Japan Faces First Economic Contraction in Six Quarters—Are U.S. Tariffs to Blame?
Tariff Shock Pushes Japan into Slowdown
Japan’s economy is on the brink of its first contraction in six quarters, as preliminary indicators suggest that GDP likely shrank 0.6% in real terms (2.5% annualized) in Q3 2025, according to a Reuters poll of 18 economists. This follows a 2.2% annualized expansion in Q2, signaling a sharp slowdown driven primarily by external pressures.
Analysts attribute the contraction largely to U.S. tariffs imposed on Japanese exports. When Washington and Tokyo reached a trade deal in July, the U.S. set tariffs at 15% on key imports, particularly autos, which remains far above the previous 2.5% rate, despite being lower than the initially threatened 27.5%.
Exports, Housing, and Inventory Investment Drag on Growth
Net exports—exports minus imports—were estimated to subtract 0.3 percentage points from Q3 GDP, reversing a 0.3-point contribution in Q2. The slowdown in foreign demand reflects a direct impact of tariffs on Japanese goods.
Other economic drags include:
Housing investment decline, following a strong rebound in Q2.
Inventory correction, as companies reduced stockpiles after front-loading shipments in prior months.
Stagnant private consumption, inching up just 0.1% in July-September, compared to 0.4% in April-June.
“The Japanese economy posted an expansion that could be almost called ‘too good’ through the first half of 2025,” analysts at SMBC Nikko Securities said. “However, with the weight of newly imposed tariffs coming to the fore, it was compelled to undergo a correction at least temporarily.”
Capital Expenditure Holds Steady, But Wage Pressure Persists
Despite external headwinds, capital expenditure growth remained modest at 0.3%, unchanged from the previous quarter. However, economic analysts caution that stagnating real wages are limiting personal consumption, suggesting that the economy may have entered a temporary stagnation phase, according to Saisuke Sakai, chief Japan economist at Mizuho Research & Technologies.
The combination of weak consumer spending, tepid investment, and export challenges highlights the vulnerability of Japan’s export-reliant economy, particularly in sectors like autos that are highly sensitive to U.S. tariffs.
Implications for Forex Traders
For Forex traders, these developments have important implications for the Japanese Yen (JPY). A contraction in Japan’s GDP, especially driven by exports and consumption, could:
Weaken the JPY against major currencies such as the USD (USD/JPY) or EUR (EUR/JPY).
Introduce short-term volatility as traders anticipate the impact of tariffs on corporate earnings and economic growth.

Bottom Line: Temporary Correction or Longer-Term Drag?
Japan’s Q3 contraction serves as a reminder that even robust economies are sensitive to trade disruptions. While the slowdown may be temporary, the impact of U.S. tariffs on autos and other exports is likely to linger, keeping investors and traders cautious.
Private consumption growth is slowing, wages remain stagnant, and net exports are under pressure—a combination that signals caution for the Japanese Yen in the Forex market over the coming months.
