The government may be making contingency plans to deal with a possible ballistic missile attack by North Korea, but it has confirmed Japan has one less high-flying national security threat to worry about--UFOs.

Prime Minister Shinzo Abe’s Cabinet on Feb. 27 approved an official response about the threat from unidentified flying objects that said "their existence has not been confirmed" and "we have not made any particular consideration of how to respond should one fly into Japan."

The response was made to questions raised by Seiji Osaka, a Lower House member of the opposition Constitutional Democratic Party of Japan.

Osaka pointed to a recent article in The New York Times about a secret study on UFOs conducted by the U.S. Defense Department between 2007 and 2012.

He wanted to know if a UFO attack would be considered an "armed attack situation" in which Japan was directly attacked militarily or a survival-threatening situation defined under national security laws as warranting the exercise of the right to collective self-defense.

This was not the first time the government has officially addressed the issue of UFOs.

In 2007, the Cabinet approved a similar response that said the existence of UFOs had not been confirmed.

However, at a news conference at that time, Chief Cabinet Secretary Nobutaka Machimura said, "The official response from the government is extremely stereotypical. I personally believe (UFOs) definitely exist."
