A Japan earnings calendar should answer three separate questions: when a Tokyo-listed company expects to report, which fiscal period the date belongs to, and where the actual release appears. The official sources are free, but no single page should be treated as a guaranteed appointment.
Start with Japan Exchange Group's scheduled earnings page, then verify the exact security code and fiscal year-end in Tokyo Stock Exchange Listed Company Search. On release day, confirm the document and timestamp in TDnet, the exchange's Timely Disclosure Network, or the JPX English Company Announcements Service. A company investor-relations calendar is a useful cross-check, not a substitute for the final filing.
The central caution is simple: a scheduled date is information supplied by the company and can change. A blank field does not prove that no release is coming, and a date alone does not tell you whether a label such as `Q1 FY2027` covers the calendar period you expect.
This guide uses JPX pages accessed on August 22, 2026.
Key takeaways
- Use the JPX scheduled-dates page for the market-wide view and Listed Company Search for the issue-specific check.
- Match the company name, four-digit TSE code and fiscal year-end before recording any date.
- Treat every date as provisional until the earnings document is actually posted.
- A blank schedule can mean the company has not registered a date yet, the page is outside its current display window, or the issuer follows a different fiscal calendar.
- The same calendar quarter can be `Q1` for a March-year-end company and `Q3` for a September-year-end company.
- Confirm the final release in TDnet or Company Announcements Service and preserve the Japan Standard Time timestamp.
- English coverage is strongest for domestic Prime Market companies, but the English item can still be later or less complete than the Japanese disclosure.
- Save the source URL and access time. The current Company Announcements service has a 31-day public window.
Start with the TSE calendar, but treat it as provisional
JPX maintains a Scheduled Dates for Earnings Announcements page using dates supplied by TSE-listed companies. It provides a useful market-wide starting point, especially during the concentrated reporting seasons after March, June, September and December quarter-ends.
The page has two important update patterns. For companies with fiscal years ending in March or September, JPX says the next-business-day announcement list is updated around 5:00 p.m. Japan Standard Time each business day. Broader company lists are posted after the relevant fiscal period ends and then updated as necessary.
That does not make the list complete or fixed. JPX explicitly warns that a company missing from the material can still report and that a company on the list can change its plan. The calendar therefore works as a discovery source, not as proof that an announcement will occur.

| What the TSE calendar shows | What it does not guarantee | Required next check |
|---|---|---|
| A company-supplied expected date | That the date will remain unchanged | Issue record and company IR page |
| A market-wide list for a covered period | That every reporting company appears | Search by exact company code |
| An expected reporting day | The final publication timestamp | TDnet or Company Announcements Service |
| A fiscal-quarter label | That the label matches the calendar quarter in your notes | Fiscal year-end and period-end date |
If a broker calendar, data vendor or search result disagrees with JPX, do not average the dates or choose the most convenient one. Record the discrepancy, open the exact issuer's TSE entry and check its own investor-relations calendar. The latest primary-source update should control the working calendar.
Verify the issue-specific record before release day
The TSE Listed Company Search guide explains what appears on an issuer record: security code, market segment, fiscal year-end and registered scheduled dates for first-, second- and third-quarter results. JPX says a scheduled date is provided the day after the listed company registers it.
This page is where two common international-investor errors can be caught. The first is an identity mismatch: a similarly named company, U.S. depositary receipt or overseas ordinary share may not be the Tokyo security you meant to track. The second is a fiscal-calendar mismatch: a September-, December- or February-year-end company will not use the same quarter label as a March-year-end peer.
JPX also notes two display limits. A scheduled full-year earnings date is not shown until the window beginning 20 business days before the company's fiscal year-end. Companies that change their accounting period can display dates irregularly. In other words, a blank full-year field well before year-end is not a missing-results signal.
Use this issue-level sequence:
1. Confirm the exact company name and four-digit TSE code. 2. Confirm the market segment and fiscal year-end. 3. Record the scheduled quarter date and the page access time. 4. Cross-check the issuer's investor-relations calendar or financial-results page. 5. Recheck both sources on the prior business day and again on the scheduled date.
The ATG Press guide to Japanese stock tickers and ADRs gives a fuller code-matching workflow. It is worth completing that step before building a multi-company earnings calendar.
Translate the fiscal label before comparing companies
Japanese results are usually labeled by the fiscal year in which the accounting period ends. For a company whose year ends on March 31, the three months ending June 30 are the first quarter of the fiscal year ending the following March. The release can therefore contain a fiscal-year number that is one higher than the calendar year in which the quarter began.
A September-year-end company can call the same June 30 period its third quarter. A December-year-end company can call it its second quarter. The economic period is identical; the fiscal position is not.

