Dōhō Park, Urban recreational park in Ninomiya, Tsukuba, Japan.

Dōhō Park is a 20-hectare urban park in Ninomiya, Tsukuba, Ibaraki Prefecture, opened in 1980 and centred on Dōhō-numa swamp. Its facilities include a 50-metre, nine-lane solar-heated pool, an arena with 400 seats, six tennis courts, a baseball ground and a grass multipurpose field. A rubber-and-urethane paved loop of 1,050 metres circles the swamp, and the New City Memorial Hall, completed in 1976, holds an exhibition hall and a café.

The park opened in 1980 as Tsukuba was being developed into a planned science city, with green spaces built alongside the new residential districts. It was designed from the start as a place for the growing population arriving in the area.

The park sits in a neighborhood built as part of Tsukuba Science City, and it reflects the daily life of the people who grew up there. On weekend mornings, families walk along the paths, groups use the sports fields, and older residents move at a slower pace through the grounds.

The park is easy to reach on foot from the surrounding neighborhoods and has facilities for both sport and outdoor walking. Visiting on a weekday tends to be quieter, especially near the sports areas.

The swamp at the park's centre is called Dōhō-numa, and its present form is only a remnant: the former upper pond was reduced in size and the lower pond was filled in during construction of Tsukuba Science City in 1972, its site becoming Gakuen-nishi-dori and housing. A 1,050 m rubber-paved loop circles the water, now fed by rainwater and well water rather than streams.
