Kaiyukan
Celebrating its 35th anniversary in 2025, this aquarium is located in Osaka. The aquarium, which recreates the natural environment surrounding the Pacific Ocean, is home to a total of 620 species and 30,000 living things.
Osaka Aquarium Kaiyukan is located near the Tempozan Ferris Wheel and is a good backup plan for a rainy day. The transparent tunnel inside is very distinctive, allowing visitors to walk through the tank and see various marine animals up close. Through the clear glass, you can watch colorful tropical fish, rays, and more swimming beside you and overhead, as if you were really under the sea. The lights inside the tunnel reflect off the water, creating a dreamy and mysterious atmosphere.
