The Omagari fireworks display, held here annually, is one of the few national competitions where pyrotechnicians compete for the Prime Minister's Award.
The park's open design is specifically contoured to amplify the acoustics of the fireworks shells as they burst over the river.
During the winter months, the park is often covered in deep snow, transforming the athletic fields into a frozen landscape that is unusable for standard sports.
The park is situated at the confluence of several geographical features that help minimize light pollution, allowing for better visibility of the fireworks.
The embankment is part of an extensive river management system intended to prevent flooding in the Omagari district.
Omono Riverside Ryokuchi Athletic Park serves as the primary venue for the Omagari National Fireworks Competition, one of Japan's most prestigious pyrotechnic events. The park occupies a large, open stretch of land along the Omono River in Daisen, Akita Prefecture. Its geography is defined by a wide, flat embankment designed to accommodate tens of thousands of spectators during the annual summer festival. Beyond its festival role, the park features sports facilities including athletic tracks and open grass fields for local recreation. The site is engineered to manage the river's flow while providing clear, unobstructed sightlines across the water. It is a dual-use space that balances municipal athletic infrastructure with massive event-hosting capabilities.

Bring a portable folding seat or a picnic mat if visiting for a recreational afternoon, as built-in seating is scarce.
Check the river water levels before visiting during the spring thaw, as sections of the park near the water's edge may be restricted.
Wear high-SPF sunscreen and insect repellent, as the riverside location offers little natural shade and can attract midges in summer.
Visiting during the few days surrounding the annual fireworks festival without a pre-booked seat or reservation, as the entire area is restricted to ticket holders.
The park is subject to total closure and cordoning off to the public for several days in late August to facilitate the Omagari National Fireworks Competition.
Carry out all trash as there are limited public bins; keep noise levels low during non-event days to respect the quiet residential surroundings.
