TOKYO (AP) — Japan's guard says 10 of the 26 people aboard a tour boat that sank in the frigid waters of a northern national park have been confirmed dead.
The search for the others is still ongoing a day after the boat sent a distress call saying it was sinking.
The coast guard said Sunday that the bodies of the 10 victims included seven men and three women.
There were two crew and 24 passengers, including two children, on the tour boat when it ran into troubles on Saturday afternoon near the tip of Shiretoko Peninsula.
The location is known as a difficult place to maneuver boats because of its rocky coastline.
The Transport Ministry has launched an investigation into the boat’s operator, which had two accidents last year.
THIS IS A BREAKING NEWS UPDATE. AP's earlier story follows below.
The Japanese Coast Guard said Sunday that rescue helicopters found nine of the 26 people from a tour boat missing in the frigid waters of northern Japan since the day before, but their conditions are unknown.
The Transport Ministry, meanwhile, launched an investigation into the boat's operator over its safety standards and its decision to conduct the tour despite rough weather on Saturday.
“We will thoroughly investigate what caused this situation and what kind of safety oversight was involved to allow the tour in order to prevent another accident," Transport Minister Tetsuo Saito, who visited the area Sunday, told reporters.
The ministry will also investigate if or how Saturday's accident was related to two previous accidents involving the same boat last year, Saito said. The operator had been instructed to take steps to improve its safety following the incidents.
The coast guard confirmed that the same boat went aground in the area last June, though nobody was injured in that accident. In May, the boat collided with an object at sea, causing minor injuries to three passengers.
Rescuers intensified their search earlier Sunday and found four people near the tip of Shiretoko Peninsula and five more people in the same area a few hours later, but the coast guard said it could not confirm whether they were rescued alive. NHK public television said they were unconscious.
The coast guard said all nine people were found in the area near the tip of the peninsula north of where the boat sent a distress call on Saturday. The location is known as a difficult place to maneuver boats because of its rocky coastline.
Footage on NHK showed one of the rescued people arriving on a helicopter and being transferred to an ambulance on a stretcher, while rescuers held up blue plastic shields for privacy.
An orange-colored, square-shaped lifesaving float with the boat's name on it was also seen on the rocky coast.
The boat carrying 24 passengers, including two children, and two crew members went missing after sending a distress call, saying it took on water and was beginning to sink.
The first report of Sunday's rescue came after nearly 19 hours of intense search involving six patrol boats, several aircraft and divers. The coast guard said the search continued through the night and has since expanded, with local fishing and tour boats joining the efforts, while the Self Defense Force dispatched a destroyer and three planes.
The 19-ton Kazu 1 made an emergency call early Saturday afternoon, saying the ship’s bow had flooded and that it was beginning to sink and tilt, while traveling off the western coast of Shiretoko Peninsula on the northern island of Hokkaido, the coast guard said.
The tour boat has since lost contact, according to the coast guard. Seventeen people are still missing. The coast guard said the operator told them that everyone on the boat was wearing a life vest.
Average April sea temperatures in Shiretoko National Park are just above freezing.
An official for the vessel’s operator, Shiretoko Pleasure Cruise, said he could not comment because he had to respond to calls from worried families of the passengers.
Prime Minister Fumio Kishida, who was attending a two-day summit in Kumamoto in southern Japan, canceled his program for the second day and returned to Tokyo. He told reporters in the early hours of Sunday that he instructed officials “to do everything they can for the rescue.”
The cause of the accident is still under investigation, but experts suspect there may be a safety negligence, and the boat ran aground and was damaged in rough seas in an area known for strong currents and a rocky coastline.
High waves and strong winds were observed in the area around noon, according to a local fisheries cooperative. Japanese media reports said fishing boats had returned to port before noon because of the bad weather.
NHK said there was a warning for high waves of up to 3 meters (9 feet).
A tour boat crew belonging to another operator told NHK that he warned of rough seas when he spotted the Kazu 1 crew and told them not to go. He said the same boat went aground last year and suffered a crack on its bow.
Yoshihiko Yamada, a Tokai University marine science professor, said the boat was likely to have run aground after it was tossed around in high waves and damaged, flooded and probably sank. A tour boat of that size usually does not carry a life boat, and passengers possibly could not escape a rapidly sinking vessel with its windows likely closed to shield them from strong winds.
In an interview with TBS television, Yamada said there was also a slight possibility the boat could have been hit by a whale.
The cold temperature and strong wind could cause hypothermia and put the passengers in severe conditions for survival, according to Jun Abe, vice chairman of the Society of Water Rescue and Survival Research. “It’s a very severe condition especially when they are wet,” Abe told TBS.
According to the operator’s website, the tour takes around three hours and offers scenic views of the western coast of the peninsula and includes potential sightings of animals such as whales, dolphins and brown bears. The national park is listed as a UNESCO World Heritage site and is famous as the southernmost region to see drifting sea ice.
