Japan has rejected requests for entry by five North Koreans due to tightened immigration regulations imposed after Pyongyang's missile tests on July 5, the Justice Ministry said.

The group included Sin Kim Nyo, 75, and two others seeking the remains of relatives forcibly brought to Japan from the annexed Korean Peninsula before and during the war. The other two were an interpreter and a caregiver.

"A comprehensive judgment was made based on it," a ministry official said. The North Koreans have been notified of their rejections.
