The shutdown forced delays in 70 flights at one of the country's busiest airports.

The man was spotted by infrared sensor at around 4 a.m., and all incoming and outgoing flights were grounded while authorities tried to track down the person.

The man turned out to be a 22-year-old part-time employee of a company that cleans airplanes, and is under contract with All Nippon Airways. The man said he was not familiar with airport security and that he wanted to go for a jog by the sea.
