Kamogawa Sea World in Kamogawa City, Chiba Prefecture, will hold the "Kamosea Premium Plan" (鴨シープレミアムプラン) and the "Kamosea Premium Stay Plan" (鴨シープレミアム宿泊プラン) for the first time, on nine limited days in November 2026. Built around the four kinds of animals that star in the park's performances, the plans let participants join special programs after the aquarium closes.
Four Special Programs After Closing Time
The Kamosea Premium Plan includes a commemorative photo with orcas, a chance to touch belugas, and a commemorative photo with sea lions. It also includes a special lecture on the breeding of Pacific white-sided dolphins, given by a keeper. Admission on the day of the plan is included, so participants can watch the performances during the day and enjoy the experiences after the aquarium closes.
Dinner and the "Night Adventure"
After the experiences, participants head to the restaurant "Ocean," where diners can eat while looking at the orcas. Dinner combines a main plate with a buffet, so guests can enjoy the best of both at a relaxed pace.
After dinner comes the "Night Adventure," a keeper-guided walk through the aquarium at night. Participants can see the animals' quiet sleeping faces and get a sense of how they breathe and spend the night.
Staying Overnight
For visitors from far away, or anyone who wants a more relaxed trip, the Kamosea Premium Stay Plan adds a stay at Kamogawa Sea World Hotel. After the plan ends, participants return to the hotel and can spend a relaxed time there.
November, when autumn is at its deepest, is a good time for an outing, and the plans let visitors enjoy Kamogawa Sea World in a way that suits their travel style.
What the Kamosea Premium Plan Includes
Commemorative Photo with Orcas (Photo Included)
Participants can take a group commemorative photo with the orcas, which are large yet lovable.
