The Brief

Revised figures released Tuesday showed Japan’s economy grew at an annualized 1.3% in the fourth quarter of 2025 — six times the preliminary 0.2% estimate — driven by the strongest business capital expenditure since late 2023. Household spending fell 1.0% in January against expectations of a 2.5% rise, and the escalating Iran conflict now clouds the outlook for an economy that imports 90% of its oil from the Middle East.

The Report

Japan’s Cabinet Office revised fourth-quarter GDP sharply higher on Tuesday, reporting annualized growth of 1.3% against the initial estimate of 0.2% released in February. The revision, which slightly exceeded the median economist forecast of 1.2%, reflected a substantial upgrade to business capital expenditure and a modest improvement in private consumption.

Capital spending rose 1.3% quarter-on-quarter — the largest increase since October–December 2023 — revised up from a preliminary 0.2% and beating the consensus forecast of 1.1%. The improvement marks the fourth consecutive quarterly gain in corporate investment, supported by government tax credits and subsidies targeting semiconductors, AI, and advanced manufacturing. TSMC’s $17 billion upgrade to its Kumamoto fabrication facility for 3nm chips represents the most visible single commitment.

Private consumption, which accounts for more than half of Japan’s economy, was revised up to 0.3% growth from 0.1%. Domestic demand’s contribution to GDP rose to 0.3 percentage points from zero. External demand — exports minus imports — contributed nothing, unchanged from the preliminary reading, with both exports and imports contracting 0.3%.

The revision brought the figure closer to where analysts had expected it to be before the preliminary disappointed. The Japan Center for Economic Research’s pre-release consensus had been 1.48% annualized — meaning the revised 1.3% remains slightly below the market’s original expectation, and the preliminary 0.2% was the statistical anomaly.

The stronger backward-looking data arrives alongside forward-looking warning signs. Household spending fell 1.0% year-on-year in January, diverging sharply from market expectations of a 2.5% increase. Real wages rose 1.4% in the same month — the first gain in thirteen months, powered by base salary growth of 3.0%, the fastest since October 1992 — but the spending data suggests households remain cautious despite fatter pay packets.

Takeshi Minami, chief economist at the Norinchukin Research Institute, warned that “after April, if energy imports remain disrupted due to the Iran conflict, higher prices could hit consumption.” Bank of Japan Governor Kazuo Ueda told parliament on March 4 that the conflict “could have a significant impact on the global economy and Japan’s economy” through energy prices and financial markets. Japan sources roughly 90% of its oil imports from the Middle East.

The BOJ, which raised rates to a 30-year high of 0.75% in December, is widely expected to hold at its March 18–19 meeting. Market pricing puts the probability of an April hike at around 60%, though Prime Minister Sanae Takaichi — who secured a historic two-thirds lower house majority in February’s snap election — has since appointed two monetary doves to the BOJ board. Nominal GDP for 2025 stood at 663.8 trillion yen, or approximately $4.2 trillion, as India approaches Japan’s position as the world’s fourth-largest economy.

The Angle

The headline — growth six times higher than first reported — tells a story about a dramatic upgrade. The data tells a different one. The JCER consensus before the preliminary release was 1.48%. The revised figure is 1.3%. What happened in February was not that Japan’s economy was weak. It was that Japan’s statistical apparatus produced a preliminary estimate so far from reality that the correction looked like a breakthrough. The anomaly was the 0.2%, not the 1.3%.

That distinction matters because the actual picture it reveals is less comfortable than either reading suggests. Business investment is carrying Japan’s GDP almost single-handedly — the strongest capex since late 2023, driven substantially by semiconductor subsidies and a single foreign chipmaker’s factory expansion. Private consumption revised up to 0.3% is not momentum. It is a rounding error in an economy where consumers just posted a 1.0% spending decline in January despite real wages turning positive for the first time in over a year. Workers are earning more and spending less. That is not confidence. That is preparation.

The structural tension is now visible enough to be worth naming. Takaichi has a supermajority, a $139 billion stimulus package, and a BOJ board she is reshaping in her preferred direction. The economy is producing the capex numbers that justify optimism and the consumption numbers that justify caution, simultaneously. And threading through all of it is a variable no domestic policy can address: an energy supply chain that runs 90% through a region currently at war. The revised GDP is a better photograph of where Japan was three months ago. The January spending data is a blurrier photograph of where it is heading.
