In Japan, both genders tend to comport themselves in a manner that would be considered somewhat feminine and timid by Western standards, as that is what is considered “cool”.

On a train, a group of teenagers will often sound like a cacophony of hushed tones, almost whispers, interrupted by explosions of boyish grunts and feminine chirps.

There are large constraints placed on Japanese citizens through societal pressure, so even the teenage rebellion tends to be much more restrained.

A lot of Japanese teenage boys walk around in a daze with their eyes glued to their phones, playing games. This is even more common amongst what is termed as Hikikomori in Japan, which is roughly equivalent to western NEETs. There’s almost no sense of danger in the entire country, so they can kind of sleep walk while out and about.
I’ve occasionally come across “hoodlums” in less populated areas of Tokyo, where some street racing takes place, but it’s not common. It’s inevitable in any society for the “boring” areas to produce relatively anti-social behavior, even in a country as safe as Japan.

Underage drinking is common place, and Japanese of most demographics will drink until they literally can’t stand up and are covered in puke. Many international bars, particularly around the foreign military bases, won’t even let in Japanese customers because they lack normal restraints seen with other nationalities. Young Japanese youths can often be seen sprawled along the street.
Teenagers don’t spontaneously dance, if they do, it’s usually in a group formation. As a DJ in the Roppongi area of Tokyo, it was always frustrating when entertaining a group of Japanese youths because they would never dance, they would always sit and talk. At clubs, it’s often hard to mingle with groups of women as the entire club will coalesce into one big dancing organism.
