they're violent, but not in a bad way. they hit a lot...smacking someone's head or hitting them with plastic bats, air bats, ect. is completely normal. ahahahaha.
but they're not social in public. you rarely see them saying "hi" to someone walking down the street. they mind their own business, so they're very quiet in public.
as for guns, they rarely need them.
the truth is, compared to the states, there's a lot more mature teens in japan then there in in the states. a good example are fireworks. illegal in the states, but legal in japan. why? most teens don't goof around with them like idiots. another example is alcohol and cigarettes. you can buy them from vending machines. why? because most teens know better than to smoke or get drunk.
those weren't really "mature" or "immature" examples, but you get the point.
