Japan's Ministry of Economy, Trade and Industry (METI) has formally submitted its budget request for fiscal year 2027, totaling a historic ¥7.8 trillion (approximately $490 billion), marking a record high for the ministry. This figure already surpasses the combined total of the current fiscal year's initial budget and the previous year's supplementary budget, which together stood at ¥5.27 trillion, underscoring an unprecedented acceleration in state-led strategic investment targeting semiconductors and artificial intelligence.

The sheer scale of this request partly stems from a significant overhaul in Japan's budget formulation process. The new system permits each ministry to submit proposals in a single round without spending ceilings, aiming to reduce reliance on ad-hoc supplementary budgets. METI official Hiroko Tamai noted in a briefing that the requested amount has already overtaken the total funds allocated to the ministry for the current fiscal year.

Billions for Strategic Pillars: AI, Semiconductors, Rare Earths, and Defense

This budget request serves as the concrete implementation of Prime Minister Takaichi Sanae's previously outlined 14-year, ¥370 trillion public-private investment plan. Of the ¥7.8 trillion total, ¥6.31 trillion is earmarked under the "Strong and Prosperous Japan" investment framework, reflecting the core policy direction of Takaichi's push to revive the economy and upgrade strategic industries. Earlier, Takaichi had called for a combined ¥370 trillion (around $2.3 trillion) in public and private sector investment across priority industries over the next 14 years. The plan, formally adopted through the cabinet's "Basic Policy" in July this year, positions 17 strategic domains—including AI, semiconductors, quantum computing, and next-generation energy—as the foundation for future economic growth.

AI, semiconductors, and robotics receive approximately ¥2 trillion, the single largest allocation category in this request. Among these, Rapidus, Japan's "national champion" in chipmaking, stands to receive around ¥944 billion in additional funding, targeting mass production of 2-nanometer chips by 2027. The competitive landscape Rapidus faces is intense—Taiwan Semiconductor Manufacturing has already begun mass production of 2nm chips in 2025, and Elon Musk is collaborating with Intel on the "Terafab" project. Critical mineral security receives ¥680 billion, aimed at ensuring stable supplies of strategic resources like rare earths. Given the heavy concentration of the global rare earth supply chain in China, Japan is accelerating efforts to establish a self-reliant resource security framework. Naphtha supply capacity gets ¥220 billion to bolster the resilience of petrochemical supply chains. Defense and dual-use capabilities receive ¥180 billion, in partnership with the Defense Ministry to enhance defense-related technology. These areas directly mirror Japan's geopolitical and economic security challenges—great power competition over key technologies, energy supply disruptions stemming from the Iran war, and rare earth supply chains emerging as a focal point of geopolitical maneuvering.

Key Focus: Japan's Role in the Global AI Chip Race

METI's budget request serves as a concentrated reflection of Japan's repositioning within the global semiconductor and AI competition. From Rapidus's 2nm mass-production plans to the operation of Taiwan Semiconductor Manufacturing's Kumamoto plant, Japan is seeking to rebuild its central position in the global semiconductor landscape. Rapidus's production timeline is clearly set: start 2nm process manufacturing in the latter half of fiscal year 2027 and achieve full-scale mass production by fiscal year 2028. The company plans to offer foundry services at ¥3.0 to ¥3.5 million per wafer, roughly $10,000 cheaper than Taiwan Semiconductor Manufacturing's quoted price of around $30,000 per wafer for 2nm. However, the road to catching up remains steep. Taiwan Semiconductor Manufacturing's 2nm capacity has already been fully booked for this year by clients including Apple and Qualcomm, with four plants producing up to 60,000 wafers per month and trial production yields exceeding 70%. Rapidus is starting later and its manufacturing scale is only about one-third of Taiwan Semiconductor Manufacturing's.

Fiscal Hurdles: The Difficult Balancing Act of Debt and Policy

The greatest constraint on this strategic bet comes from Japan's precarious fiscal state. As the world's most indebted developed economy, whether Japan can fund these investments without further worsening its finances remains the central question. For fiscal year 2027, the general account budget is projected to exceed ¥140 trillion, setting a record high for the fourth consecutive year. Among this, the Finance Ministry's request for "national debt service" alone amounts to ¥36.6 trillion, covering interest payments and redemption of maturing principal. The Takaichi administration also faces the challenge of policy balancing. Although inflation has boosted government tax revenues, Takaichi plans to cut the consumption tax on food for two years without relying on debt-financing bonds, complicating the task of balancing competing interests. Against the backdrop of inflation lifted tax revenues, finding equilibrium among strategic investment, household relief, and fiscal discipline will become the core policy battleground for Japanese fiscal policy in the coming months. The Bank of Japan is advancing monetary policy normalization while the government simultaneously pursues large-scale fiscal expansion—this divergence in direction could place fresh pressure on Japan's government bond market. Meanwhile, markets are closely watching how the Finance Ministry will strike a balance between "proactive fiscal policy" and "fiscal discipline."
