The KÃ Âza school () was a group of Japanese Marxist historians active from the 1920s.
It stands out at the same time from another Marxist school, called Rà Ânà Â, on the analysis of the Meiji revolution. The Kà Âza group sees in the Meiji regime only an evolution of absolutism, based on a still archaic semi-feudal economy, while the Rà Ânà  group sees in it a bourgeois revolution and therefore places Japan in a dynamic comparable to this experienced by other developed countries.
