Two people were killed Wednesday after a cadet allegedly opened fire on members of his own unit at a military training center in central Japan, the country's Ground Self-Defense Force (SDF) has told CNN.

The shooting took place during a live-fire training exercise and several other people were wounded, the SDF confirmed to CNN. The cadet was arrested and the motive has yet to be established, authorities said.

Japan's Chief Cabinet Secretary Hirokazu Matsuno said the incident happened around 9 a.m. at a shooting range in Hino City in the central Japanese prefecture of Gifu.

"We have received a report that the SDF personnel who fired the rifle has already been taken into custody. We will refrain from giving further details as the investigation is ongoing," Matsuno said.

Matsuno said at least three people were wounded.

Japanese public broadcaster NHK reported that the suspect was a teenage member of the SDF who allegedly fired an automatic rifle.

CNN has reached out to the Gifu fire station and police.

Gun violence is extremely rare in Japan, a country of 125 million people. It has one of the lowest rates of gun crimes in the world due to its extremely strict gun control laws.

But a string of high profile violent crimes have recently been reported in the country.

Last month, four people -- including two police officers -- died in a shooting and stabbing incident in Nakano City in central Japan.

In 2022, nine incidents involving firearms took place in Japan -- including the assassination of former Prime Minister Shinzo Abe who was shot dead with a homemade gun during a campaign speech -- according to the National Police Agency.

Of the nine incidents, six are believed to have been committed by gangs and other groups. In total, four people were killed and two injured in the nine incidents.
