DVD screening room.
There is a service in Japan that allows you to rent a private room to watch DVDs. It's like an internet cafe. When you rent one of these private rooms, you can watch a variety of videos using DVDs and other media. You can watch anything from movies to pornography if you want to.
If you walk down a back alley in Japan, you will always see this glittering sign of a DVD screening room. If you are ever in Japan, I highly recommend you stop by.
