BOJ September Tankan 2026: October 1 release time and what to watch

Release time, status and worldwide conversions

Confirmed: the Bank of Japan is scheduled to release the September 2026 Tankan Summary and Outline at 8:50 a.m. JST on Thursday, October 1. That is 5:20 a.m. IST. At the reference time—28 September 2026, 5:14 p.m. IST—the official quarterly results have not been released, so no September figures are confirmed.

Japan’s central bank last updated its release calendar on September 25. It places the Tankan beside, but separate from, the Summary of Opinions from the September 17–18 Monetary Policy Meeting, also due at 8:50 a.m. The calendar warns that issue dates can change without notice; a same-day check of the BOJ news list remains essential.

The timestamp converts to 11:50 p.m. UTC on Wednesday, September 30; 7:50 p.m. EDT in New York on September 30; 12:50 a.m. BST in London on October 1; and 1:50 a.m. CEST in central Europe on October 1. Japan is nine hours ahead of UTC and India is five and a half hours ahead, producing the three-hour, 30-minute difference between JST and IST.

The different calendar day in North America and UTC is not a separate release. It is the same scheduled publication moment. Readers should use 8:50 a.m. JST for the BOJ’s Tokyo timetable, then convert from that fixed point rather than from a generic Japan-time label.

What the Bank of Japan will publish

The October 1 package consists of the Tankan Summary and Tankan Outline. The Summary provides the headline tables most readers first encounter; the Outline supplies a more detailed presentation. Both are Bank of Japan statistical releases, not a speech or an interest-rate decision.

A further release matters for readers who need industry or cross-tab detail. The official calendar schedules the September Tankan Comprehensive Data Set for Friday, October 2, at 8:50 a.m. JST / 5:20 a.m. IST. It follows a day later and should not be described as part of the first-day release.

The simultaneous Summary of Opinions is a separate account of views expressed at the September monetary-policy meeting. It may add policy context, but it is not a Tankan result. Any report should label the two documents clearly and link each statement to its own source.

What the Tankan measures

Tankan is the Bank of Japan’s quarterly Short-Term Economic Survey of Enterprises in Japan. It records businesses’ assessments of current conditions and their expectations, alongside selected operational and financial plans. Its usefulness lies in the breadth of responses across enterprise sizes, manufacturing, non-manufacturing and individual industries.

Its headline business-conditions measure is a diffusion index, or DI. The BOJ calculates it as the share of respondents calling conditions favorable minus the share calling them unfavorable. A positive DI therefore signals a net favorable assessment; it is not a percentage growth rate, an output total or a forecast of national GDP.

The survey also publishes actual and three-month-ahead judgments. A movement in the outlook may be informative even when the current-condition index changes little. Users should compare like with like: the same enterprise size, sector, survey field and actual-versus-forecast column. The BOJ notes that its sample enterprises were most recently revised in March 2026.

A practical guide to reading the release

First, identify the current business-conditions DI for large manufacturers and the corresponding three-month forecast. Then do the same for large non-manufacturers and for the all-industries line. A headline that only reports one group can hide a split between factory activity and services.

Second, examine the fixed-investment plans, including the table’s stated treatment of land purchases, before treating investment as either broadly strong or weak. Read sales and profit plans, capacity conditions and employment conditions as separate survey fields rather than as interchangeable labels.

Third, look for the survey’s pricing and inflation-expectation measures, and for industry tables in the October 2 data set. Input and output price judgments, supply-and-demand assessments and inventory conditions can help explain business responses. They do not by themselves establish the cause of a change or the path of a commodity price.

The latest official baseline and independent context

The June 2026 survey is the latest completed official quarterly baseline. It reported a business-conditions DI of 22 for large manufacturers and 37 for large non-manufacturers. These numbers provide a dated reference point only; they are not a prediction for September and should not be presented as such.

Independent reporting provides pre-release context but not official results. Nippon.com and Jiji Press reported that the average forecast from 12 private think tanks put the large-manufacturer current-conditions DI at plus 26, four points above June. The report attributes the expectation partly to AI- and semiconductor-related demand. That consensus can be compared with the BOJ release after publication, but it must not be inserted as the September Tankan result.

Forecasts and official survey readings use different evidence and serve different purposes. A responsible results update should lead with the BOJ Summary and Outline, identify any comparison with a private consensus as such, and wait for the October 2 Comprehensive Data Set before making detailed industry comparisons.

Why the release is relevant to the BOJ policy backdrop

The Tankan arrives after the BOJ’s September 17–18 meeting, where the Policy Board voted 7–2 to guide the uncollateralized overnight call rate around 1.25%, effective September 24. In its statement, the Bank said the economy had recovered moderately, while noting risks including developments in the Middle East, AI-related demand and foreign exchange rates.

That background explains why the enterprise survey will be closely read, but it does not make the October 1 document a policy decision. The BOJ calendar lists its next Monetary Policy Meeting for October 29–30. One release cannot establish what the Board will do then, and this guide makes no claim about a future policy outcome.

What it can—and cannot—say about metals

For a metals and commodities audience, the release can provide evidence on the tone of Japanese manufacturers and on sector-level conditions once the detailed tables arrive. The June Summary, for example, carried separate industry lines for iron and steel, nonferrous metals, processed metals and machinery. The October report may differ; no September industry result is known in advance.

It is equally important to know the survey’s limits. Tankan is not a physical-demand series, an inventory count for a metal market, an import ledger or a commodity-price forecast. Any link from business sentiment to a particular material should remain conditional and be tested against relevant production, trade and supply data.

How this page should be updated after publication

At release time, this page should be updated from the Bank of Japan’s published Summary and Outline only. Add the actual current and outlook DIs for the relevant enterprise groups, the fixed-investment plans and any clearly identified pricing or inflation-expectation figures. Record the BOJ publication time and preserve the distinction between Tankan and the separate Summary of Opinions.

On October 2, add industry and size detail from the Comprehensive Data Set, with comparisons to June made on the same measure. If a number is revised, corrected or released later than scheduled, show the original source, the new timestamp and a concise correction note rather than silently overwriting the earlier account.

If the Bank changes the schedule before publication, the page should lead with the new official time and explain that the prior timetable was superseded. Until the documents are live, the accurate status is scheduled, not released. The post-release version should state facts from the tables and keep interpretation clearly separate from them.
