FlyStation Japan, the first vertical wind tunnel in the country, is a debut project by Tunnel Tech. It has gained recognition as the fastest, quietest, and most powerful wind tunnel, meeting strict local safety and earthquake resistance standards and setting a new quality benchmark in the indoor skydiving industry.

Low noise emissions allowed it to be situated within just 30 meters from a residential building. The wind tunnel features a 4.5m-diameter flight chamber. A distinctive glass floor between 2 levels of 4m glass provides spectators access to the flight chamber at the start of diffusing section and a unique perspective on the flights.
