The bodies of the remaining two crew members of a military plane that crashed in southern Japan were located Friday, the government said.
The other four bodies and part of the wreckage were found around 500 metres east of Mt Takakuma on the island of Kyushu the previous day, Kyodo News reported.
The search team was preparing to transport all the bodies to the Kanoya air base, where the jet took off Wednesday, Kyodo said.
"It is extremely regrettable and sad that competent crew members with a bright future ahead became involved in such an accident," said Defence Minister Gen Nakatani told reporters Friday.
The military has given no indication as to why the crash might have occurred.
Nakatani said the ministry will investigate the cause of the accident and do its utmost to prevent a recurrence.
The 15-metre twin-engine jet, which had been inspecting air navigation facilities, disappeared from radar at around 2:35 pm Wednesday (0535 GMT) about 10 kilometres north of the Kanoya base, Defence Ministry officials said.
There was thick cloud around the base near the time of the crash.
In February 2015, a military helicopter crashed, after leaving the same base, on a mountain in neighbouring Miyazaki prefecture, killing all three crew members.
