Japanese police are used to certain types of crime. Crimes that are common on US shores (threats, bullying, creating fake profiles to defame someone) tend to not be common in Japan, just because it isn't part of the relatively conformist Japanese mindset to be a troll [1].
Now, if someone tried smuggling or fraud, the Japanese police know exactly what to do.
[1]: Wish part of that mindset would come to the US... Conforming isn't surrender... it is being able to give up something, no matter how small, so the community around one doesn't suck as much.
The Japanese have a great deal of conformity of behavior, expressed by lots of social protocols and expectations. More than one American has gone there and learned that small gestures that seemed insignificant at the time were major faux pas. Of course anyone who visits a culture without learning about it first is leaving themselves open to such mishaps...
The Americans have a great deal of conformity of ideas and philosophies, expressed by trends, political forces and a completely homogeneous media. These are mostly failed philosophies in which fundamental assumptions are not questioned. They are designed only to produce never-ending circular debate to give the appearance of legitimacy and public involvement in major decisions.
What most Americans call "individuality" still requires a large group, an audience, to which it can be conspicuously shown off. It seldom involves anything less superficial than mannerisms or styles of dress or tastes in music. It seldom involves concerns less mundane than "what is everybody else doing?"
I would say that the Japanese notion of conformity is much less dangerous but that particular meaning is far from universal. I'm not the typical insecure "you must be a moron" Slashdotter, so I will ask instead of assuming: is what you wrote intended to encourage conformity for its own sake, or do you simply believe that a bit more would be a social improvement (or some other possibility that did not occur to me)?
As a tangent, I believe this kind of emotional immaturity, lack of desire for real meaning and preoccupation with the opinions of others (i.e. widespread childishness) is why the US federal government is so out-of-control. The power-hungry see that and say "these are not people who will realize the implications of what I am doing, and certainly aren't going to put any effort into stopping it, not as long as they're fat and entertained". It's a green light. Read about the Whiskey Rebellion and ask yourself if you think the people involved were more concerned with singers and actors than with what their government was doing.
