Ikebukuro is yet another large entertainment and commercial district of Tokyo. Ikebukuro JR Station is the 2nd busiest in Tokyo (1st is Shinjuku Station) and it’s subway station is the busiest in Tokyo. It is estimated that about 1 million people pass through Ikebukuro on a normal day. There are what seem to be an endless amount of shops and restaurants in Ikebukuro and while it is an interesting place, I recommend checking out Shibuya and/or Shinjuku first. If you still need more of an urban fix and have time, then you should head over to Ikebukuro. To be honest, it doesn’t feel too different from those places except for maybe a little older; however, there is another reason why you might want to go to Ikebukuro….
