Japanese Homework

One of the most interesting things about Japanese culture is the studying-in-a-restaurant-thing.

Whenever I go to McDonalds, Dennys, Mos Burger, StarBucks (where this photo was taken), I would always see students quietly studying away.

I tried to look for reasons why people do this through this search query and came up with things like...

• Able to concentrate more than being at (noisy) home.
• Lack of time so do homework during lunch or dinner.
• Can focus instead of being distracted by the computer (ero sites I'm guessing).
• More space available so don't feel cramped (like at home).
• Get to use the cool air conditioner for free.

Where do you do your homework and how much of it do you get?
BTW, if you are learning languages then you may want to have a read through some of the techniques I used to learn Japanese.
