Why Osaka Aquarium Kaiyukan is special ?

Osaka Aquarium (Kaiyukan) is one of the largest aquariums in the world. Osaka Aquarium features the display of two whale sharks. Osaka Aquarium obtains its Japanese name from the Japanese word Kaiyukan literally means 'Playing in the Sea Pavilion'. In this aquarium, visitors can enjoy creatures as if they are playing together in the sea. Osaka Aquarium consists of 15 water tanks centered on a single huge tank holding 11,000 tons of water (the world's top-class by volume). Osaka Aquarium is home to 580 species and 30,000 marine animals from the Pacific Rim everything from strangely delightful jellyfish, to playfully chortling sea otters, to dolphins, penguins. Among them, giant whale shark, the largest fish on earth, named 'Kai-kun' is the most popular creature of all.


What to explore at Osaka Aquarium Kaiyukan?

The journey through Osaka Aquarium begins with a series of elevator rides up to the top of the building. As a gauge, the Kaiyukan is about 8 floors high by normal building standards. The top entrance floor houses fuzzy animals like the capybara, sea lions, otters and penguins.

But below the entire central space is taken up mostly by the giant tank that accommodates the aquarium’s largest inhabitants. You’ll find the chief attraction, a female whale shark called Yu-chan.

The path through the aquarium spirals downward around the central tanks. Apart from the obvious supporting columns, all of the water bodies here are almost completely see through. While the central area houses the larger animals, the circumference is home to the other tanks that support the other amazing creatures like the octopuses, sea turtles, plethora of different fishes and the two breeds of dolphins here.

Each specimen has been lovingly named and a breakdown of the individual creature’s personality is also provided. Local children can watch the aquarium’s inhabitants grow up alongside them, while it’s convenient enough for enthusiasts could come to meet the creatures from time to time.

There are simply too many specimens featured here to list down individually but notable is the rarely seen ocean sunfish.

    Ticket and Pricing


One of the best aquariums I've been to, but honestly, I haven't been to very many to make a comparison. At ¥2300 for admissions, it is a reasonable price for how much you see and how much time you can spend at the aquarium. The biggest attraction is obviously the whale shark, but I was most impressed by the layout of the aquarium itself.the large tank with the whale shark and other fishes are centered in the middle and the path in which you walk spirals downward, so you get a glimpse of this magnificent whale shark at every angle. On the outskirts of this tank are the other exhibits like jellyfish, tropics, reptiles, seals, etc. it's a very easy walk-through and I think I saw everything in a span of 2-3 hours. The gift shop is located right at entrance/exit. Plenty of plushies, pillows, socks and other gifts to buy. I bought a few keychains of the whale shark because they are absolutely adorable and you can't fine them anywhere else. Definitely worth checking out. It's a total date spot with many couples and families. The surrounding city is really quaint and quiet, but we didn't stick around long enough to venture around. Hopefully the weather is much more favorable than rainy and windy for you!

If you're visiting Osaka do not miss this aquarium! It was by far the best aquarium I've visited to date. The set up was easy to navigate, it was interactive, the animals in the tank (referring to dolphins and sea lions, etc) seem really healthy & more importantly happy! This aquarium is on top of keeping the tanks clean. They have divers every day to scrub the tanks! I had saw a documentary on Japan's aquariums, and I must say I was impressed when I saw it in person too! The diver holds a brush in one hand and a plunger like suction to keep him in place longer for scrubbing. I went on a weekday but during summer break so it was crowded with tourists & families, I didn't see anything wrong with that! It's a public aquarium, people go there to learn & see, I don't understand the complaints about it being crowded like you expect VIP treatment or something. They have 2-3 feeding times per day, please try to catch as many as you can because these feeding times are what makes the experience that much more amazing. I'm an adult and have been to my fair share of aquariums here in the states, never seen anything like this in the states. From what I have read on reviews of the aquarium in Georgia, tickets cost more than Osaka, you have to pay extra to see things like feedings, etc. At the Kaiyukuan, you can also experience the feel of a sting ray, eagle ray, etc. My partner and I throughly enjoyed our visit here, make sure to allow 2-4 hours there.

Large aquarium, with some amazing creatures. 2000 yen. Went on a Sunday and it was insanely crowded. Cool water tube at the entrance. You can also get a Japanese guide downloaded onto your DS.
