I have always wanted to visit an aquarium in Japan. When I found out that at Sea Paradise visitors can touch marine animals for free, I just had to go there. Since Sea Paradise is an island surrounded by sea, walking along the bridge going to the island was a challenge. The wind was so strong it almost knocked me off my feet. I suggest not going there on a very windy or rainy day. There are plenty of restaurants in the area and some even offer an "All you can eat" buffet.
