I've been meaning to get some photos of Ikebukuro up, and finally did today:
All of the pictures on that page were taken on the evening of September 8th, 2006. Ikebukuro is one of the major train hubs of central Tokyo, just four stops from Shinjuku. Shinjuku is the bigger and better known of the two, but Ikebukuro has a lot to offer in the way of shopping, restaurants, movie theaters, a concert hall, etc. as well.
