Just 4km north of the Hirara district of Miyakojima city, you'll find this little, archetypally tropical Japan beach, which lies at the bottom of a large sand dune (hence the name 'Sand Mountain Beach'). If you've only got one beach day to spend, or are getting around via bus, park yourself here. Find showers and toilets here, too.
