RAZBAM JAPAN showcased its home cockpit system, "ZERO-SIM," at Tokyo Game Show 2026, and jointly exhibited an F-35 mixed reality simulator for military use with Czech manufacturer Vrgineers. Both devices were available for on-site trials.
RAZBAM JAPAN is the Japanese subsidiary of RAZBAM, which provides third-party aircraft expansion modules for Digital Combat Simulator World (DCS World). The Japanese company's business also includes VR/MR equipment, cockpit hardware, and配套 computers for both general consumers and professionals, as well as 3D model design and development, event services, and equipment rentals. The booth also displayed exhibits made from actual equipment used in F-15 fighter jets for visitors to view and photograph.
ZERO-SIM offers semi-custom home cockpit setups depending on installation space and intended use, with prices starting around 2 million yen, varying by configuration. On-site demonstrations featured Type B (airliner layout) and Type F (fighter jet layout). The Type F experience used Microsoft Flight Simulator 12 and basically lacked combat simulation features found in Digital Combat Simulator World.
The booth also offered a helicopter simulation experience using "portable trainers," similar to those exhibited at Tokyo Game Show 2023. There were queues of visitors waiting to try the ZERO-SIM experience area.
Developed by Vrgineers, the F-35 simulator uses MR (Mixed Reality) technology. When wearing the headset, users can see both the real cockpit equipment and their own hands and feet, as well as synthetic virtual scenery and onboard system displays. Physical panels, switches, and touchscreens are operational and provide corresponding feedback within the simulator; scenarios such as placing a map in the leg pocket of the flight suit can also be replicated.
The system supports head tracking, simulating the 360-degree field of view provided by the F-35's Helmet Mounted Display System (HMDS) and Distributed Aperture System (DAS). Users can check flight information while turning their heads and see the ground below, which would normally be obscured by the cockpit and airframe, via the DAS feed. A monitor in front of the cockpit allows spectators to watch a processed version of the user's perspective in real time, which does not appear in the headset display.
A "command center" consisting of multiple monitors was set up next to the cockpit. Booth staff explained that this setup is mainly used for monitoring operations and configuring simulation scenarios, including adjusting airspace, weather conditions, and targets. During the live demonstration, staff added drone targets via the command center, which then appeared in the cockpit system for users to lock onto and simulate missile launches.
The target customers for this F-35 simulator are the militaries of nations equipped with the F-35. Unlike the ZERO-SIM sold to home users, there are currently no plans to sell it to the civilian market.
