Russian security services have arrested Yuki Imai, a correspondent for the Japanese newspaper Hokkaido Shimbun, in the Sakhalin region on suspicion of espionage. The Federal Security Service (FSB) announced the detention on Tuesday, accusing the 34-year-old journalist of gathering information about Russia's military capabilities and the recruitment of soldiers for the war in Ukraine.
According to an FSB statement, Imai "collected and stored information related to the country's defence capability, with the aim of passing it on, on the instructions of the national intelligence service, for use against the security of the Russian Federation." The agency released video footage showing masked officers entering a hotel room, handcuffing Imai, and conducting a search before escorting him to an aircraft.
Imai has been transferred to Moscow, where the Lefortovo District Court ordered his detention for at least two months. He will be held in the Lefortovo pre-trial detention centre. The Russian Foreign Ministry confirmed that a criminal case has been opened under Article 276 of the Criminal Code, which covers espionage. If convicted, Imai faces a prison sentence of 10 to 20 years. A trial date has been set for 12 December.
Who is Yuki Imai?
Imai holds accreditation from Russia's Foreign Ministry and has been travelling to the country since at least 2014. This summer, he participated in an expedition to former camps in Primorsky Krai where Japanese prisoners of war were held during the Soviet-Japanese War of 1945. In September, he was preparing a report on the unveiling of a monument in Khabarovsk commemorating the Soviet victory over militarist Japan. His most recent article, published in October, focused on the presence of North Koreans in the region.
Hokkaido Shimbun is a major Japanese outlet that covers events on Sakhalin and the Kuril Islands, as well as relations between Russia, Japan, and North Korea. This arrest marks the first detention of a foreign journalist since the release of Wall Street Journal reporter Evan Gershkovich in a prisoner swap in 2024. In 2019, Russian authorities detained a Japanese reporter from Kyodo News in Vladivostok on similar charges, but he was expelled within 72 hours.
Tokyo demands answers
The Japanese government has formally requested an explanation from Moscow. Chief Cabinet Secretary Minoru Kihara said Tokyo had been unable to contact Imai and only learned of his arrest through official announcements. Foreign Minister Toshimitsu Motegi stated that the Japanese embassy in Moscow and the consulate general in Yuzhno-Sakhalinsk have demanded immediate information and guarantees of humane treatment. Local media report that Japan plans to summon Russia's ambassador, Nikolai Nozdriev, to lodge a protest and demand Imai's release.
The arrest comes amid deteriorating relations between Russia and Japan, which have been locked in a decades-long dispute over the Kuril Islands. The two countries have never signed a peace treaty formally ending World War II. Japan joined Western sanctions against Russia in 2022 following the full-scale invasion of Ukraine. In August, President Vladimir Putin visited the Kuril Islands for the first time, prompting a strong protest from Tokyo.
This incident is part of a broader pattern of Russian actions against foreign journalists and perceived threats. As NATO warns about escalating hybrid attacks across Europe, the detention of a Japanese reporter underscores the Kremlin's willingness to use espionage charges as a tool against foreign media. The case also highlights the fragile security environment in the region, where Russia continues to strike Ukraine's energy grid despite international calls for a ceasefire.
For Japan, the arrest is a direct challenge to press freedom and diplomatic norms. The government's response will be closely watched, as it balances its condemnation of Russia's actions with the need to protect its citizens abroad. The trial, scheduled for December, will be a test of Russia's judicial independence and its willingness to engage in a fair process.
