Hayao Miyazakis new film is already a box office hit but its themes about the dangers of nationalism and war have set up the Oscar-winning animator for unprecedented criticism. The Wind Rises is based on the man who designed Japans feared Zero fighter plane used in World War Two. Commentators see it as a warning that Japan may again be heading in a similar direction. Miyazaki,72,emphasised that warning in a scathing essay in mid-July about proposals by PM Shinzo Abe to revise Japans pacifist constitution.
