The GTMF Organizing Committee announced a second batch of five exhibitors for Game Tools & Middleware Forum 2026, bringing the total to 20 companies. ThinkingData and Yamaha Corporation join as Gold sponsors, while DynaComware, Diarkis, and Havok enter at Silver. The organizer is listed as Idea Co., Ltd. alongside CRI Middleware Co., Ltd. Seven outlets and events also join as media partners: Famitsu, 4Gamer.net, AUTOMATON, GAME Watch, Game Makers, GAME FUTURE SUMMIT, and GameBusiness.jp. GTMF 2026 runs Wednesday, December 2 at Knowledge Capital Congres Convention Center in Osaka and Tuesday, December 8 at Akihabara UDX in Tokyo, both from 9:30 to 18:30 with entry and exit permitted midway. Admission is free but advance registration is required, and an After Party at both venues will be detailed later.
The second batch brings five companies, which the organizer splits across two sponsor tiers. ThinkingData and Yamaha Corporation arrive at Gold, and DynaComware, Diarkis, and Havok arrive at Silver. The full exhibitor list runs from Pearl sponsors k-ID and Silicon Studio down through Gold names such as Audiokinetic, Khronos Group, Game Server Services, Speech Graphics, Sony, SoftBank, Hitachi Solutions Technology, Meshy AI, and IncrediBuild Japan, and Silver names including Geolocation Technology, Spark, Toshiba, and Toyo.
One point where the two reports diverge is the organizer's own name: one lists Idea Co., Ltd. and the other lists EID Inc., the same company under different labels, alongside CRI Middleware. Both also list GameBusiness.jp as a media partner, which means the outlet publishing the notice is also named in it. The 2026 edition is the 21st holding. Seminar sessions and an After Party round out the Osaka and Tokyo dates.
