Osaka Water Park, opened on July 20, 1990, also known as Kaiyukan Aquarium, is one of the most popular water parks in Japan and one of the largest indoor aquariums in the world. Located in the city of Osaka, this park offers an immersive marine life experience for visitors of all ages.

The water park is located in Tempozan Port, in an area known as Kaiyukan Wharf. It is easily accessible by public transportation from downtown Osaka. Once inside, visitors are invited to explore the various marine habitats presented in the park through a series of tanks and exhibits.

The main tank is located in the center of the park and is accessible via a spiral staircase that surrounds the tank. Visitors can see more than 580 aquatic species including whale sharks, moon fish and other fish up close while walking around the park.

Osaka Water Park also features several other marine habitats, including a giant kelp forest, a mangrove area, a coral reef, a penguin colony, and a marine life-themed children’s play area. Each of these exhibits is designed to be both educational and interactive, offering visitors the opportunity to experience marine life up close.

In addition to the exhibits, Osaka Water Park also offers a variety of activities and shows, such as shark feedings, dolphin and seal shows, and virtual reality experiences that allow visitors to swim with virtual whales and dolphins.
