Gun laws in Japan are very strict.
Gun ownership is a privilege, not a right, and there are a lot of hoops to jump through to purchase a firearm, as well as hoops to continue jumping through afterward. The yearly gun inspection is one of them.

Every year after the hunting season all firearms owners are required to take all their firearms to the local police station for inspection. They check that the firearms have been used for their registered purpose, that no illegal modifications have been made, and we all have to be interviewed (are you a drug addict? etc).

Everything went smoothly as usual, and I cleaned the M3 and put her away till the next time we hunt (next week maybe?).

Friend of mine snapped this from the treehouse. Looks like she's got some photography skills.
