Government spokesman Minoru Kihara said the Japanese embassy in Iran had verified the release and that Japan’s ambassador had met the individual in person after their detention ended.

“The Japanese embassy in Iran has confirmed that a Japanese national who was detained by Iranian authorities on January 20 was released on April 6 local time,” Kihara told reporters, adding the individual’s health condition had been confirmed as stable.

Japan’s NHK was reported by Kyodo News to have identified the detainee as its Tehran bureau chief, although the broadcaster did not immediately confirm the report when contacted.Media reports earlier said the individual had been transferred to a prison known for holding political detainees following their arrest in January.

Japanese officials had previously acknowledged the detention but declined to provide further details at the time.

The release marks the second such case in recent weeks, after Tokyo announced last month that another Japanese national had been freed by Iranian authorities.
