Tokyo Game Show 2026 runs from Sept. 17 to 21 at Makuhari Messe in Chiba Prefecture, Japan, in the event's largest edition to date. Organizer CESA said 1,138 companies from 53 countries are participating across 3,946 booths, with attendance expected to reach about 300,000. Overseas exhibitors number 598, exceeding the 540 Japanese companies taking part. Nexon, NCSoft, Netmarble and Smilegate are among the South Korean publishers using TGS to promote anime-style and subculture games, reflecting a broader push into Japan's $11 billion mobile in-app purchase market. The event's growing importance is sharpening concerns about G-Star, South Korea's November game exhibition, as domestic publishers increasingly choose overseas showcases for new-title debuts.
