SEOUL, South Korea — North Korea has decided to expel a Japanese man accused of committing a crime while visiting the isolated country on a tourist visa, the country’s state media reported.

The man, Tomoyuki Sugimoto, has been held in North Korea for an investigation of “his crime against the law,” the Korean Central News Agency said in a brief dispatch late Sunday.

It did not provide details of the alleged crime. But it said the North Korean authorities 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.
