Kumagaya Sakura Sports Park, A sports park in Kumagaya, Saitama Prefecture.

Kumagaya Sakura Sports Park is a city-run sports park in Kojima, Kumagaya, with an athletics stadium that has a natural grass pitch and a clay track, a baseball stadium with 24,500 seats, a second and third baseball ground, tennis courts, an archery range, a sumo ring, and the indoor pool Aquapia.

The park's baseball ground replaced the former Kumagaya Municipal Stadium, whose site was redeveloped as the Isecho Fureai Park (South Ground). In April 2024 the onsen company K.K. Onsen Dojo acquired naming rights, renaming the ballpark Ofuro Cafe Hareniwa Stadium Kumagaya (Haresta Kumagaya) until March 2027. The outdoor pool, opened on 17 July 1971, closed permanently after years of closure and ageing.

The nickname Kumagaya Sakura Sports Park was adopted in April 2009, when the city handed management to a designated operator. The name is an official nickname; the formal name remains Kumagaya Undo Koen. The park's athletics stadium hosts the annual Kumagaya Sakura Marathon.

The park is easily accessible by train to Kumagaya Station, from which buses or a short walk will get you there. Visitors can bring their own food and drinks, though restrictions apply during sporting events, and refreshments are available on-site.

The baseball ground, commonly called Kumagaya Park Stadium, has foul territory and stands so narrow, with no protective net around the perimeter, that more than half of foul balls leave the site. Since April 2024 it has been named Ofuro Café Hareniwa Stadium Kumagaya under a naming-rights deal with Onsen Dojo running to March 2027.
