Recent Japanese political instability has complicated U.S.-Japan relations and posed new challenges to the achievement of important American economic, foreign policy and security objectives. Since July 1993 Japan has been governed by coalitions under three different prime ministers. The first coalition, under Prime Minister Morihiro Hosokawa, pushed through electoral and campaign finance reform legislation of potentially long-term significance, but failed to overcome political, bureaucratic and interest group resistance to its economic and administrative reform agenda. Its successor's have appeared to have progressively less power and will to carry out promised reforms or assume international leadership commensurate with Japan's global economic weight.
