The 80000 Russian POWs from the Russo-Japanese War of 1905 were also treated very well. The Red Cross commended Japan for it.
Yes, that’s what I have read, too.
Even the few Russians on Sakhalin Island, which had been invaded by Japanese forces, were not mistreated by the victors.
In the treaty of Portsmouth 1905 Russia had to cede southern Sakhalin to the Japanese; but in 1945 Stalin reconquered it for the Soviet Union.
P.S.: President T. Roosevelt was awarded the Peace Nobel Prize for brokering the peace treaty between Russia and Japan.
I have no clue why, a generation later, the American and British prisoners of war were treated so badly by their Japanese captors at Bataan and, sadly, elsewhere…😞
