About elections in Japan
I'm Bartłomiej Paruzel, and I built ElectioMap to map national elections around the world. This is the Japan hub on ElectioMap — it brings together the 8 Japan elections I cover, each with the official results, vote and turnout shares to two decimal places, and, where the electoral authority publishes an official regional breakdown, an interactive map you can explore region by region.
Japan is a constitutional monarchy and parliamentary democracy. The bicameral Diet consists of the 465-seat House of Representatives (lower house) and the 248-seat House of Councillors (upper house). The lower house is elected every four years (or sooner if dissolved) using a parallel mixed-member system: 289 seats by FPTP from single-member constituencies and 176 seats by proportional representation from 11 regional blocs. The prime minister leads the executive and is chosen by the lower house. Japan has been governed for most of its postwar history by the Liberal Democratic Party (LDP), a broad centre-right grouping that dominated politics almost uninterruptedly from 1955 to 2009 and again from 2012 to the present. Key opposition forces include the Constitutional Democratic Party (CDP, social-democratic), Nippon Ishin no Kai (Japan Innovation Party, regional/liberal), and the Democratic Party for the People (DPP). Following the LDP's losses in October 2024 over a political fundraising scandal, Sanae Takaichi became prime minister and called a snap election in February 2026, in which the LDP won a commanding supermajority of 316 of 465 seats. Japan faces structural challenges including an ageing and shrinking population, record public debt, energy transition, and managing its security relationship with the US amid regional tensions with China and North Korea. The Ministry of Internal Affairs and Communications (soumu.go.jp) administers elections.
Each election listed here has its own page with the full breakdown by party or candidate and an interactive map of the result.
Every figure on ElectioMap is taken from the official electoral authority for Japan — the national election commission or equivalent body that certifies the count. I enter vote and turnout percentages exactly as published, to two decimal places and without rounding, and show seat totals wherever a chamber is being filled. When ElectioMap covers an election live, the page updates automatically as official figures are released. For the full sourcing and update policy, see Data & Methodology and the Editorial Policy.

Where the electoral authority publishes an official regional breakdown, the Japan election page includes an interactive map — click a region to see how each party or candidate performed there. Where no official per-region data exists, the page shows the certified national result and says so.
