Onoyama Park is a large park in Naha, Okinawa, a short walk from Ouyama Park Station. It has children's play equipment, a long slide, a baseball field, tennis courts, and a regular swimming pool, with Okinawa Shrine and Gokoku Shrine next to it. A 1,060-meter loop running course with cushioning is used by residents in the morning and evening, and the park also contains a martial arts hall and an athletics stadium. There is no shade around the play equipment, making it hard to avoid the sun.
