Simple

I really like Japanese city logos.  They are simple and effective.  I really wish more designs would be this clean. 

There are some that aren't quite as good.  At times the simplification goes so far that the shape loses any kind of meaning.  For example, the logo of Osaka.

The first logo is for Fujiyoshida, the area where Mt. Fuji is located.  It's obvious and it works.  Osaka's logo, on the other hand, doesn't really really look like much of anything.  It's boring and rather uninspired.
