About the election

The ruling Liberal Democratic Party (LDP), now led by Prime Minister Fumio Kishida (see note 1), retained a majority in the 465-member House of Representatives. However, the LDP and its coalition partner Komeito lost their two-thirds majority. The new Constitutional Democratic Party of Japan (the main opposition party led by Mr. Yukio Edano, see note 2) reduced its share of seats from 110 to 96. By contrast, Nippon Ishin (the Japan Innovation Party), led by Mr. Ichiro Matsui, sharply increased its share of seats from 11 to 41 and became the third-largest force in the new legislature. On 10 November, the newly elected House of Representatives re-elected Mr. Kishida as Prime Minister.

The 2021 elections followed the Tokyo Olympic Games in August, which were held without audiences amid the global COVID-19 pandemic. During election campaigning, the major parties focused on the post-COVID economy, including a stimulus package, and lower taxes for middle and lower-income households. The LDP also pledged to drastically strengthen Japan’s defence capacity to deal with China’s military build-up.

Note 1:

The former foreign minister Fumio Kishida was elected as the new LDP leader in September 2021, and succeeded Prime Minister Yoshihide Suga on 4 October 2021. Mr. Suga had himself succeeded the former long-serving prime minister Shinzo Abe in September 2020.

Note 2:

The then Constitutional Democratic Party of Japan had won 54 seats at previous elections held in 2017. In September 2020, it relaunched as the new Constitutional Democratic Party of Japan without changing its name. The new party also included former members of the Democratic Party for the People, and some independents. It held 110 seats when the House of Representatives was dissolved in October 2021. Shortly before the 2021 elections, the new party announced a set of joint electoral pledges with three other parties: the Japanese Communist Party, the Social Democratic Party and Reiwa Shinsengumi.

Note on the timing of election :

The outgoing House of Representatives, elected in October 2017 for a four-year term, was dissolved on 14 October 2021, one week before the normal expiry of members’ terms. Although the 2021 elections were held after the normal expiry of members’ terms, they are considered as early elections following the dissolution of the House. Under article 31.1 of the Public Offices Election Law, elections must be held within 40 days of the dissolution.
