An 18-year-old Japanese soldier was arrested on Wednesday after two people were killed and one injured in a shooting at a military facility in central Japan, the country's defence ministry said.
The Self-Defence Force (SDF) member is accused of shooting three people with an automatic weapon at a military shooting range in Gifu City about 9:00 am.
All three were taken to a hospital, but two died of their injuries.
Ground SDF Chief of Staff General Yasunori Morishita told reporters that the man accused of the shooting joined the service in April and that the victims were instructors. Police will conduct an inquiry, he said.
"We will investigate the cause of the incident to ensure that it doesn't happen again," Morishita said at a media briefing.
The victims included a man in his 50s and two in their 20s, and there were no reports of civilian casualties, public broadcaster NHK reported.
Shootings are extremely rare in Japan, where gun ownership is tightly regulated and anyone seeking to own a gun must go through a rigorous vetting process.
Former Prime Minister Shinzo Abe was shot and killed with a homemade gun in July. The suspect previously worked in the Maritime SDF.
