night life

Japan is a great place to enjoy not only sightseeing but night life. Tokyo has Roppongi, Shinjuku, and Shibuya, and Osaka has Namba and Umeda. You don't need to look into the guidebooks, just go out on the street and can find bars and clubs which are open until late. It is safe and cheap in general, so these places are getting more popular than ever with young tourists.
