If you dream about diving with huge schools of scalloped hammerhead sharks, this is one of the few places in the world where you can do that! The intense adrenaline you will experience when you suddenly see more than 100 hammerhead sharks is indescribable! Yonaguni is also home to the famous underwater ruins.
