 The main issue for the opposition parties was electoral reform.Additionally, there was general consensus on some other issues, including tax cuts which are needed to stimulate economic growth and anti-corruption measures.The Social Democratic Party of Japan (SDPJ) even relaxed several long-held positions - that was recognition of the constitutionality of Japan's Self-Defense Force, acceptance of the peace treaty with the Republic of Korea and approval of nuclear energy until alternatives are developed - so as to “put an end to the LDP’s monopoly of politics and establish a coalition government to accomplish political reform,” according to SDPJ Chairman Sadao Yamahana.
