Sheda11Kabutogani Museum is located right next to the dinosaur park, and is a great spot to visit if you have an hour or so to kill. You will receive a map and a stamp page to collect stamps as you make your way through exhibits. It features fossils of Horseshoe Crabs from years ago, and also some live ones to observe. The museum moves in a circular direction due to the building structure, and there is a ramp that leads to the 2nd floor where you will find a moving dinosaur, more fossils, and a balcony that lets you breath some fresh ocean air. This museum is popular amongst school children, but for adults it is very dated. There is a short film you can watch at the end of your walk through that talks about the history of the Horsheshoe crab, which unfortunately is all in Japanese. Still, it was fun guessing the answers to the pop quiz at the end of the movie by pushing the A, B, C buttons located next to my seat. The cost is about 500 yen ($5) for adults, less for children.
M32***23I went to the observatory, where you can visit the quarry (the visit fee is 1,000 yen), and rent a bicycle to walk halfway around the island. Everything is a good experience, but I think the biggest tourist asset is the slow flow of island time. The boat ride is very convenient and you can enjoy the extraordinary feeling of a short boat trip.
