Otaku Battles
There are groups who dress up in camouflage clothing and run about in various settings - woods, countryside, even urban - shooting at each other with air guns. These outings are actually organized and some of the participants will own several models of air guns. They even have magazines dedicated to this hobby.
The guns used shoot soft pellets. Guns that can fire metal projectiles are illegal.
The rifles and pistols used are very realistic.
