Moody’s Ratings sees encouraging signs that Japan is emerging from decades of weak economic growth and persistently low inflation, but the sustainability of that recovery is significantly tied to the economy’s ability to withstand future shocks and the government’s capacity to address long-standing structural weaknesses.
Martin Petch, a vice president in Moody’s sovereign risk group and its Japan sovereign analyst, told Reuters on Tuesday that growth was beginning to look more durable, while inflation expectations had become better anchored around the Bank of Japan’s 2% target.
“We’re starting to see what looks more like sustained growth and inflation expectations that are reasonably well anchored around 2%,” Petch said.

“That’s been something that’s changed,” he added, referring to the shift away from an economic environment characterized by sluggish growth and chronically low inflation.
The assessment points to a potentially important change in Japan’s economic outlook. For years, weak domestic demand and subdued price increases constrained the country’s ability to generate stronger nominal growth. A more stable inflation environment, accompanied by sustained economic expansion, could improve business investment incentives, support wages and strengthen government revenues.
However, Moody’s is not yet treating the change as proof that Japan has permanently overcome its structural problems. The rating agency is watching to see if recent economic improvements can endure, alongside reforms intended to raise productivity and mitigate the effects of an ageing population and declining workforce.
Moody’s rates Japan at A1, its fifth-highest investment-grade rating, with a stable outlook. The rating has remained unchanged since the agency downgraded the country from Aa3 in 2014.
Petch declined to speculate on future rating decisions but identified the economy’s response to future disruptions as a critical test of its resilience.
“You can generally tell when growth has become sustained when the economy has dealt with a shock,” he said.
He pointed to Japan’s response to recent energy-price shocks as an encouraging sign, while noting that the Bank of Japan has continued efforts to normalize monetary policy.
A recovery that survives higher energy costs, tighter monetary conditions or weaker external demand would provide stronger evidence of economic resilience than growth recorded under favorable conditions alone.
Japan’s improving economic outlook is unfolding alongside renewed debate over government spending, taxation and the country’s fiscal position.
Prime Minister Sanae Takaichi’s proposed cut to the food sales tax and ambitious spending plans unsettled bond markets this year, raising concerns about the potential effect on public finances. Petch nevertheless suggested that the measures posed little immediate threat to Japan’s sovereign credit profile.
The ultimate impact, he said, would depend on whether the government delivered on its commitment to offset the revenue lost through the tax reduction.
That condition places fiscal implementation at the center of the credit assessment. A tax cut could support household purchasing power, particularly if food prices remain elevated, but it would also reduce government revenue unless offset by spending adjustments or alternative sources of funding.
The issue significantly matters to Japan, where an ageing population and substantial public debt limit the room for policy mistakes. Measures intended to stimulate demand may offer near-term support, but their longer-term consequences will be determined by their ability to generate sufficient economic benefits to justify their fiscal cost.
Japan’s ministries have requested a record 143 trillion yen, equivalent to approximately $908 billion, in initial spending allocations. Petch said the increase appeared relatively modest when compared with the combined initial and supplementary budgets, reinforcing Moody’s view that the government had not meaningfully abandoned its recent fiscal consolidation trend.
The contrast between initial budget requests and total spending has grown wider. A record headline figure does not necessarily establish that the government has embarked on a substantial new expansion of expenditure. The more relevant assessment is how final spending compares with previous budgets, how much is financed through additional borrowing and whether the government maintains credible plans to manage its debt burden.
Still, the agency is watching how the government’s policy commitments develop. If tax reductions and new spending are not matched by credible financing measures, the resulting pressure on public finances could complicate the country’s efforts to preserve its credit standing.
Uncertainty also surrounds the government’s proposed 370 trillion yen public-private investment initiative. Petch said key questions include how much private-sector capital the programme attracts and whether the investments produce the productivity improvements needed to offset Japan’s demographic challenges.
The initiative’s headline value alone will not determine its economic contribution. Its effectiveness, according to analysts, will be based on the projects selected, the allocation of risk between the public and private sectors and whether the spending expands productive capacity rather than simply shifting existing investment between participants.
Japan faces a shrinking and ageing population, which threatens to constrain labor supply, increase pressure on public spending and limit the economy’s potential growth rate. Improving productivity could help counter those effects by enabling businesses to produce more output with fewer workers and by supporting higher wages and corporate earnings.
This means that private investment could contribute through automation, technological innovation, infrastructure upgrades and improvements in business efficiency. But those benefits are not automatic. If private companies remain reluctant to participate or projects fail to generate meaningful productivity gains, the initiative may deliver less economic value than its scale suggests.
For Moody’s, the relationship between investment and productivity has become key to Japan’s long-term credit prospects. Stronger growth can help stabilize public finances by increasing the tax base, while more efficient use of labor and capital could make the economy better equipped to manage demographic pressures.
The Bank of Japan’s monetary policy transition adds another dimension to the outlook. Moving away from an extended period of exceptionally accommodative policy is consistent with an economy experiencing more durable inflation, but it also creates a test of how well households, businesses and financial markets adjust to changing borrowing costs.
The broader question is whether Japan can sustain growth without relying excessively on fiscal stimulus or allowing rising financing costs to undermine public finances.
Moody’s current assessment indicates that the country’s economic recovery is encouraging enough to support its existing sovereign rating, but not sufficient to remove longer-term concerns.
