The bodies of a father and his 7-year-old son were found Saturday at a beach in Fukuoka Prefecture after they were swept out to sea with another boy and their would-be rescuer a day earlier, police said.
The bodies of Katsuhiro Ono, 36, and his son, Takeru, were found after the bodies of Ryo Morio, 5, and Kazuya Terada, 49, were recovered on Friday.
Ono was planning to marry Morio's mother and the four had come to the beach for the Bon holidays.
Swimming was prohibited in the area because of strong currents.
