The Big Picture

Japan is facing its first genuine stagflationary dilemma in three decades. Growth is decelerating near its historical trend while inflation is accelerating — not because Japanese consumers are spending freely, but because an energy shock is driving up costs from the outside. The Iran war has pushed oil to $109 a barrel [3], and Japan imports roughly 90% of its energy. That cost pressure is flooding through a yen that has weakened to 156.64 per dollar [2].

Here is the contradiction at the center of Japan's economy right now: workers are getting the biggest pay raises in 35 years, and they are refusing to spend the money.

System view: Japan has achieved the first half of its "virtuous cycle" escape from deflation — wages are rising. But the second half — consumers actually spending those wages — has not materialized. The central bank is trying to raise interest rates for the first time in a generation, but an energy war and a falling currency are making every step treacherous. Confidence: moderate-low (60%). This view breaks if household spending turns positive for two consecutive quarters, which would confirm the virtuous cycle is complete, or if the yen collapses past 165, which would force the BoJ to abandon normalization entirely.

If you remember one thing from this report: Japanese workers are getting real raises for the first time in 30 years, but they are saving the money instead of spending it — and until that changes, the entire exit-from-deflation project hangs in the balance.

What the BoJ Is Doing and Why It Matters

Japan spent decades with interest rates at or below zero, trying to jolt the economy out of a deflationary spiral. Now the Bank of Japan is attempting something it has not done in a generation: raise rates into positive territory. Think of it as a patient learning to walk again after years in a wheelchair — the muscles exist, but the coordination is uncertain.

Where rates are. The BoJ's policy rate sits at 0.75%, having been held at the April 28 meeting by a 6-3 vote [5] — three dissenters (Nakagawa, Takata, Tamura) voted for an immediate hike to 1.00%. The decision to hold even as the bank raised its inflation forecast reflects caution about the energy shock, but the strong dissent signals that the majority's patience is wearing thin. The OECD projects the rate reaching 2% by the end of 2027 [7], which would mean roughly 1.25 percentage points of additional tightening over 18 months. The bank's own estimate of the "neutral" rate — the level that neither stimulates nor restrains the economy — was revised upward to a range of 1.1-2.5% in March [6].

Is the medicine working? Partially. The spring wage negotiations (called Shunto) delivered a 5.26% average raise — the largest since 1991, with even small and mid-sized firms getting above 5% [15,16]. Major companies like Toyota, Honda, and Hitachi fully met union demands [17]. Manufacturing hourly earnings are up nearly 6% year-over-year [12e]. Real wages (after adjusting for inflation) have been positive for three consecutive months [13e].

But here is the broken link: despite earning more, households cut spending by 1.8% year-over-year in February [8], and the share of income going to food hit a 44-year high [9]. Japanese snack manufacturers have even been forced to print packaging in black-and-white because the ink pigments — derived from petroleum — have become too expensive due to the Iran war [10e]. Workers are getting fatter paychecks and spending them on groceries that cost more, saving the rest out of caution. The BoJ needs a "virtuous cycle" where wages lead to spending, spending leads to inflation, and inflation justifies more rate hikes. Right now, the cycle is stalling at step two.

What comes next. A rate hike to 1.00% in June looks probable — wholesale price data spiked in April, giving the BoJ the data cover it needs, and three board members already voted for that level in April [6r]. After that, one more quarter-point increase to 1.25% by year-end is plausible, but only if household spending recovers. The risk is not the direction of rates — almost everyone agrees they are heading up — but the speed. Too fast and the economy buckles. Too slow and the yen keeps falling, making imports even more expensive.

The Economy Under the Hood

The growth story, in a sentence: Japan's economy is growing, but barely, and almost entirely because of exports and corporate activity — not because of domestic consumers.

GDP grew at an annualized 1.3% in Q4 2025 — narrowly avoiding a technical recession after a prior contraction [2g][3g]. The Q1 2026 estimate points to a slightly better 1.8% [4g]. For context, Japan's structural growth rate is about 0.8% per year, constrained by a population that is shrinking faster than almost any other developed nation. Nominal GDP has finally surpassed its 1997 peak [5g] — a milestone that took nearly three decades to achieve.

Corporate Japan is thriving. The Tankan business confidence survey for large manufacturers hit 17 in Q1 — the highest since late 2021 [9s]. Non-manufacturing sentiment reached a multi-decade high of 36. But this confidence predates the full impact of the Iran war energy shock. By April, business mood had already begun to sour as conflict-driven costs rose and corporate bankruptcies increased [10s].

