This chapter looks at the Japanese experience with judicial review. The Supreme Court of Japan does not enforce those parts of the Japanese Constitution, like Article 9, which prohibits war making; Article 21, which protects freedom of speech; or Article 89, which forbids taxpayer money from being used to hire Shinto priests. The Supreme Court of Japan thus refuses to enforce important articles in the Constitution of Japan. It does rubber stamp and thus legitimize actions taken by the political branches of the government. Why has judicial review of the constitutionality of legislation failed to take root in Japan? Japan does not need either a federal or a separation of powers umpire, since Japan is, firstly, a unitary nation-state with no need for a federalism umpire; and, secondly, a parliamentary democracy with a weak upper house of the legislature. Moreover, Japan has never atoned for the wrongs it committed during World War II nor has it truly admitted to even having done the horrible things that Japan did. A nation cannot get rights from wrongs judicial review and a Bill of Rights unless it admits it has done something wrong. Finally, the Japanese Constitution contains an inadequate system of checks and balances. As a result, the Supreme Court of Japan may not have the political space within which it can assert power.
