Japan’s Foreign Ministry summoned Russian Ambassador Nikolai Nozdrev over the detention of Yuki Imai, a 34-year-old correspondent for the Hokkaido Shimbun. Officials protested that Russia publicized accusations against him without providing an explanation to Japan or arranging consular access.

Radio Liberty reported the developments on Friday, October 16. Footage distributed by Russian state media showed security officers restraining Imai in Yuzhno-Sakhalinsk while an investigator told him he was suspected of spying for Japanese intelligence. He was later transferred to Moscow, where a Lefortovo court authorized his detention for at least two months.

The FSB alleged that Imai had collected information on mobilized residents and volunteers from the Kuril Islands who joined Russia’s war against Ukraine. Espionage charges carry a possible prison term of up to 20 years. Imai had returned to Russia during the summer, and his most recent report, published October 5, focused on North Korean citizens living on Sakhalin.

Experts interviewed by Current Time suggested the arrest might give Moscow leverage in dealings with Tokyo. They pointed to Russian-linked cybercrime suspects as possible exchange targets, including Vladimir K., who was detained in Osaka and extradited to Germany on October 2 over alleged ties to the Qilin ransomware group. Another possibility raised by analysts was pressure on Japan to ease sanctions, though the proposed outcomes were presented only as speculation.
