What happened

Japan said Friday (August 21, 2026) it had protested against Russia's notification that Moscow would conduct missile tests off disputed islands visited by President Vladimir Putin earlier this month.

Why it matters

Bilateral relations have long been dogged by the Kuril islands, known in Japan as the Northern Territories and seized in 1945 by the Soviet Union which then expelled the Japanese population.

Common ground

"We lodged a protest in response to the notification about the plan to conduct a missile test" off the islands, a Japanese government spokesman told AFP.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
