Wow this is awesome. I haven't gotten to see an iguana up close in so many years. They're really amazing creatures, apparently they're an invasive species in Japan. You learn something new every day I guess. I think I went to Sunshine City like last year or something but I haven't been to the Sunshine Aquarium before unfortunately. If they have iguanas then I'd love to go see them lol. I went to an aquarium a few years ago when I visited Kyoto but it's been a while since then. I really love checking out the jellyfish too, there's so many different types and the aquariums I went to in the US never seemed to have any which seemed kind of strange. Still hoping one day I'll get to see one of the dolphin shows that I always see. I seem to always barely miss the line and the wait time until the next one is always really long. Japan has some really cool aquariums though, so I'm looking forward to when I can visit them!
