It did not provide details of the alleged crime. But it said North Korean officials had decided to “leniently condone him and expel him” from North Korea “on the principle of humanitarianism.”

Japan’s Kyodo News agency reported earlier that a Japanese videographer on a group tour appeared to have been detained in North Korea after shooting footage of a military facility while visiting Nampo, a port city south of Pyongyang, the North Korean capital.

Japan and North Korea have been in talks on and off over Tokyo’s demand that the North return Japanese citizens said to have been kidnapped by the North during the 1970s and 1980s. The abductees issue remains the thorniest issue dividing the neighboring countries.

North Korea has a history of holding foreigners accused of committing vague “crimes against the state,” and releasing them only after high-ranking officials or dignitaries visit Pyongyang, North Korea's capital, to seek their freedom.

North Korea released three Korean-Americans, including one sentenced to 10 years of hard labor for an espionage conviction, when Secretary of State Mike Pompeo visited Pyongyang in May. Early this month, it released a South Korean citizen who had been detained in the North since July.

The releases came amid a political thaw on the Korean Peninsula that began early this year when the North’s leader, Kim Jong Un, began negotiations with South Korea and the United States on improving ties and denuclearizing the peninsula.
