Answer:
Japan fought against and defeated Russia.
Step-by-step explanation:
The conflict was the Russo-Japanese War of 1904-1905. The best known and one of the most spectacular actions of the war was the sinking of the Russian Baltic fleet at the battle of Tsushima in May 1905, the first modern sea battle with the participation of steel warships . The Russian fleet had crossed half of the world to reach the Northern Pacific. It was a tragic outcome, a shock and a huge humilliation for tsarist Russia. Since then, Japan was seen as a member of the exclusive club of great powers.
