Kaiyukan is an aquarium that faithfully reproduces the natural environment of the Pacific Ocean and its surrounding waters. Each region of the Ring of Fire that surrounds the Pacific Ocean has been selected and reproduced in a large tank. Each tank in the aquarium is positioned to correspond to an actual geographical location in the Pacific Ocean. Approximately 30,000 creatures of 620 species are kept and exhibited in various tanks, including the "Pacific Ocean" tank in the center of the building where whale sharks swim leisurely, the "Japanese Forest" tank with a waterfall and lush vegetation, and the "Tasman Sea" tank where white-sided dolphins live. The "Jellyfish Galaxy" tank, which explores the charm of jellyfish, and the "Arctic Circle" tank, where ringed seals and other creatures live, are also popular.
△ [Aqua Gate] A world of blue spreads out before you, like a transparent undersea tunnel.

△ [Tasman Sea] In this tank, Pacific white-sided dolphins swim dynamically.

△ [Pacific Ocean] This tank is home to many creatures, including majestically swimming whale sharks, gracefully flapping manta rays, and schools of starlings.

Great but short, whale shark was simply amazing! Very educational to both adult and kids! Worth recommending!
เป็นสถานที่ท่องเที่ยวที่ตื่นตาตื่นใจมาก ถึงพระเอกหลักคือฉลามวาฬตัวใหญ่แต่สัตว์อื่นๆที่อยู่ที่นี่ก็น่ารักมาก มีนาก เพนกวิน โลมา ปลาต่างๆ มีโซนแมงกระพรุนสวยๆด้วย เหมาะกับการไปเที่ยวกับคู่รักและครอบครัวมาก
Osaka Aquarium Kaiyukan has a wide variety of marine life species, including marine fish from the Arctic and Antarctic Circles, the Pacific Ocean, Monterey Bay, the Aleutian Islands, the Ecuadorian rainforest and other waters. The giant tank here is one of the largest indoor water tanks in the world and is also the core area of Kaiyukan. There are many large marine creatures such as whale sharks, manta rays, hammerhead sharks, penguins, seals, sea lions, various jellyfish swimming in the water, and the crystal clear body of the big fin reef squid, etc., which make people admire the magic of nature's creatures. Super big visual enjoyment, but also increase knowledge and knowledge. [Fun] [Value for money]
This aquarium has received mixed reviews, but I like it very much. Those who say it is not very good may think that it is very small, there are no animal performances, and it is less interesting. The reason why I like it is that it is really very clean. There is no odor throughout the whole process. Looking through each glass display window, both the water quality and the area where amphibians are active are very clean. The museum is not big, but the fish on display are from small to large, step by step, which makes people feel orderly and rhythmic. The final "highlight" is the various fish in the huge "fish tank", with the protagonist being the whale shark, which is very dreamy with the music. The coffee shop after coming out has good ice cream and you can also watch the sunset of Osaka Port, which is perfect.
Osaka Aquarium KAIYUKAN is one of the must-visit tourist attractions in Osaka. This aquarium attracts the curiosity of many children, especially some deep-sea creatures in the Sea of Japan, which are more bizarre and varied in shape, and are more popular with children. There are also chubby seals 🦭, cute penguins 🐧, etc. The aquarium also sells commemorative coins 🪙, so friends with a hobby for collecting should not miss it.
A must-do itinerary when traveling to Osaka with kids! When I bought the ticket at the door, I found it very considerate that there are two ticket prices for children, 400 for those over 4 years old and 900 for primary and secondary school students. The prices are different. My son is exactly 5 years old, and they only ask about his age, not his height, so I still think it is very cheap. The transportation is convenient and the traffic flow in the museum is well planned. It is the largest indoor aquarium in the world. The best thing is that you don’t have to go to the Hokkaido Pavilion to see king penguins. I was very happy to see a group of penguins. It turns out that they sleep standing up. They are so cute! There is a sink at the exit (I think the Japanese are very considerate). Children can touch the stingray after washing their hands. My son had a lot of fun. There was a discount at the mall next to it, so my mother was very happy to buy something. I would like to go there again next time because I haven’t taken the boat to Osaka yet.
Osaka Aquarium Kaiyukan is located in Tempozan Harbor Village. Next to it is Osaka Port. The unique location makes people feel more immersive. The theme of Kaiyukan is based on the "Gaia Hypothesis" proposed by James Lovelock. It roughly means that the earth is a self-regulating living organism. But this does not mean that the world is alive, but it shows that there is a complex and coherent interaction between living organisms and the natural environment, including the atmosphere, oceans, polar ice caps, and the rocks under our feet. And these interactions work together to keep the earth in a moderately stable state so that life can continue to survive. Similarly, the earth with frequent volcanic activity also interacts with all living things. The Pacific Ring of Fire is roughly consistent with the areas where a large number of organisms live. Therefore, the lifeline design of Kaiyukan was carried out with RING OF FIRE and RING OF LIFE as the main lines. The tour of KAIYUKAN begins with the tunnel-type tank "Fish Crossing Watergate", starting with the sun-drenched "Japan Forest", and centered on the "Pacific Ocean" tank with a water storage capacity of 5,400 tons, where the world's largest fish "whale shark" swims. The route that circles the Pacific Ocean twice extends from the ground to the bottom of the sea. From the land where birds and animals live, diving into the ocean where schools of fish swim, and finally reaching the mysterious deep sea world. It is really super shocking to be able to observe the life and ecological environment of marine life from various angles! ! ! The last stop of KAIYUKAN is to see penguins, seals and other cute and smelly guys up close! You can also go into the water and feel the "love" from manta rays and small sharks. It's super slippery, isn't it? Finally, the Kaiyukan at night is very dreamy, all kinds of dreams, and the jellyfish pavilion with a starry sky is extremely romantic. It would be great if you could be stung by a jellyfish, so that you can stay here~ Of course, I'm just saying this, haha~
