Ikebukuro Station is a huge and bustling railway junction surrounded by tons of food, and shopping. The area is also well known for some of the best Ramen in the city.
There are two department stores in Ikebukuro: Seibu and Tobu. Seibu means "Western," and Tobu means "Eastern." But actually Seibu at East side and Tobu at West side of the station. Don't ask me why...
