Kamogawa Sea World (Kamogawa City, Chiba Prefecture) is set to run its "Mansen Taiken" (Full Experience) program over 12 days in May 2026. Running since 2007, the program lets participants join five distinct animal encounter activities in a single day, including a handshake with an orca — a rare chance not available during regular admission.
The plan includes admission to the aquarium, a reserved nearby parking space (parking fee of ¥1,200 separately required), lunch at the on-site restaurant "Ocean," and an original muffler towel as a participation gift. A "Mansen Stay Plan" combining the program with a stay at Kamogawa Sea World Hotel is also available, catering to visitors coming from farther away.
The 5 Programs
Orca Handshake


A close-up encounter with the orca, guided by a keeper, where participants can observe the animal at close range and shake hands with it. This is an experience unique to Kamogawa Sea World.
Beluga Touch and Feeding (with commemorative photo)


Participants touch the melon (forehead area) of the all-white belugas while a photographer captures the moment for a commemorative photo. Feeding is also included.
Dolphin Sign Training and Handshake


With guidance from a keeper, participants give hand signals to dolphins, prompting behaviors such as jumping, spinning, and shaking hands — providing an up-close interaction that is not possible during regular shows.
Tropical Island Backstage Tour (machine room, loading entrance, etc.)


A guided tour of the Tropical Island backstage area, which is off-limits to regular visitors. Participants learn about the aquarium's water systems and how fish are transported.
Ray and Shark Feeding


Feeding rays and sharks in the Eco Aqua Loam offshore tank, using a feeding stick method known as "skewer feeding."
