Japan and the Kural Islands in the 19th Century

During the Meiji era, even during the Tokugawa Shogonit era, Japan had started expanding in various directions. The Russians too had a policy of expansionism. But they expanded eastwards. And this entire Eurasian landmass that is currently part of Russia was all conquered by the Russians. They are essentially Tungusic people, two-one people, Siberian people, people who have Turkic ethnicity, Mongolic ethnicity and so on.
