In Japan, young people over the age of 10 but below 18 years can purchase the "10 Air Sports Gun" according to Hyperdouraku. These have a power of around 0.135j as compared to the standard 0.989j for the airsoft guns available to 18 years and above. With that power, BB weight is recommended at .12g. If you just need a cheap airsoft pistol as a prop sidearm, then you might just want to get one of these.

Tokyo Marui announce that they will releasing an Air-cocking Sig P228 Stainless Type Pistol. This means this is a springer pistol that does not require a power source to fire the 6mm BB. This will be released on the 8th of March and is priced JPY3,200 and has been cleared with the Japanese Youth Development Ordnance that it can be safely used by players aged 10 and up. Below is the rough translation of its features:

Mach Sakai finds another air cocking airsoft pistol to review in the form of the Tokyo Marui HG M92F Military Spring Cocking Airsoft Pistol. A much affordable airsoft pistol, it has full markings and comes with a 22-round capacity magazine. Not fast to shoot unless you practice hard to do quick cocking, he finds it still fun to shoot with.

Hyperdouraku goes into a review session again and this time it's the newer version of the Tanaka Works M40A1 Air (Air Cocking Airsoft Sniper Rifle) whereas before they had the shell-ejecting version. This has a new bb-feeding system with the magazine having a capacity of 27-rounds and it also has a top Picatinny rail for mounting optics and the bolt handle has been designed not to hit the scope when it's flipped up.
