Japan summons Russian ambassador seeking information and contact
Infobae ↗FSB reports court ordered two months in custody
Mint ↗Russian foreign ministry urges Tokyo to change approach
RT en Español - Noticias ↗FSB says detained reporter was transferred to Moscow
Al Jazeera ↗Russian state television shows man being handcuffed

Infobae ↗How it started
Russia's Federal Security Service, known as the FSB, announced on October 13 that it had detained a Japanese journalist on Sakhalin Island in Russia's far east, according to Infobae. The reporter works for the Hokkaido Shimbun newspaper.
Al Jazeera identified him as Imai Yuki. NYT World News reported that he had been covering military recruitment before his detention. That reporting subject is distinct from the espionage allegations Russian authorities have made against him.
How it unfolded
On October 13, reports described Russia's accusation that the journalist had gathered information about its defence capabilities. Sky News reported the allegation, citing news agencies.
Russian state television showed a man lying on a floor being handcuffed by three masked men in black uniforms, according to World News CNA. The footage accompanied coverage of the detention.
The FSB said the reporter was transferred from Sakhalin to Moscow after his arrest, Al Jazeera reported on October 13.
Moscow also turned the detention into a diplomatic warning. RT en Español - Noticias reported on October 13 that Russia's foreign ministry urged Tokyo to abandon what it described as hostile measures towards Russia.
By October 14, Mint reported that a court had ordered the journalist held in custody for two months, citing an FSB statement. That day, Japan summoned Russia's ambassador in Tokyo, Nikolai Nozdrev, to request information and an opportunity to contact the reporter, according to Infobae.
Where it stands
The journalist remains subject to the two-month custody order reported by Mint. Japan's latest reported action is its request for information and contact through the Russian ambassador, according to Infobae.
The accusation concerns information on Russia's military readiness, mobilised troops and volunteers for the war in Ukraine, according to Russian security services cited by Euronews. These are the authorities' allegations. The supplied coverage does not establish that the journalist committed espionage or provide a response from him.
What to watch
The immediate issue is whether Japan receives the information and opportunity for contact it requested. Infobae reported the request, but the supplied coverage does not say whether Russia has granted it.
Further details of the legal case also remain pending in this coverage. Mint reported the custody order, but the supplied reports do not set out a trial timetable or the evidence supporting the espionage allegation.
