Japanese Prime Minister Sanae Takaichi's Coalition Secures Supermajority in Snap Election

Japanese Prime Minister Sanae Takaichi Secures Supermajority in Snap Election

Japanese Prime Minister Sanae Takaichi, the nation's first female leader, called for early parliamentary elections in February, three months into her term. The election, held on February 8, resulted in her ruling coalition, comprising the Liberal Democratic Party (LDP) and the Japan Innovation Party (JIP), securing a two-thirds supermajority in the House of Representatives. This outcome, largely attributed to Ms. Takaichi's high personal approval ratings, grants the government significant legislative power to advance its agenda. This agenda includes economic reforms, increased defense spending, and potential constitutional revisions, amidst market concerns over fiscal policy and ongoing diplomatic tensions with China.

The ruling coalition's two-thirds supermajority empowers the Takaichi administration to push forward with ambitious reforms, including significant constitutional changes.

Background: A Swift Rise and a Risky Bet

Sanae Takaichi assumed the prime ministership in late October, becoming Japan's first woman to hold the office. Her appointment followed the Liberal Democratic Party's loss of its absolute majority in the 2024 general election. This setback led to the LDP's long-standing coalition partner, Komeito, abandoning the alliance in October over policy differences. Ms. Takaichi subsequently formed a new governing coalition with the Japan Innovation Party. At the time, the LDP, with its new coalition partner and support from independents, held a narrow majority in the 465-seat Lower House and was a minority in the 250-seat Upper House.

On January 23, Ms. Takaichi announced her intention to dissolve parliament, leading to a snap general election scheduled for February 8. This marked Japan's first winter election in 36 years. Her stated objectives were to leverage her personal popularity, which consistently polled between 60% and 80%, to strengthen her government's position, secure a public mandate for her policies, and potentially restore the LDP's absolute majority.

Takaichi's Ambitious Agenda: Policy Proposals and Global Stance

During her initial months in office and the subsequent election campaign, Prime Minister Takaichi outlined several key policy proposals.

Her economic plans included abolishing a special gasoline tax, implementing energy and fuel subsidies, and proposing broader tax cuts. A significant proposal was a two-year suspension of the 8% consumption tax on food items, estimated to reduce annual government revenue by 5 trillion yen ($47 billion). Ms. Takaichi reaffirmed her intention to proceed with this plan after the election. She also advocated for increased government spending, echoing the "Abenomics" stimulus measures of former Prime Minister Shinzo Abe, and committed to a "responsible yet aggressive" fiscal policy, largely to be funded through bond issuance.

Ms. Takaichi emphasized a firm stance on national security, including an accelerated defense build-up. Her administration approved a record defense budget of nine trillion yen ($57 billion) in December and committed to increasing defense spending to 2 percent of GDP from decades of capping it at 1 percent. She also expressed a willingness to revise security and defense policies, potentially expanding arms exports. A central goal for her and the LDP is to revise Japan's post-World War II pacifist Constitution, particularly Article 9, which renounces the right to wage war. Other potential reforms include enhancing intelligence capabilities, removing restrictions on defense equipment exports, and reviewing policies concerning nuclear weapons.

Ms. Takaichi's premiership has been marked by heightened tensions with China. In November, she made comments suggesting potential Japanese military involvement in a China-Taiwan conflict if Japan's security were compromised, describing such a scenario as an "existential crisis" or "survival-threatening situation" for Japan. China responded by imposing trade restrictions, including bans on Japanese seafood imports and rare earth mineral exports, and issuing travel warnings. Conversely, Ms. Takaichi has pursued closer ties with the United States, receiving an endorsement from former U.S. President Donald Trump ahead of the election. Ms. Takaichi is scheduled to meet with Mr. Trump at the White House on March 19.

The Campaign Trail: Domestic Concerns and Political Alliances

Despite Ms. Takaichi's high personal approval ratings, the Liberal Democratic Party's broader popularity remained around 30% and had been affected by political funding scandals and past associations with the Unification Church. Domestically, rising cost of living was cited by 45% of respondents in an NHK poll as their primary concern.

In response to the snap election, Japan's two largest opposition parties, the Constitutional Democratic Party of Japan (CDPJ) and the Komeito party (a former LDP coalition partner), formed the Centrist Reform Alliance to campaign together. Ms. Takaichi, considered a hardline conservative and a protégé of former Prime Minister Shinzo Abe, with a leadership style drawing comparisons to Margaret Thatcher, aimed to emphasize policy differences from her centrist predecessor. She also sought to appeal to voters who had shifted to right-wing parties, such as the populist Sanseito Party.

Throughout the campaign, Ms. Takaichi pledged to resign if her ruling coalition failed to secure a majority in the House of Representatives. Voting occurred amidst heavy snowfall in various regions, which some analysts suggested could impact voter participation. An estimated 27.02 million early ballots were cast, and overall voter turnout was estimated at 55.6% to 56.22%.

Landslide Victory: A Mandate for Change

On February 8, the LDP-JIP coalition secured a landslide victory. Exit polls and official counts projected the Liberal Democratic Party to win between 274 and 326 seats, surpassing the 233 seats required for a simple majority. Combined with the Japan Innovation Party, which won 36 seats, the coalition secured at least 310 seats (totaling around 352 seats), achieving a two-thirds supermajority in the 465-member lower house. This outcome represented the LDP's largest majority since its founding in 1955 and the first time a single Japanese party achieved a lower house supermajority in the post-war era since 1947.

The LDP-JIP coalition's historic two-thirds supermajority marks the largest LDP majority since 1955.

The Centrist Reform Alliance, the main opposition group, experienced substantial seat losses. Its leaders resigned following the results. The far-right populist Sanseito party gained several seats, and Team Mirai, advocating for digital political participation, secured its first seat. The supermajority provides the Takaichi administration with the authority to override vetoes from the opposition-controlled upper house and initiate processes for potential amendments to Japan’s Constitution. Following the results, Prime Minister Takaichi stated her commitment to fiscal sustainability and confirmed that the LDP's coalition with the JIP would continue. International leaders, including the U.S. Ambassador to Japan and Taiwan President Lai Ching-te, extended congratulations.

Post-Election Landscape: Market Reactions and Next Steps

Following the election results, Japan's Nikkei 225 index reached a record high, while Japanese government bonds experienced a selloff, and the yen weakened. The yield on Japan's 10-year government bonds reached a 27-year high, with 10-year yields increasing by six basis points to 2.282% and 30-year yields rising by four basis points to 3.55%. The yen depreciated by approximately 6% against the U.S. dollar since Ms. Takaichi's election in October, trading around 157 to the U.S. dollar in early post-election trading.

Market participants expressed concerns regarding the funding of Ms. Takaichi's proposed stimulus spending and tax cuts, particularly the consumption tax suspension, given Japan's significant national debt, which exceeds 200% of its GDP. Ms. Takaichi, however, reaffirmed her intention to proceed with the tax cut plan, while also committing to "responsible and proactive fiscal policy."

On the Wednesday following the election, Prime Minister Takaichi and her cabinet collectively resigned. This action is a procedural step preceding a special parliamentary session where Ms. Takaichi is widely anticipated to be re-elected as prime minister, given the ruling coalition's overwhelming majority in the lower house. Significant changes to the cabinet lineup are not anticipated as the current cabinet was appointed only months prior. The special Diet session is scheduled to continue for 150 days, concluding on July 17.
