edm oorora tenko
Tenkō (転向, literally, changing direction) is a Japanese term referring to the ideological reversal of numerous Japanese socialists who, between 1925 and 1945, renounced the left and (in many cases) embraced the "national community." Tenkō was performed especially under duress, most often in police custody, and was a condition for release (although surveillance and harassment would continue). But it was also a broader phenomenon, a kind of cultural reorientation in the face of national crisis, that did not always involve direct repression.
For decades, the term served both narrowly as a moral litmus test in evaluating the careers of intellectuals active before and after the war and more broadly as a metaphor for the collective experience of an entire generation of Japanese. One of the most well known and consequential instances of Tenko came in June 1933, when Sano Manabu (1892—1953) and Nabeyama Sadachika (1901—1979), top figures in the Communist Party leadership, renounced their allegiance to the Comintern and the policy of violent revolution, embracing instead a Japan-specific mode of revolutionary change under imperial auspices, in reaction to the Soviet Union's use of the Comintern for its own power purposes against Germany and Japan.
Their proclamation was followed by a wave of defections by the party rank and file and essentially signaled the demise of the party organization, except in exile. Tenkō described a change in ideological position on the part of former anti-government radicals who had undergone self-criticism and who had returned to the ideological position supported by the state.
