Ikebukuro is an area of massive development. Several thousand tenants occupy two giant department stores and shopping malls, where all sorts of shopping and gourmet foods can be enjoyed. The 60-story building at the east entrance of the station, Sunshine City, is a landmark within Ikebukuro and features an aquarium, planetarium, theme park as well as an observation platform. The popular name for the western side of this area is "Otome Road" (Maiden Road) and there are many shops selling products related to anime with a female theme. It has rapidly become the worldwide headquarters for ‘otaku’ or geek culture.
