Why do Japanese developers take so long to make a single game?

Don't you guys think Japanese developers should increase their teams then? Also is this the only reason or are there culture reasons behind it? I remember Sakurai saying that instead of finishing a game they would keep modifying it?

Well, that depends. You could also argue that having several hundred people working on one game is a bit wasteful as well. If you have so many people working on one game that it has to sell 5 million copies just to break even (not even counting advertising), you're rolling the dice with every release.
