Airsoft Toothbrush (VIDEO)
Yes, That is Correct:
In the Mostly Accurate Stereotypes of the World Handbook (really wish that was a thing), modern Japanese people aren't normally correlated with the made-for-anti-terrorism Glock 18c fully automatic handgun, so this video can seem a little unsettling in the first few frames. But don't worry, laugh yourself over that fairly quickly.
And about that, see, cops have guns here in Japan, and while it is legal, possession by private citizens is rare (requires navigating a nearly impenetrable licensing process). But, Airsoft is hugely popular, and shops stocking full-on arsenals & ammo are relatively easy to find.
Airsoft even gets folded into an otaku cocktail at places like Akihabara's combined maid cafe/shooting range, Friendly Fire.
There is pretty much zero information available on the guy who made this video, but we do know this isn't the first time tokioFN has explored compressed-air-powered, pellet gun-based oral hygiene. Yeah, there are more - with larger guns, too.
