Former Democratic Party of Japan (DPJ) leader Ichiro Ozawa delivers a speech after submitting his resignation to the DPJ at the lower house members hall in Tokyo on July 2, 2012. 'Shadow Shogun' Ozawa and his 50-supporters stormed out of Japan's ruling party in protest at a sales tax hike, in a move that reduces, but does not overturn the government's majority.
