Idenoyama Aquarium in the midst of Idenoyama Park is showing of many different freshwater fish endemic to Japan as well as spectacular crowd favorites like piranhas and adorable turtles. Even though it may not be the biggest aquarium, it is well worth a visit. More than 1500 fish await you! Impressive ancient pirarucu, arowanas with their huge scales and cute mickey mouse platies are fun to watch for children and adults alike.
The entrance fee is an affordable 200JPY (100JPY for kids up to 15 and 150JPY for groups of 20 people or more).
If you happen to be around during mid May to end of July, make sure you don’t miss out on the magical firefly dances in the park!
