豊島区立元池袋史跡公園, Public park in Toshima, Tokyo, Japan

Toshima Motoikebukuro Park is a small historic-site park in Nishi-Ikebukuro, Toshima, Tokyo, opened in April 1998. It has a small fountain marking the former Maru Pond, whose water was the source of the Tsurumaki River, and a monument commemorating the founding site of Seikei Gakuen. The grounds are lit at night, and there are no barriers and few benches.

The current park opened in April 1998 as a historic-site park. It replaced the former Motoikebukuro Park, which stood on the site of today's Ikebukuro Duplex Tower and was closed after a land swap for sewer works; its Maruike pond, the source of the Tsurumakawa, was completely filled in. The new park keeps the memory of that pond, from which the name Ikebukuro derives. A monument also marks the founding site of Seikei Gakuen.

The park marks the source of the former Maruike pond, from which the name Ikebukuro derives; a small fountain recalls the pond that was filled in. A monument on the grounds commemorates Keio Gijuku's founding site. The grounds are lit at night, giving them the look of an ornamental structure rather than a park.

The park has no barriers and few benches, so it suits a short stop rather than a long stay. The Metropolitan Plaza to the east brings heavy traffic on the surrounding streets. For sitting and lingering, the larger Ikebukuro West Gate Park to the north is better suited.

The park's small fountain marks the site of the former Maruike pond, the source of the Tsurumakawa river and the origin of the name Ikebukuro. The pond was filled in during sewer works and the old park gave way to the Ikebukuro Duplex Tower; this historic-site park opened in April 1998 to keep the memory.
