Russia and Japan's longstanding territorial row
Successive Japanese governments have consistently taken the position that the islands were illegally annexed, with the dispute so impacting bilateral ties that the two nations have yet to sign a formal peace treaty.
The collapse of the Soviet Union in 1991 and the subsequent economic hardships gave Japan renewed hope that Moscow could be convinced to return the islands in return for economic assistance or even joint development of the region.
uncertain
Moscow → take → region
Former Japanese Prime Minister Shinzo Abe was arguably the most proactive Japanese leader on the issue, meeting with Putin on a number of occasions in an effort to convince the Russian leader to come around to Japan's way of thinking.
However, all of these diplomatic efforts came to naught, with Russia amending its constitution in 2020 to ban the ceding of any part of Russian territory to a foreign power.
asserted
Russia → meet → power
Moscow's relations with Japan further deteriorated after Russia's full-scale invasion of Ukraine in February 2022.

Toshimitsu Shigemura, a professor of politics at Tokyo's Waseda University, told DW that these latest developments are just another nail in the coffin for Japan's ambition concerning the islands.
asserted
developments → tell → islands
"Tokyo has already summoned the Russian ambassador and made a formal diplomatic protest, but sanctions are already in place over the Ukraine war and I think it will be difficult for Japan to add more," Shigemura said.
asserted
Shigemura → summon → more
"Japan is importing Russian energy and, because of the situation with Iran, that has become even more important, which leaves Tokyo in a relatively weak position," he added.
asserted
he → import → position
Putin tests Japan
Shigemura believes that Putin — potentially in consort with China and North Korea — is attempting to weaken Japanese Prime Minister Takaichi because of the firm line she has taken on security issues in the region.
asserted
she → test → region
He added that Putin is aware that Takaichi's domestic poll numbers are softening, and likely assesses the Japanese leader will not respond more forcefully than a protest.
asserted
leader → add → protest
Shigemura added that Russia's revised constitution and deepening nationalist sentiment encouraged by state propaganda effectively makes it "impossible" for the islands to be returned to Japanese control.
asserted
islands → add → control
"Putin may be weak now, but he is cooperating with China and North Korea to challenge Takaichi, who has few options," he said.
uncertain
he → cooperate → options
"And even after Putin has gone, there will be no interest in a new Russian government to return the islands."
asserted
Putin → go → islands
Brown agreed, saying that while a few "excitable commentators" in Japan will see Putin's eventual departure from the Kremlin as an opportunity, whomever ends up controlling Russia will be unlikely to align with Japan's territorial interests.
asserted
ends → agree → interests
"It did not happen with the collapse of the Soviet Union and all through Russia's subsequent economic difficulties so I don't see any new Russian leader who comes in as countenancing returning the islands," he said.
asserted
he → happen → islands
