Kamogawa Sea World is a premier marine theme park located in Kamogawa City, Chiba Prefecture. Its greatest draw is the opportunity to witness dynamic and powerful performances by killer whales (orca), alongside close encounters with various marine animals such as dolphins, sea lions, and beluga whales. The facility is highly regarded as an educational center where visitors can learn about the relationship between marine life and the natural environment.
Since its opening in 1973, the park has engaged in diverse activities ranging from educational programs to wildlife conservation and captive breeding research. The facility focuses heavily on environmental preservation, including the protection of marine mammals stranded along the Boso coast, the conservation of sea turtle eggs, and the preservation of habitats for rare aquatic insects. Furthermore, the park maintains strong ties with the local community, actively participating in local cultural events and safety campaigns in collaboration with government agencies, schools, and tourism associations.

The park features various exhibition areas and performance facilities tailored to different themes. The most popular attraction is the "Ocean Stadium," where the killer whale performances take place. Because water often splashes into the spectator seats, it offers an incredibly dynamic and immersive experience. Other specialized facilities include the "Surf Stadium" for dolphin shows, the "Marine Theater" for beluga whale performances, and "Rocky Stadium" for sea lion exhibitions.
The exhibition areas are also incredibly diverse. You can explore the "Eco Aquaroom," themed around the nature of the Boso Peninsula, or visit "Kurage Life," a specialized jellyfish exhibition. In "Rocky World," which recreates the natural environment of the Pacific Ocean, you can observe penguins, sea mammals, and seals. The park also features environments mimicking the Arctic and Antarctic regions, allowing visitors to feel the diversity of global ecosystems.
Kamogawa Sea World hosts various programs throughout the year. Because exhibitions and events change depending on the season, you may encounter different charms depending on when you visit. It is crucial to check the official website before your visit to confirm the daily schedule, as the main programs like the killer whale shows are held at specific times. While the daytime performances are high-energy, there are also wonderful moments to enjoy a quiet stroll through the exhibition areas.

Beyond watching animal performances, the park offers rich learning opportunities. The exhibits are designed to deepen your knowledge of marine biology and ecology. The facility also includes shops and restaurants, allowing you to enjoy a meal during your visit. A truly special experience can be found at the restaurant "Ocean" located beneath the Ocean Stadium, where you can dine while watching the killer whales swim gracefully through the water.
Located on the Boso Peninsula in Chiba, Kamogawa Sea World is surrounded by many wonderful tourist resources. The area features many hot spring (onsen) facilities and beautiful coastal landscapes. For a complete resort experience, visitors can stay at the "Kamogawa Sea World Hotel," the official hotel, which offers special benefits such as admission perks for the aquarium.
