History
Kagoshima Aquarium opened on May 30, 1997,[3][4] and exhibits marine life from the Kagoshima coast, which is washed by Kuroshio, and Kagoshima Bay. Brackish water and river life are also exhibited. Some of the aquarium's most popular attractions are the whale sharks and lamellibrachia satsuma. The Japanese name "Io" means fish in Kagoshima dialect.[5]
In total, it cost approximately 12.7 billion yen to build the aquarium.[4] The appearance of the aquarium is based on a stingray.[4] Kagoshima Aquarium was the first aquarium in Japan to successfully breed Chinese sturgeons in captivity. [6] In October 2011, the number of visitors reached ten million.[7] At the end of the route is the "Sea of Silence", conceived by the aquarium's first director. Fish and other marine life are not exhibited inside this tank and is filled only with water. It has been said that this is to make people think about the marine environment.[8]

Whale sharks
The Kagoshima Aquarium has a large tank with a water volume of 1,500,000 litres (396,000 US gal), but it is not large enough to house whale sharks that easily exceed 10 m (33 ft) when fully grown.[11] Therefore, whale sharks kept at Kagoshima Aquarium are exhibited using the "Kagoshima method", in which training is conducted to return them to the wild before the body length reaches 5.8 m (19 ft). A transmitter is attached to the whale shark that returns to the wild, and the aquarium has been successful in grasping the migration route of the whale shark.[12]。
The whale sharks raised in the Kuroshio Tank have been named "Yuyu" for generations, and are among the aquarium's most popular attractions.

Two whale sharks were planned to be exhibited as a highlight from the aquarium's opening in 1997, but they died in March and May of the same year. As a result, the aquarium opened its doors without a whale shark.[4]
Tropical bottlenose whale skeleton

A whole-body skeletal specimen of a tropical bottlenose whale is displayed in the observation hall on the fifth floor. Tropical bottlenose whales are extremely rare in the wild, and it is rare to observe whole-body skeleton specimens.
This skeleton is a specimen of an individual that washed ashore in Satsumasendai City on July 26, 2002.[15][16]
Jellyfish corridor
The jellyfish corridor opened in March 2017, and exhibits the world's first deep-sea inhabited sanderia malayensis.[17]
Japanese wedgefish

In 2020, research by groups such as Kuroshio Biological Research Institute revealed that the aquarium's giant guitarfish, housed at the aquarium since its opening, was, in fact, a new species, the Japanese wedgefish.[18][19]
