although most of the sporting events take place at the Tokyo Dome, the JCB Hall is considered one of the primary spots in Tokyo Dome City for smaller scale sporting events, like boxing, pro-wrestling, Lethwei and mixed martial arts.
