Two weeks after securing the largest parliamentary majority for any Japanese party since 1955, Prime Minister Sanae Takaichi’s government is moving to implement the fiscal expansion that defined her election campaign. The 2026 budget, which had been delayed by the snap election, is expected to proceed through the Diet with minimal opposition resistance now that the LDP-JIP coalition controls 352 of 465 lower house seats and holds the two-thirds supermajority required to override the upper house.
The spending plan is ambitious by Japanese standards. The proposed budget includes record defense allocations that align with Takaichi’s commitment to strengthening Japan’s military capabilities, significant infrastructure investment to support rural economic development, and provisions for the potential two-year suspension of the consumption tax on food, a measure that would cost approximately 5 trillion yen ($32 billion) in foregone revenue. Takaichi stated at her post-election press conference that the government would “speed up discussions” on the food tax relief, a signal that the measure will advance despite the fiscal cost. Keidanren has expressed support for pro-growth spending while urging the government to maintain attention to fiscal sustainability.
Bond markets have responded with mounting concern. Japan’s 30-year government bond yield reached a record 3.88% ahead of the election and has remained elevated as the scale of the spending commitment becomes clearer. The yield curve steepening reflects a market recalibration: with Takaichi’s supermajority eliminating legislative checks on fiscal policy, investors are demanding higher compensation for holding long-dated Japanese government debt. The Bank of Japan’s gradual tightening cycle, which has included incremental rate increases aimed at normalizing monetary policy after years of ultra-loose conditions, adds an additional variable to the bond market equation.
The equity market, by contrast, has embraced the election outcome. The Nikkei 225 has maintained its post-election gains, supported by expectations that government spending will flow into sectors aligned with Takaichi’s policy priorities. Defense contractors, construction firms, and companies exposed to AI and semiconductor infrastructure investment have been among the primary beneficiaries. The weaker yen has provided an additional tailwind for exporters, with corporate earnings forecasts for the fiscal year beginning April 2026 reflecting improved yen-denominated revenue from overseas operations. Bank of America’s year-ahead framework targets the Nikkei at 55,500 by end-2026, while UBS has set a base case of 54,000.
The labor market and wage dynamics are particularly relevant for the macro outlook. Real wages have remained negative despite multiple consecutive months of nominal wage growth, a dynamic that constrains consumer spending even as the economy expands. The government is pursuing revisions to the Labor Standards Act designed to promote flexible work arrangements, including broader use of discretionary working hours, minimum rest intervals, and a two-week cap on consecutive workdays. Whether these reforms stimulate productivity or weaken worker protections has become a secondary policy debate that labor groups and opposition parties are monitoring closely.
The diplomatic calendar is adding another layer of market-relevant uncertainty. Takaichi’s planned visit to the White House on March 19 is expected to produce trade and defense commitments that will shape Japan-U.S. economic relations for the remainder of the year. President Trump has signaled interest in a “very substantial” deal covering both trade balances and security cooperation. Japan’s commitment to export U.S.-built vehicles to the domestic market, announced by Toyota, Honda, and Nissan in recent months, is part of the broader trade negotiation framework. For investors, the March summit will be a key catalyst for recalibrating expectations around tariffs, defense procurement, and bilateral investment flows.
The structural investment thesis for Japan has gained clarity. A government with an unchallenged parliamentary majority, committed to fiscal expansion and defense modernization, operating in an economy with improving corporate governance and sustained AI-driven technology investment, presents a coherent set of factors that support equity exposure. The offsetting risk, namely that fiscal expansion without revenue discipline will ultimately undermine government bond markets and weaken the yen beyond levels that benefit exporters, has not yet materialized as a binding constraint but is being priced into longer-duration fixed income. Investors should monitor the trajectory of JGB yields as closely as equity index levels in the months ahead.
