Surely a disagreement within the LDP-Komeito coalition on constitution revision and the related question of collective self-defense is not insignificant, given the priority Prime Minister Abe has given these issues. Since the LDP does not hold the necesssary two-thirds majority in either house that it would need to pass constitution revisions, Komeito’s support may be the deciding factor in whether and how the Abe Cabinet decides to push forward on constitution revision. I suspect that opposition from Komeito — the political affiliate of the Buddhist Soka Gakkai organization, which believes in a kind of conservative pacifism — might temper the ultimate shape of a revised constitution, if revisions manage to take shape under the Abe Cabinet.
Perhaps the prospect of all of Japan’s political parties uniting against Abe’s government would be enough stop his efforts — or at least make the government substantially more deferential to the wishes of the Japanese public and opinions from across spectrum of the Japanese political system.
Yet another reason for observers not to overreact to steps being taken towards constitution revision.
