It is one of the subcenters, and together with Shinjuku and Shibuya, forms a lively shopping district and entertainment district. There used to be many ponds around here, and until the latter half of the 1990s, in the former Ikebukuro Park, south of the west exit of Ikebukuro Station, it is said to be a remnant of Maruike, which was a famous place for fireflies and the moon during the Edo period. There was Koike. This Maruike is the water source pond of the Tsurumaki River, and the name of the place is said to be derived from the fact that the area was a depression and the terrain was like a bag. > spot in Tokyo stocks
