1993 Japanese general election

General elections were held in Japan on 18 July 1993 to elect the 511 members of the House of Representatives. The Liberal Democratic Party (LDP), which had been in power since 1955, lost their majority in the House. An eight-party coalition government was formed and headed by Morihiro Hosokawa, the leader of the Japan New Party (JNP). The election result was profoundly important to Japan's domestic and foreign affairs.

It marked the first time under the 1955 System that the ruling coalition had been defeated, being replaced by a rainbow coalition of liberals, centrists and reformists. The change in government also marked a change in generational politics and political conduct; the election was widely seen as a backlash against corruption, pork-barrel spending and an inflated bureaucracy. Proposed electoral reforms also held much influence over the election. Eleven months after the election, with the electoral reform legislation that was its raison d'être passed, the eight-party coalition collapsed. This was the last general election to use the single non-transferable vote electoral system, with the 1994 electoral reform efforts changing the system to parallel voting starting with the next election.
