By Space Coast Daily // September 20, 2016

Fishhooks found on a southern Japanese island date back some 23,000 years, making them among the world’s oldest fishing implements, researchers said Monday.
The hooks were discovered in Sakitari Cave on the southern end of Okinawa island several years ago, said Masaki Fujita, chief researcher for the study and a curator at Okinawa Prefectural Museum and Art Museum.
“And we have finally concluded that the geological layer in which the fishhooks were found was formed 23,000 years ago,” Fujita told AFP.