| Company fiscal year-end | Period ending June 30 | Common fiscal label | What to store in a research log |
|---|---|---|---|
| March 31 | Three months ended June 30 | Q1 of the fiscal year ending the following March | Period end, quarter number and full-year end |
| September 30 | Nine months ended June 30 | Q3 of the fiscal year ending that September | Period end, quarter number and full-year end |
| December 31 | Six months ended June 30 | Q2 of the fiscal year ending that December | Period end, quarter number and full-year end |
| Nonstandard or changed year-end | Depends on the transition term | Can be irregular | Exact start date, end date and number of months |
Do not compare `Q1` growth rates across companies until the start and end dates match. Also separate completed-period results from management's forecast for the full year. ATG Press's Japanese earnings-report guide explains how to distinguish the reported result, company guidance, accounting standard and dividend forecast after the document appears.
Confirm the actual release in TDnet
TDnet is the TSE system used for timely disclosure. JPX's overview of TDnet says disclosure documents are posted when released, together with the date and time, company code, name and title. That timestamp—not the calendar entry—is the evidence that the results became public.
For English research, the JPX Company Announcements Service provides English materials submitted through TDnet. Since April 2025, domestic Prime Market companies have been required to disclose financial results and timely information simultaneously in Japanese and English. An English excerpt or summary can satisfy that rule, so the English file may contain less detail than the Japanese original.
JPX also warns that English information can appear later than Japanese and may not cover every Japanese disclosure. If the expected English item is absent, check the Japanese Company Announcements Disclosure Service and the issuer's own results page before concluding that the company did not report.
The current public announcement window is 31 days, including weekends and national holidays. For older timely disclosures, use Listed Company Search; for annual securities reports and other statutory filings, use EDINET. The ATG Press TDnet guide covers the released-document search, while the EDINET guide explains the separate statutory archive.

Build a Japan earnings calendar that survives changes
A durable earnings calendar needs more than one date column. Preserve the instrument identity, fiscal period, source and verification state so that a changed schedule does not silently overwrite the original plan.
Use at least these fields:
- company name and four-digit TSE code;
- market segment and fiscal year-end;
- accounting period start and end dates;
- fiscal label shown by the issuer;
- expected release date in Japan Standard Time;
- source URL and access timestamp;
- prior expected date, if changed;
- actual TDnet publication timestamp;
- English-document status: full, summary, delayed or unavailable;
- next review time and the person or system responsible.
When tracking several companies, sort by expected date only after normalizing the time zone. Japan does not observe daylight saving time. A release logged as 3:00 p.m. JST is 6:00 a.m. UTC throughout the year, although the local time in New York or London changes when those regions enter or leave daylight saving time.
Avoid inserting a precise time when the official source provides only a date. Many company calendars announce the day but not the minute. Record `time not disclosed` and replace it with the TDnet timestamp after publication.
Release-day checklist
On the expected reporting day:
1. Reopen the issue's Listed Company Search record and company IR calendar. 2. Confirm the four-digit code, fiscal year-end and expected period. 3. Search TDnet or Company Announcements Service by code, not only by company name. 4. Compare the document title with the expected quarter and accounting period. 5. Record the actual Japan Standard Time publication timestamp. 6. Check whether the English item is a full report, excerpt, summary, update or delayed release. 7. Save the source URL and retrieve the file before the 31-day window closes. 8. Separate reported results, revised guidance and dividend changes in your notes. 9. If no item appears, check the Japanese service and issuer site before marking the release missed. 10. Update the next scheduled period from a primary source rather than extrapolating three months mechanically.
The practical rule is to treat the calendar as a queue of expected events and TDnet as the confirmation layer. Match the instrument and fiscal year first, keep the expected date provisional, and replace it with the actual filing timestamp only when the document is public.
