At some point this beautiful beach was covered in so much marine debris that nobody swam here anymore. Then, one local decided to return the beach to its original state, and for the next couple of months he collected trash at Shirahama every morning before work. Other islanders were inspired by his efforts, joining in the morning beach clean-up. Eventually, the debris got cleared out and Shirahama became one of Ojika's most popular beaches. It has also spread awareness about the sea pollution problem among locals and travelers, earning its SDGs Beach title.
PLEASE DO NO SIT OR LIE DOWN ON THE WET SAND.
The wet sand is inhabited by an insect (ヒメスナホリムシ in Japanese) that bites. If you stand, sit, or lie down on the wet sand for more than a few seconds this insect will climb onto you and bite you (the pain is not extreme but unpleasant regardless).
Please note that there is no toilet at the beach.
There is a shower room but it is not managed by the town so it might be covered in sand, etc..
There is a running tap where you can wash your feet, etc..
