Four people were confirmed dead Monday after their bodies were discovered in a submerged car off a port in Kagoshima Prefecture, police said.
Two of the victims, a man and a woman, were adults while the other two were believed to be minors, authorities said. The police are working to confirm their identities, they said.
The car was found by a fisherman in waters roughly 5 meters deep at around 5:35 a.m. near a port in the city of Akune, on Kagoshima's southwestern coast, according to the local fisheries cooperative.
A number of fishing-related businesses and restaurants operate near the site.
