Repeated disappearance: why was progressivism forgotten in Japanese economics?

The introduction of Progressivism in Japan began with the social reform of Katayama Sen, influenced by Richard Theodore Ely. Katayama’s coordinated labor market reforms were repressed by the government of time, and Katayama’s position changed to radical socialism and moved away from Progressivism. Japan’s Association for the Study for Social Policy emphasized a national-centric social policy and ignored Katayama’s Progressivism contribution. Kawakami Hajime translated the American economist’s writings during the Progressivism era and actively enlightened their achievements. However, Kawakami abandoned the Progressivism position and moved to the Marxian economics position while emphasizing the poverty of workers. Fukuda Tokuzo, an adversary of Kawakami, proposed Progressivism-like Welfare Economics. But Fukuda’s Welfare Economics was incomplete, and no successor to his work appeared. Though American Progressivism was imported in the same period as Japan, by the stoppage of repeated research programs, it was over as predigestion. This produced the specific bias which remains until today in Japanese economics.
