Churaumi Tropical Dream Center
Close to the Aquarium there is also a botanical gardens area nicly called the Tropical Dream Center. We also went to check that out as well. It was full of lots of cool tropical flowers, and lots of other kinds of plants and exhibitions too. When we went there was a special Orchid exhibition with over 2000 orchids.
On the way back we found a cheap and good unagi/eel place. Yay!
