Japan’s Cabinet Office publishes the second preliminary (revised) reading of second-quarter 2026 gross domestic product on Tuesday, September 8, 2026, at 8:50am Japan Standard Time. That falls at 7:50pm ET on Monday, September 7 in New York and 12:50am London time on the 8th, because Japan is well ahead of both Western time zones. This revision covers economic activity across April to June 2026. For the full release calendar and background on how Japan reports growth, see Japan GDP.
What is Japan’s GDP report?
Gross domestic product measures the total value of goods and services produced in Japan over a period, usually reported quarter on quarter and then annualised, which extrapolates that quarterly pace over a full year as though it continued unchanged. The Cabinet Office’s Economic and Social Research Institute (ESRI) compiles the figures from spending, output and income data across households, businesses and government.
Japan releases GDP twice for each quarter. A first preliminary estimate comes roughly six weeks after the quarter ends, built on partial data. A second preliminary estimate follows around six weeks later, incorporating fuller corporate capital spending and inventory figures from the Ministry of Finance. The September 8 release is this second, revised estimate for Q2 2026.
Investors watch GDP because it is the broadest single gauge of whether an economy is expanding or contracting. For Japan specifically, the Bank of Japan weighs GDP trends, alongside inflation and wage data, when deciding whether conditions justify further interest rate moves after its long exit from ultra-loose policy.
When is the Q2 2026 GDP revision released?
The Cabinet Office releases the data at 8:50am JST on September 8, 2026, on the ESRI website. There is no scheduling uncertainty attached to this release: Japan’s Cabinet Office confirms exact GDP dates well in advance and has not flagged any change to this slot.
What is the consensus forecast?
A consensus forecast for the September 8 revision had not been published at the time of writing, since analyst polls for second preliminary GDP readings typically appear only in the days immediately before release. The number being revised is the first preliminary estimate published on August 17, 2026, which showed real GDP growing 0.3% quarter on quarter, or 1.1% annualised, according to Trading Economics. That missed economists’ prior expectations of 0.5% quarter on quarter and 2.0% annualised, and slowed from a downwardly revised 0.5% quarter-on-quarter (1.8% annualised) expansion in Q1 2026, per the same source.
| Measure | Prior (Q1 2026, revised) | First preliminary Q2 2026 |
|---|---|---|
| GDP, quarter on quarter | 0.5% | 0.3% |
| GDP, annualised | 1.8% | 1.1% |
What the result could mean
| Scenario | Likely market read | What it means in plain English |
|---|---|---|
| Revised above 0.3% QoQ | Yen could firm modestly if traders see it supporting further Bank of Japan tightening | The economy grew a bit faster than first thought, easing concern about a stalling recovery |
| Revised in line with 0.3% QoQ | Limited reaction, since the first estimate is already priced in | Growth confirmed as modest, dominated by exports rather than household spending |
| Revised below 0.3% QoQ, or negative | Yen could soften on reduced expectations of near-term rate rises | The economy grew less than reported, or shrank, adding to doubts about domestic demand |
These are possibilities, not predictions. Capital expenditure data due from the Ministry of Finance ahead of the release is the main swing factor, since business investment estimates get revised most heavily between the first and second GDP readings.
Why does this release matter right now?
The first preliminary reading showed private consumption, which accounts for more than half of Japanese GDP, flat quarter on quarter, its first non-positive reading in eight quarters, according to BigGo Finance. Growth was instead carried by net exports, which added 0.5 percentage points, while domestic demand subtracted 0.2 points. Trading Economics reported that economists expect private consumption to soften further in the third quarter as import costs and broader price pressures squeeze households. The Bank of Japan is watching whether wage gains, real compensation of employees rose 0.8% to 0.9% quarter on quarter in the first estimate, eventually feed through into stronger spending, a key condition it has cited for further policy normalisation.
What It Means for Your Money
Mortgages and borrowing: a stronger-than-expected GDP revision would support the case for the Bank of Japan to keep raising rates, which could push up variable-rate borrowing costs for Japanese households and businesses. A weaker revision reduces that pressure.
Savings: higher Japanese rates gradually improve returns on yen deposits, which have been unusually low for years, though any change from a single GDP revision is likely to be small.
Jobs and wages: soft consumption alongside rising real wages suggests households are saving rather than spending pay gains, a pattern worth watching if it persists into the third quarter.
Prices: the GDP deflator, a broad measure of price changes across the economy, rose 2.6% year on year in the first estimate, underscoring that inflation remains a live issue in Japan even as growth slows.
Investments, pensions and currencies: a weaker yen tends to follow disappointing growth data, which affects returns for anyone holding yen-denominated assets or funds with Japan exposure, while a firmer yen from a stronger revision can weigh on the earnings of Japan’s export-heavy companies when translated back into yen. Investors in Europe, the UK and Asia holding Japanese equities or bonds, directly or through pension funds, should note that GDP surprises can move both the currency and the Nikkei on the day.

What time is Japan’s GDP released?
The Cabinet Office publishes the data at 8:50am Japan Standard Time, which is 7:50pm ET the previous evening and 12:50am in London.
Why does Japan release GDP twice per quarter?
The first preliminary estimate uses partial data available about six weeks after the quarter ends, while the second preliminary estimate, released roughly six weeks later, incorporates fuller corporate investment and inventory data.
How does GDP affect Bank of Japan policy?
The Bank of Japan considers GDP growth alongside inflation and wages when judging whether the economy can sustain higher interest rates, so weaker growth tends to reduce expectations of near-term tightening.
Where is the official GDP release published?
Japan’s Cabinet Office publishes the data through its Economic and Social Research Institute (ESRI) website.
When is the next Japan GDP release?
The first preliminary estimate for Q3 2026 GDP is typically due around mid-November 2026, roughly six weeks after the quarter ends, consistent with Japan’s usual publication pattern.
