Kagoshima City Aquarium (Io World)

The Io World Kagoshima City Aquarium, one of the largest aquariums in Kyushu, is easily recognized due to its unique architecture.
Located just by the Sakurajima Ferry Terminal, it is easy to get to from downtown Kagoshima City and from Sakurajima.
The displays focus on the marine life of the Kaogshima coast and Kinko Bay, which lies just before you.
You can also see dolphins swimming happily in the open-air Dolphin Waterway outside the aquarium.
*The Dolphin Waterway runs right next to the Kagoshima Aquarium

* Nighttime at the Aquarium events held during Golden Week (late April-early May), weekends during summer vacation, the Bon holiday (mid-August), and Christmas Eve
