Whilst there is a KWC Taurus PT 24/7 CO2 NBB airsoft pistol, there is also a springer version that Mach Sakai checks out in this video. This is licensed by Cybergun and it has a metal slide with a reinforced polymer frame. It usually is 320fps but this should meet the Japanese regulations at a maximum of .98j. It has a accessory under rail and rubberised ergonomic grip.
