Sendai Airport shut down for about 90 minutes Wednesday while the Ground Self-Defense Force extracted the fuse and detonator from an unexploded bomb found recently near its runways.
Both domestic and international flight services restarted at around 10:30 a.m., except for flights canceled in advance, after airport officials decided it was safe.
GSDF personnel removed the fuse and detonator after the airport's two runways were closed and areas within 300 meters of the bomb were sealed off a little past 9 a.m.
The dud will be stored at a GSDF base in Yamagata Prefecture until its disposal is commissioned to a private contractor.
The bomb was unearthed Oct. 29 during reconstruction work.
