It's no coincidence that the word "muse" is in "museum!" Ayashii Museum aims to inspire and educate visitors, so consider adding it to your itinerary.
Head on over to Futo, pay the admission fee and find out why Ayashii Museum is a crowd favorite. Consider hanging around for a while longer, because there are some other great attractions not far from this museum. Atagawa Tropical and Alligator Garden, Izu Oceanic Park and Izu Glass and Glasswork Museum are a few suggestions.
