The long Abe era and after · 2014–2026
Shinzō Abe's second premiership made the LDP-Komeito coalition look unshakeable through 2014 and 2017. After his assassination the ground shifted: the coalition lost its majority in 2024, and the snap election of February 2026 under Sanae Takaichi — Japan's first female prime minister — reset the board again.

Reform, upheaval and alternation · 1993–2012
The LDP's 1993 defeat ended 38 years of uninterrupted rule and brought electoral reform: single-member districts plus proportional blocks. Koizumi's 2005 landslide and the DPJ's historic 2009 victory showed the new system could produce both dominance and full alternation — before the 2012 wipeout brought Abe back.

The 1955 system · 1955–1990
The Liberal Democratic Party, formed in 1955, won every election for a generation, governing without interruption while the Socialists held a permanent second place. The '1955 system' delivered the economic miracle and one of the democratic world's longest runs of single-party dominance.

Occupation and the road to 1955 · 1946–1953
The 1946 election was the first with women's suffrage, held under Allied occupation with a new constitution ahead. Cabinets rose and fell — including Japan's only socialist-led government in 1947 — until conservative consolidation loomed.

Militarism and war · 1936–1942
Parties still contested the 1936 and 1937 elections even as cabinets answered to the military, not the Diet. By 1942 the parties had been dissolved into the Imperial Rule Assistance Association, and the wartime election was managed by the state — recorded here with that caveat.

Party cabinets and universal male suffrage · 1920–1932
The 1925 suffrage law quadrupled the electorate, and 1928 was the first election with universal male suffrage. For a decade Japan looked like a maturing parliamentary democracy, with the Seiyūkai and Minseitō alternating in power — until assassinations and the military's rise ended party government after 1932.

The Imperial Diet's first decades · 1890–1917
Japan's first general election in 1890 made it the first Asian nation with an elected national parliament — on a franchise of barely one percent of the population. The early Diet was a battleground between the Meiji oligarchs' governments and the political parties they refused to answer to.

How Japanese general elections work
Districts plus blocks
Since 1996 voters cast two ballots: one for a single-member district, one for a party in a regional proportional block. The mix replaced the old multi-member districts that had fuelled intra-party factionalism and money politics.
The Diet chooses the PM
The House of Representatives elects the Prime Minister, and its majority rules: governments in Japan have more often changed between elections, through party splits and coalition shuffles, than at them.
The 1955 system's long shadow
The LDP's merger in 1955 created a dominant party that has governed for all but roughly four of the past seventy years, usually with a coalition partner since 1999, a dominance no other G7 democracy matches.
Snap elections
The PM can dissolve the House at any time, and almost every election since the war has been a snap election, called at the government's moment of choosing, which is a large part of how the LDP's record was built.
