To start off the discussions, I've included some pictures:
A capsule hotel that I stayed in. Yup, you sleep in that little cubby. It's like sleeping in a plastic coffin. The capsules are stacked on top of each other and beside each other. A typical hotel can hold 500-700 people. The cubby includes A/C, light, TV, radio, and some with a small sink.

Arcade games. This game has been out for little bit now in Japan. It utilizes a gaming card (such as Dragonball, Pokemon, etc.). The gamer moves the cards around on the board and then switches cards for different attacks. This particular arcade involves an army. Others use Gundam. When you are done with the game, simply press the button and the game saves onto a card so you pickup where you left off next time. No more starting from the beginning with Arcade games.

A typical meal. Here's a typical meal that I eat home. Bachelors rarely cook in Japan. Instead, we tend to buy a prepared meal at the supermarket. Yup, fresh sushi at the supermarket.

I'll post more pictures if people are interested.
