It is called "Phantom Island (official name: Hamashima)" because it disappears when the tide rises and a sandy beach appears when the tide recedes. It is characterized by its crescent moon shape when viewed from above.
The area around "Phantom Island," which has been used for TV filming and is shallow, is also popular with children.
