Wearing a rubber ring, the 20-year-old Chinese national submerged herself in the water for 36 hours before being discovered off the coast of a peninsula south of Tokyo by a cargo ship.
According to the news agency, two crew members of a smaller adjacent vessel dived into the water to save the woman after receiving a warning.
The woman was later transported to a hospital by Coast Guard helicopters; she was conscious but dehydrated, the Kyodo news agency reported.
The woman, who has not been named, went swimming in Shizuoka Prefecture and reported missing, alerting police on Monday night.
We learned of the woman’s whereabouts at approximately 7:55 p.m. [10:55 GMT] on July 8, according to a local Japan Coast Guard official who spoke to news. The woman’s companion had reported her missing to a nearby convenience store.
He stated that there was “80km in a straight line” between the beach she was on and the spot where she was rescued off Chiba prefecture’s Boso peninsula. “But it is assumed she drifted for an even greater distance.”
The woman told rescuers that the rubber ring was the reason she had been swept out to sea and had not been able to get back to the shore.
