After passing through the "Aqua Gate," a tunnel-shaped aquarium where tropical fish swim, visitors can take an escalator up to the 8th floor and walk down a slope to see various creatures in a large aquarium. Each of the aquariums is a sight to behold, including the“Antarctica" with its penguins, the "Tasman Sea," where you will be welcomed by Pacific white-sided dolphin, The "Great Barrier Reef," where colorful fishes swim around, and the "Coast of Chile," where you will be amazed by the sight of sardines swimming in schools in one direction.

The main attraction is the "Pacific Ocean” tank, where whale sharks and other large sharks and rays live together. With a depth of 9 meters, a maximum length of 34 meters, and a water volume of 5,400 tons, this huge tank will give you a feeling of being under the sea as you watch the fishes swim by. The new "Jellyfish" area is also popular, where you can be healed by the graceful swaying jellyfishes in the space that looks like a galaxy.

You can enter the aquarium as many times as you like on the same day by completing the re-entry procedure. If you enter after 5:00 p.m. The lighting is a little darker and the atmosphere is more romantic. You can also take a peek at the night life of the fish, such as those that are active during the day but are more relaxed.

    Osaka Aquarium Kaiyukan is one of the attractions in Osaka that's well worth adding to your itinerary. Before even going inside, I was drawn in by the enormous building. The aquarium is very large, and as you slowly follow the route downward, you can see marine life from all over the world. The whole visit was very interesting.

    What I was looking forward to most was seeing the whale sharks in the huge tank. They leisurely swam around, and it was truly impressive when they passed right beside me. Besides the whale sharks, there were also rays, penguins, sea lions, and other marine animals. Seeing all kinds of marine life up close was very soothing.

    I really liked the overall atmosphere of Kaiyukan. The lighting is dim, and together with the blue glow from the tanks, walking through the aquarium feels like entering an underwater world. There are also plenty of good photo spots along the way, and before I knew it, I had spent quite a while exploring.

    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.

    The layout of Osaka Aquarium Kaiyukan is truly impressive. After entering, you first take an escalator straight to the top floor, then follow a comfortable spiral ramp downward, viewing the marine life in the same enormous tank from top to bottom and from different angles. The design is excellent. The stamp booklet offered inside is also a lifesaver—the stamp-collecting activity is beautifully designed and fun, and it completely keeps the kids' attention. They can look for stamps along the way, so the adults can explore at ease while the kids have a great time. It's a highly recommended attraction for the whole family to explore together!
