A green laser was fired at a Japan Ground Self-Defense Force helicopter during night training over Kem淵 Town in northern Hokkaido on Thursday [1], [2].
The incident highlights the persistent danger of laser strikes on aviation, which can blind pilots and cause catastrophic crashes during critical flight phases.
The helicopter, a UH-1J belonging to the 7th Division, was targeted twice by a green laser [2]. The beams lasted for a total of approximately five seconds [2]. The incident occurred at about 8 p.m. [2].
Four crew members were on board the aircraft at the time [1]. No injuries were reported among the personnel [1].
The 7th Division reported the incident to the police, citing aviation safety concerns [2]. The division described the event as "extremely regrettable," the 7th Division said [1].
Authorities have not yet identified the source or the motive behind the laser strikes [2]. The investigation into the origin of the beams continues as police look for individuals in the area who may have been operating high-powered laser devices.
“The beams lasted for a total of approximately five seconds.”
Laser strikes on aircraft are treated as serious security breaches because they can cause temporary flash blindness or permanent eye damage to pilots. When occurring during military night training, such incidents create additional operational risks and may be viewed as intentional interference with national defense activities.
