The Japanese word here is "kokutai", not identity.
Does Japan lack a sense of self and simply respond to changes from the outside? Advocates of constitutional revision blame the lack of a sense of identity -- within the Japanese state and among the people -- on the postwar Constitution.
How? Any gaijin here read the Japanese constitution? Maybe the right-wing would like to axe these "identity-damaging" sections:
