Asahi and Sankei wrote that the man arrested earlier this week for shining a green laser at a U.S. military plane that was conducting a training flight near Yokota AB in February has confessed that he had been performing such illegal acts since three years ago. About 40 similar incidents have occurred in the vicinity of the U.S. installation in the past 15 months and the suspect is allegedly being held accountable for at least a dozen of them.
