Russian authorities have detained a Japanese journalist on suspicion of espionage, alleging he collected intelligence on Moscow’s military capabilities for Tokyo.
The reporter, identified as Yuki Imai of the Hokkaido Shimbun newspaper, was arrested in the far eastern Sakhalin region one day before his scheduled departure from Russia. He was transported to Moscow, where a court ordered him held in pre-trial detention, according to Russian state media.
Japanese officials say they are still seeking details regarding the arrest and have not yet been able to establish contact with Imai.
The detention occurs against a backdrop of deteriorating relations between the two nations following Russian President Vladimir Putin’s visit to the disputed Kuril Islands in August. The archipelago, administered by Russia but claimed by Japan as the Northern Territories, has been a decades-long obstacle to a formal World War II peace treaty.
Russia’s state news agency TASS reported that authorities accuse Imai of acting on instructions from Japan’s intelligence services to gather information about personnel involved in what Moscow terms its “special military operation” on the islands.
Interfax news agency stated Imai will remain in custody until December 12 ahead of his trial. Espionage convictions in Russia carry a maximum sentence of 20 years imprisonment.
“Tokyo’s attempts to use its correspondents in Russia, who hold foreign journalist status, to gather information aimed at undermining our country’s security are regrettable,” Russian Foreign Ministry spokeswoman Maria Zakharova said in a statement. She suggested the incident was not isolated but did not identify other journalists or outlets allegedly involved.
Japan’s Chief Cabinet Secretary Minoru Kihara told reporters that Tokyo was unaware of the arrest until the public announcement and had not yet made contact with the detained journalist.
Imai’s previous reporting has focused on Russia-North Korea relations and life in Sakhalin. Hokkaido Shimbun confirmed the arrest in a report that withheld the reporter’s name, stating that ensuring his safety remains the organization’s top priority.
Bilateral ties have remained strained since Japan imposed sanctions on Russia over its 2022 invasion of Ukraine. Tensions escalated further last week when Moscow requested the extradition of International Criminal Court President Tomoko Akane, a Japanese national placed on Russia’s wanted list in 2023 after the ICC issued an arrest warrant for Putin over alleged war crimes in Ukraine.
The case echoes previous detentions of foreign journalists in Russia. In 2023, Wall Street Journal reporter Evan Gershkovich was arrested on espionage charges and sentenced to 16 years before being released in a 2024 prisoner exchange. In 2019, a Kyodo News journalist was briefly detained in Vladivostok on suspicion of seeking military secrets and ordered to leave the country within 72 hours.
