The Tokyo Game Show, commonly known as TGS, is a video game expo / convention held annually in the Makuhari Messe, in Chiba, Japan. It is presented by the Computer Entertainment Supplier's Association (CESA) and the Nikkei Business Publications, Inc. It is used by many international video game developers to show off their upcoming games and game-related hardware, though the main focus is on the Japanese market rather than overseas.
Like Gamescom, the Tokyo Game Show allows the general public to attend during the final two days. The most recent show was held in 2010 from September 16th to the 19th, and was hosted by Computer Entertainment Supplier's Association. The 2011 Tokyo Game Show was held from September 15th to the 18th.
