Largest in Okinawa! Kaiyohaku Park Fireworks 2026 Guide

As the short rainy season ends and midsummer arrives, Okinawa Main Island gears up for one of its biggest seasonal highlights. On July 4, 2026 (Saturday), the 48th Kaiyohaku Park Summer Festival (48th Kaiyohaku Churaumi Fireworks) will be held at Emerald Beach within the State-run Okinawa Memorial Park (Kaiyohaku Park) in Motobu Town, Okinawa.

As one of the largest fireworks festivals in Okinawa, launching approximately 10,000 fireworks over the East China Sea, this event attracts both locals and tourists. In this comprehensive guide, we explain the history, highlights, ticket information, and crucial access tips to beat the massive traffic congestion, alongside a comparative look at other major fireworks festivals held in Japan on the same day.

History of Kaiyohaku Park Summer Festival

The roots of this festival trace back to the Okinawa International Ocean Exposition (Okinawa Ocean Expo) held in 1975 to commemorate Okinawa's reversion to Japan. The site of this world expo was later developed into the State-run Okinawa Memorial Park, which now houses the famous Okinawa Churaumi Aquarium.

After the expo ended, the festival was established to boost local tourism and preserve the memories of the historic event. While early festivals focused on beach games and live music, the evening fireworks display grew in size over the decades. Today, it is widely considered the official launch of the Okinawan summer, celebrating its 48th edition this year.

Key Highlights of the 2026 Churaumi Fireworks

Main highlights of the festival on July 4:

1. Over 10,000 Fireworks (Okinawa's Largest Scale)
Approximately 10,000 fireworks will be launched non-stop over a one-hour period. The program features state-of-the-art designs, including special message fireworks and musical Starmines synchronized with sound.

2. Sunset and Ocean Backdrop
Emerald Beach is famous for its coral sand. The show begins right after sunset, with the silhouette of Iejima Island's Mount Gusuku visible across the sea. The reflection of large firework flowers over the dark ocean creates a spectacular view unique to this tropical location.

3. Fully Ticketed Beach Area
To prevent overcrowding and ensure safety, the Emerald Beach viewing zone is fully ticketed. Only visitors with pre-purchased tickets can enter the beach, providing a spacious and relaxed environment to enjoy the show.

Access and Traffic Congestion Tips

Motobu Town is located in northern Okinawa, about 1.5 to 2 hours from Naha via the highway. On the day of the event, major roads will face severe gridlocks.

Official Bus Tours (Highly Recommended)
We strongly advise booking round-trip spectator bus tours departing from Naha or central Okinawa. Tour buses have dedicated route access and parking, saving you from driving stress and traffic delays.

By Car (Rental Car)
If you must drive, please note the following:

• Arrive in the morning: Park parking lots (free, approx. 1,900 spaces) fill up by 10:00–11:00 AM. Arriving early to secure a spot is essential.
• Expect delays: Leaving the parking lot after 21:00 can take 1–2 hours, followed by a 3+ hour traffic jam to Naha. Ensure you have water, snacks, and a full phone battery.
