There are very strict gun control laws in Japan to restrict the mechanisms and material of modelguns so that modelguns appeared in the Japanese market are safe and cannot be converted into anything that can shoot live cartridges or projectiles. Their high resemblance to the real guns and complete safeness make them very attractive to many gun enthusiasts, especially in those countries with very strict real gun control. Best of all, they are only a fraction of cost to the real ones and some even replicate the very rare out-of-reach original models. Modelguns are legal to own in many countries and don't require license for ownership. Having said that, it is recommended that the respective law regarding imitated firearms of individual country should be consulted. Modelguns are not illegal in some countries but it is very hard to pass their Customs. Whilst they are free to import and own in some other countries but the cap is illegal to sell and own there. They may also have trademark infringement issues in some countries.
