Japan Approves Record ¥122 Trillion Budget as Takaichi Seeks Growth Without Debt Shock

Japan’s government on Friday approved a record ¥122.3 trillion ($785 billion) budget for the next fiscal year, underscoring Prime Minister Sanae Takaichi’s attempt to walk a tightrope between stimulating the economy and reassuring markets worried about the country’s already massive public debt.

The budget, which covers the fiscal year beginning in April and will be submitted to parliament early next year, is the largest in Japan’s history. It comes at a time when rising government bond yields, a weakening yen, and the Bank of Japan’s gradual exit from ultra-loose monetary policy have heightened investor sensitivity to fiscal discipline.

Limited Bond Issuance to Calm Markets

Despite the record size of the budget, the Takaichi administration has kept a tight rein on new debt issuance. New government bond sales are set to rise only marginally—from ¥28.6 trillion this year to ¥29.6 trillion—a move officials say reflects a conscious effort to avoid alarming bond markets.

As a result, the government’s debt dependence ratio—the share of spending financed by bond issuance—is projected to fall to 24.2%, its lowest level since 1998. Senior finance officials said this was intended to signal that Japan is not returning to unchecked borrowing or politically popular but fiscally risky tax cuts.

Revenue Growth Helps Offset Rising Costs

A key pillar of the budget strategy is stronger tax revenue. The government expects tax receipts to increase 7.6% to a record ¥83.7 trillion, providing crucial funding for expanded spending.

However, revenue gains will not fully offset rapidly rising costs. Debt servicing—covering both interest payments and redemptions—is projected to climb 10.8% to ¥31.3 trillion. The assumed interest rate for government borrowing has been set at 3.0%, the highest in nearly three decades, reflecting the Bank of Japan’s policy shift away from years of aggressive monetary easing.

In addition to debt servicing, spending pressures are rising from social welfare commitments tied to Japan’s ageing population and from higher defence outlays amid regional security concerns.

Debt Burden Remains a Structural Risk

Japan already carries the highest public debt burden among advanced economies, with government debt exceeding 200% of GDP. Economists warn that this makes the country particularly vulnerable to even modest increases in borrowing costs.

“Japan can still fund itself domestically, but rising yields change the calculus,” said a Tokyo-based economist. “The margin for policy error is smaller than it was when rates were near zero.”

These constraints complicate Prime Minister Takaichi’s broader economic agenda, which leans toward proactive fiscal support to sustain growth and cushion households from inflation.

Rethinking Fiscal Rules

In a notable policy shift, Takaichi has signalled plans to move away from Japan’s long-standing reliance on the annual primary budget balance as the main yardstick for fiscal consolidation. Instead, her government is considering a multi-year framework that would allow more flexibility in spending while still aiming for medium-term sustainability.

Supporters argue that such an approach better reflects economic realities in a country facing demographic decline and structural growth challenges. Critics, however, caution that loosening fiscal targets could undermine hard-won market confidence if not clearly defined.

What It Means Going Forward

The budget highlights Japan’s central dilemma: how to support economic growth and social stability without triggering a loss of confidence in its public finances. By pairing record spending with restrained bond issuance, the Takaichi government is betting it can do both—at least for now.

Much will depend on whether tax revenues materialise as projected, how quickly interest rates rise, and whether markets continue to believe that Japan’s fiscal expansion remains under control in a new, less accommodative monetary era.
