Moscow Jails Japanese Reporter on Spy Charges, Sending Russia–Japan Relations to a New Low

.

A reporter taken into custody on the eve of his departure

Russian authorities announced on Tuesday that they had detained a Japanese journalist in the Sakhalin region, in Russia's far east. The Federal Security Service (FSB), Russia's main domestic intelligence agency, says he was arrested one day before he planned to leave the country. It did not give the exact date.

The Foreign Ministry named him as Yuki Imai, who worked for the Hokkaido Shimbun, a regional daily from Japan's northern island of Hokkaido. The FSB claims he gathered and stored information about Russia's defence capabilities for Japanese intelligence. Russian state television aired footage showing masked officers handcuffing a man on the ground, then escorting him onto a plane and into a courtroom cage in Moscow.

The court ordered him held in custody until December 12, according to Russian news agency reports. Under Russia's espionage law, a conviction can bring up to 20 years in prison.

The Hokkaido Shimbun has not confirmed the details. The paper said it was still checking the facts and that the reporter's safety was its top priority.

Tokyo protests and demands access

Japan's government reacted quickly. Chief Cabinet Secretary Minoru Kihara said Tokyo had asked Russia for information and called for fair and humanitarian treatment. Foreign Minister Toshimitsu Motegi made a similar appeal.

Later, a senior Foreign Ministry official summoned Russian Ambassador Nikolay Nozdrev to lodge a formal protest. Tokyo objected both to the detention and to Russia's decision to publish its own version of events without first explaining anything to Japan. Japanese diplomats also asked for quick access to the detained journalist.

Asked whether Japan's gas purchases from Russia limit its options, Kihara acknowledged "many issues" between the two countries. He said Russia remains a neighbour and that talks are still needed.

Who is Yuki Imai?

According to the Russian outlet Meduza, which is now based outside Russia, Imai has travelled to Russia since 2014. His work covered everyday life on Sakhalin and Russia's growing ties with North Korea. His latest article, published on October 5, dealt with North Korean workers in the regional capital, Yuzhno-Sakhalinsk.

Moscow, however, describes him as an intelligence collector. Foreign Ministry spokeswoman Maria Zakharova accused Japan of using accredited correspondents to gather information that could harm Russian security. She also criticised what she called Japan's "remilitarisation". So far, the public account rests almost entirely on statements by Russian officials. It cannot be independently verified.

A pattern Western journalists know well

Foreign reporters have been a recurring target in Russia's espionage cases. The best-known example is Wall Street Journal correspondent Evan Gershkovich, arrested in 2023. He was convicted of espionage and sentenced to 16 years, and was freed in a prisoner exchange between Russia and Western countries in August 2024. He has said his arrest was a carefully staged operation by the FSB.

Japan has seen this before, too. In 2019, a Kyodo News correspondent was detained in Vladivostok and expelled. In 2022, a Japanese consul in the same city was detained and ordered to leave. Moscow accused both of spying, and Japan rejected the accusations.

Critics argue that such cases serve a political purpose. Detained foreigners can become bargaining chips, and the threat of arrest discourages independent reporting from inside Russia.

Why relations are at a low point

Russia and Japan have never signed a peace treaty ending World War II. The reason is a dispute over four islands at the southern end of the Kuril chain, which Russia controls and Japan calls its Northern Territories. The Soviet Union seized the islands in 1945, and about 17,000 Japanese residents were expelled.

Relations worsened further after Japan joined Western sanctions over Russia's invasion of Ukraine. Moscow now officially lists Japan as an "unfriendly" country. Still, trade has not stopped completely: Japan continues to buy Russian liquefied natural gas (LNG, natural gas cooled into a liquid for shipping).

In August, Vladimir Putin made his first visit to Iturup, one of the disputed islands. Japanese Prime Minister Sanae Takaichi called the trip "absolutely unacceptable." Last week, her cabinet approved additional sanctions against Moscow. On the day of the arrest announcement, a delegation from a Chinese province also visited the same island. Reuters described this as a possible sign of closer coordination between Moscow and Beijing against Tokyo.

What to watch next

The next steps are clear but uncertain. Japan wants consular access to Imai and clear information about the charges. Russia, for its part, has signalled that it expects the dispute to deepen.

Whether the case ends in a long trial or in a diplomatic deal, as in the Gershkovich case, is unknown. For now, a Japanese reporter sits in a Moscow detention centre, and press freedom in Russia is under renewed pressure.
