Ryugu Sea Cave
下田市田牛Ryugu is a cave with a 50-meter diameter (roughly 164 feet) skylight. It is a strange place. If you look up from the bottom of the cave you will see a gaping hole in the ceiling. There is a walkway circling the top rim of the cave that you can walk around. If you look down into the cave from the top, you will see heart-shaped terrain. It is a popular heart-related spot which is visited by many people.
