According to police and airport offices, a utility knife was found in the ANA lounge in the restricted area of Naha Airport in Okinawa Prefecture at around 5:45 pm on the 25th.
In response to this, security inspection procedures have been suspended at the airport, so there is a long line of people waiting for departure in front of the inspection site.
According to ANA, the departure of passenger planes from Naha Airport has been suspended since 6 pm due to this effect.
Also, according to Japan Airlines, the security inspection that had been suspended was resumed at 7:05 pm, but the departure flight was delayed by about an hour.
