Russia arrests Japanese Hokkaido Shimbun journalist on spying charges in Sakhalin
Russia's Federal Security Service says it arrested a Japanese correspondent for the Hokkaido Shimbun in the Sakhalin region on suspicion of spying for Japanese intelligence. He was flown to Moscow and ordered held in pretrial detention.
Arrest in Sakhalin
Russia's Federal Security Service (FSB) said on Tuesday, 13 October 2026, that it had arrested a Japanese man who worked as a correspondent for the Hokkaido Shimbun newspaper in the Sakhalin region of the Russian Far East. The agency said he was accredited to the Russian Foreign Ministry and worked from the paper's Yuzhno-Sakhalinsk office. According to the FSB, he was suspected of gathering and storing information on Russia's defense capability in order to pass it to a Japanese intelligence service, for use against the security of the Russian Federation. The FSB said he was detained on the eve of his planned departure from Russia. The statement was relayed by the Interfax and TASS news agencies.
Custody and charges
After the arrest he was flown to Moscow and placed in custody. Investigators of the FSB opened a criminal case under article 276 of the Russian Criminal Code, the espionage provision. A Lefortovo district court ordered that he be held in pretrial detention, a measure that is not a sentence. The FSB did not disclose his identity and did not name him in its statement. Further investigative steps were reported to follow, according to the Russian agencies that carried the announcement.
Dispute over the Kuril Islands
The case comes as relations between Moscow and Tokyo have worsened since Vladimir Putin visited the Kuril Islands for the first time in August. Japan described that visit as unacceptable and claims part of the archipelago. Russia calls the islands the Southern Kurils and Japan calls them the Northern Territories. They are Iturup (Etorofu), Kunashir (Kunashiri), Shikotan and the Habomai group, and administratively they belong to the Sakhalin region. Japan says they still fall under Hokkaido prefecture and are illegally occupied by Russia. Tokyo has delayed signing a peace treaty for decades while seeking sovereignty over the islands, citing a bilateral treaty signed on 7 February 1855, whereas the Kremlin relies on treaties concluded at the end of the Second World War.
Wider security context
Japan has hardened its stance toward Russia since Moscow launched its large-scale offensive in Ukraine in 2022. Russia and China have recently moved closer, and their navies and air forces conduct joint exercises in areas near Japan. Those exercises lead Japanese aircraft to scramble hundreds of times a year. The arrest was announced on the same day that Russian authorities described the case as an intelligence operation linked to a Japanese service. So far the account of the case rests on the FSB statement as relayed by the agencies.
