Opened in 1989, Kasai Rinkai Park (¼ÕCö, Kasai Rinkai Kōen) is the largest park in central Tokyo, located just across the Edogawa River from Tokyo Disney Resort. It was built on reclaimed land and developed in an effort to restore and preserve natural Tokyo Bay habitat.
The park offers a nice break from the surrounding cityscapes and has a number of walking trails that crisscross the gardens, lawns and beaches. In addition, the park features an aquarium, a ferris wheel, a seabird sanctuary and an observation building.
Near the center of the park is the Tokyo Sealife Aquarium. The aquarium's main tank has a viewing area in its center that immerses you in the middle of a school of yellowfin tuna and bonito. The aquarium also has good penguin and seabird exhibits.
The park's most visible landmark is the Diamond and Flowers Ferris Wheel, named after its light shows that resemble sparkling diamonds or flowers. At 117 meter tall it is the second tallest ferris wheel in Japan and offers views of Tokyo Bay, Tokyo Disney Resorts and as far away as Mt. Fuji.
In line with the park's goal as a bay habitat preserve, nearly a third of the park is designated as a Sea Bird Sanctuary. Bird lovers and photographers are free to roam the area, except the marsh areas which are restricted. The Sea Bird Center has information on the local birds.
