All-Day Entertainment at Sea Paradise
Yokohama Hakkeijima Sea Paradise features four themed aquariums, thrill rides and family attractions, restaurants, shops, and a hotel — everything needed for a full day out. With the early bird passes, visitors can explore the park from morning to night throughout summer and Silver Week.
New Area Opening August 1: OTO-RACTION PARK
On August 1, 2026, a section of PleasureLand — the park's main attractions zone — will be reimagined as "OTO-RACTION PARK," a new area blending attractions, AI, and music. Visitors can scan a QR code at each attraction to input their current mood; the AI then analyzes that input alongside real-time data such as weather and time of day to select music that perfectly matches the moment.
The area's concept centers on three attractions: "SONIC TUNE!" (swinging/tilting), "ROCKY EAGLE" (height), and "Sound Wave" (rotation, opening in autumn 2026). Each attraction is equipped with audio systems, and the AI selects from POPS, EDM, and ROCK-style tracks to create a festival-like atmosphere across the entire zone, right by the sea.
SONIC TUNE!
"SONIC TUNE!" is a disc-type ride that spins while swinging dynamically up and down. Positioned at the center of OTO-RACTION PARK, it dazzles with lighting installed on its rails and audio system, setting the festival mood for the whole area. Riders can feel the thrill of centrifugal force, tilting, and swinging along to AI-selected EDM beats.
Opening: August 1, 2026 (Saturday)
Price: 1,000 yen (also available with One-Day Pass, PleasureLand Pass, or Sea Paradise Premium Pass, including with the early bird campaign tickets)
Duration: Approximately 2 minutes
Capacity: 40 riders
Height restriction: 120 cm and above
Age restriction: Elementary school age and above, up to age 64
ROCKY EAGLE
"ROCKY EAGLE" is a newly renamed version of the former "Flight Eagle," rebranded from August 1, 2026 to fit the OTO-RACTION PARK theme. Riders board an eagle-shaped gondola that ascends 10 meters into the air, accompanied by AI-selected ROCK-style music. At the peak, the gondola rotates 360 degrees, offering panoramic views of the ocean and the OTO-RACTION PARK below.
Opening: August 1, 2026 (Saturday)
Price: 500 yen (also available with One-Day Pass, PleasureLand Pass, or Sea Paradise Premium Pass, including with the early bird campaign tickets)
Duration: Approximately 2 minutes
Capacity: 8 two-person gondolas (up to 16 riders)

Hanabi Symphonia: Fireworks and Live Entertainment

Held at the boardwalk area of Yokohama Hakkeijima Sea Paradise, the display paints both the night sky and the sea surface with vivid color.

LIGHTIA: Immersive Dolphin Night Performance
"LIGHTIA 七色のキセキ" (LIGHTIA: Rainbow Miracle) is a dolphin night performance featuring synchronized visuals, light, sound, and fountains. The show tells an epic story of dolphins traveling through past, present, and future — exploring the birth of life, history, and connection — building toward a "miracle flower" that bridges life's harmony and the hope of the future.
Dolphins, trainers, and visual effects form a synchronized triangle, delivering a breathtaking 20-minute experience immersed in color and light.
