Ishikawajima Park, Urban park in Tsukuda, Japan.

Ishikawajima Park is a long, narrow municipal park in Tsukuda 2 and 3-chome, Chuo Ward, Tokyo, laid out in two levels along the Sumida River, its distributary and the Asashio Canal. It runs from Chuo Ohashi Bridge to beyond Aioi Bridge, with the upper level linked to the lower by ramps. The lower level partly floods at high tide or after heavy rain.

The park opened in April 1990 as part of the Ohkawabata River City 21 redevelopment, whose urban plan was approved in 1986 and whose construction began in 1988. The name Ishikawajima is the old Edo-period name of Tsukuda 2-chome, taken from the Ishikawa family who held this land; the shipyard founded here gave IHI its former name, Ishikawajima-Harima Heavy Industries.

The northern end of the upper level holds a plaza built in 1999 and named Pari Koen (Paris Square) after the Seine, the French river twinned with the Sumida. The name marks the river friendship rather than a city partnership, and the plaza is a paved open space at the top of the slope.

The park has two levels joined by ramps, so cyclists and wheelchair users can move between them. The lower level partly floods at high tide or after heavy rain. There are benches and toilets but no parking, vending machines or playground equipment. It is a 7-minute walk from Tsukishima Station on the Toei Oedo and Yurakucho lines.

The park's upper and lower levels are linked by ramps, so cyclists and wheelchair users can move between them without steps. The lower level floods in part at high tide or after heavy rain, while the upper north end, named Paris Square in 1999 after Tokyo's friendship-river tie with the Seine, gives a view its visitors compare to standing at a ship's bow.