The demographic headwind is relentless. This is the force that shapes everything else in Japan's economy. The working-age population (15-64) fell to 73.2 million in March [14g], shrinking by about 0.27% per month. Japan's child population dropped for the 45th consecutive year to 13.29 million — just 10.8% of the total [15g]. Adult incontinence products have outsold baby diapers for over a decade [16g]. The construction industry faces the retirement of 1.5 million skilled workers with productivity already below half of US levels [17g]. This is not a problem that policy can solve in any conventional timeframe — it is a permanent gravitational drag on growth.

The external lifeline. Japan posted a record current account surplus in 2025 [21g], but not because of trade. The surplus comes from returns on Japan's enormous overseas investments — the world's largest net foreign asset position. Actual merchandise trade swings between deficit and surplus. Exports surged 17% year-over-year in January, led by a 32% jump in shipments to China for AI and semiconductor components [23g]. But the energy import bill is about to surge: with the Hormuz Strait disrupted, Japan is scrambling for alternative oil supplies from Central Asia, Russia, and even pivoting back to coal [24g][25g][26g].

Assessment: Japan's economy is being kept above water by corporate confidence, export demand, and semiconductor investment (Rapidus, Sony-TSMC). The question is whether these cyclical tailwinds can outrun the demographic undertow and the energy cost shock. So far, the answer is "just barely."

What Could Go Wrong (and Right)

The gap between what financial markets are saying and what the real economy is doing has become Japan's defining feature. The Nikkei 225 stock index is up 62.65% year-over-year [12], hitting all-time highs — but that rally is largely a reflection of the depreciated yen making export profits look bigger in yen terms, not a signal of domestic economic vitality. Meanwhile, an estimated 20 trillion yen in yen-funded carry trades worldwide (where investors borrow cheaply in yen to invest elsewhere) creates a potential landmine: if the BoJ raises rates too abruptly, the unwinding of those trades could send shockwaves through global markets, as briefly happened in August 2024.

The probability distribution tilts 65% toward inflationary outcomes (cost spiral + currency crisis) versus just 10% for a return to deflation. The Iran energy shock is asymmetric — it is far more likely to push Japan toward overheating than toward the freezing temperatures of the lost decades.

What this means for different assets. Japanese government bonds at a 2.515% yield [13] are offering positive income for the first time in decades — attractive if you believe the smooth landing scenario, but exposed to capital losses if the BoJ tightens aggressively. The risk: if wholesale inflation keeps climbing and the BoJ is forced to hike past 1% by year-end, bond prices would fall further. The yen at 156.64 [2] is a coiled spring — it appreciates sharply in the smooth landing scenario as the rate gap with the US narrows, but collapses in the currency crisis scenario. The risk: if US rates stay elevated longer than expected while BoJ normalization stalls, the intervention floor gives way. Japanese stocks look exuberant at +62.65% [12], driven by governance reforms that have lifted corporate returns from a 2.57% trough to 11.66% [5f]. The risk: these gains correlate inversely with yen strength, meaning that if the BoJ successfully raises rates and the yen appreciates, the earnings translation boost evaporates. Property prices are up 5% nominally [9p] but have already peaked in inflation-adjusted terms — demographics will be an increasingly heavy drag, especially outside Tokyo. The risk: if mortgage rates rise materially, even nominal prices come under pressure.

Five things to watch, with specific trigger levels: 1. Yen past 160 for two or more weeks — every time this level has been breached, the government has intervened. Sustained weakness beyond it signals that intervention is failing and the currency crisis scenario is activating. 2. Services inflation rising above 3% — this would confirm that wage gains are transmitting to consumer prices, activating the cost spiral scenario. It is also, paradoxically, what the BoJ wants to see — just not this fast. 3. Household spending turning positive — two consecutive months of year-over-year gains would signal the virtuous cycle is completing. This is the single most important data point for the smooth landing scenario. 4. Tankan manufacturing confidence falling below zero — this index measures whether more firms are optimistic than pessimistic. A negative reading, combined with falling exports, would signal the back-to-deflation scenario. 5. Foreign exchange reserves dropping more than $50 billion — Japan has $1.25 trillion in reserves [7r], but sustained drawdowns at the pace of the recent $30 billion intervention [11] would raise questions about the government's ability to defend the yen.

The Leading Indicators

Scorecard: Of the seven key leading indicators, two are in critical or warning territory (bond yields and the credit gap), one is at warning (the yen), and four are elevated but not yet alarming. No indicators are in crisis territory.

The real-time verdict: The lagging indicators — unemployment at 2.8% [14], the BoJ's shrinking balance sheet, rising manufacturing wages — broadly confirm that Japan's exit from deflation is real. But the one prediction that has been flatly wrong is the expectation that higher wages would lead to higher spending. Until that changes, the entire normalization project remains half-built: the foundation is in place, but the structure above it is missing a load-bearing wall.
