The Left in Japan can never defeat the Right in power by letting the Right argue, and arguing themselves, that the Right represent patriotism and nationalism, that they are opposed to the Right because they are opposed to patriotism and nationalism, and that they support the constitution drawn up by the US occupation authorities. The post-war Right in Japan have never been patriotic and nationalistic in any meaningful sense of the words -- the post-war Right in Japan have only been subservient to Washington, and such "patriotism and nationalism" as they display means nothing but chauvinism toward their fellow Asians. Why let the Right pass themselves off as patriots and nationalists?
The problem of post-war politics in Japan is that all major political parties and currents, on the Left, the Right, and the Center, are pro-Washington. Their ideology, and more damagingly the structure of feeling, is Datsua Nyuo, Out of Asia, Into the West.* The Left in Japan should have rejected the constitution a long time ago and called for a constituent assembly to draw up a new one, on the simple ground that _the people of Japan had no part in writing it_, and in that context argued for Datsuo, Nyua, a new foreign policy of independence from the West and equality and friendship with Asia, especially China, Korea, Russia, and the Middle East.
In education, the Left in Japan should argue for giving students choice in learning a range of foreign languages, abolishing the long-standing policy of English-only foreign-language education in public schools.
* In this Japan is very much like Turkey, where the mainstream political discourse has the Turks reject the Arabs, the Kurds, the Iranians, and others in the region and seek to join America and Europe. In Japan, the earliest proponent of this anti-Asian ideology is said to be Fukuzawa Yukichi, who wrote Datsua Ron, On Leaving Asia: <http://en.wikipedia.org/wiki/Datsu-A_Ron>. -- Yoshie
