FLCL, I suppose.
Don't get me wrong, it's insane. Like, ridiculously insane. But it's good, and is sort of what you're looking for. It's very cartoony, yet the characters are realistic and believable at the same time. Imagine Yellow Submarine meets The Catcher in the Rye. It's a look at growing up and how it sucks, told via giant robot fights, aliens, and bass guitars. The setting is a somewhat realistic factory town, where "nothing amazing ever happens, and everything is normal", according to the main character, which fits your criteria.
It's very, very Japanese, but it's also emotionally affecting in a way that's hard to describe. Go ahead and watch it.
