For Japanese stocks, the most useful starting point is not a generic board score. It is the Tokyo Stock Exchange (TSE) corporate-governance record: first confirm whether a director is designated as independent, then read the company’s Corporate Governance Report and its update date. TSE describes an independent director or auditor as an outside director or auditor unlikely to have a conflict of interest with general shareholders. That is a useful screening fact, but it is not proof that a board will make good decisions.
Key takeaways
- TSE requires listed companies to secure at least one independent director or auditor, and the designation is recorded in an official notification.
- “Outside” and “independent” should not be used as synonyms. The independent designation is the additional conflict-of-interest test that matters for the TSE notification.
- Use the company code or name in TSE's Listed Company Search, then check the Corporate Governance Report, the independent-director notification and the report’s last-update date.
- In TSE’s July 2026 aggregation, 98.8% of Prime Market companies had at least one-third independent directors, but only 29.9% had a majority. Counts are a starting point, not a governance conclusion.
What “independent” means in TSE reporting
TSE’s listing framework requires a listed company to secure at least one independent director or auditor for the protection of general shareholders. Its definition is specific: the person is an outside director or auditor who is unlikely to have a conflict of interest with general shareholders. Companies submit an Independent Directors/Auditors Notification to confirm compliance, and TSE makes that notification available through its Listed Company Search.
That makes two questions worth separating. First, is the person classified as an outside director? Second, has the company designated that person as independent for TSE purposes? A company can disclose both in its governance materials, but the labels answer different questions. Do not infer a person’s judgment, voting record or expertise from either label alone.
For context, TSE says corporate-governance reports exist to give investors a more comparable place to review governance information rather than leaving it scattered through financial statements. That makes the report more useful than a board count copied into a screening tool: it can show the company’s stated governance policy, structure and explanations.
Find the Japan independent directors report in three steps
Start at TSE’s Listed Company Search and search by the company’s name or four-digit TSE code. Open the company record, then locate both the Corporate Governance Report and the independent-director notification. The report is the broader source; the notification is the direct designation record.
Next, use TSE’s Corporate Governance Information Search when you need a screen rather than a single-company check. The exchange says this service can filter by market division, business sector, organizational structure, parent-company status, numbers of outside and independent directors or auditors, and date of update. It also offers a filter for companies with Corporate Governance Reports in English.
Finally, record the report date. TSE’s July 2026 preparation guidelines say the “last update” is the date the report was submitted to the exchange — the date it was registered on the Timely Disclosure network (TDnet), TSE’s electronic disclosure system. A report date is not a guarantee that every linked investor-relations document is current, but it tells you which version you are reading.
Read the count as a baseline, not a verdict
TSE’s latest survey was published on 21 July 2026 and is based on Corporate Governance Reports as of 14 July 2026. The figures show a clear difference between a one-third threshold and a majority threshold, especially outside the Prime Market.

| TSE market segment | Companies in survey | Two or more independent directors | One-third or more independent directors | Majority independent directors | Source / data cut-off |
|---|---|---|---|---|---|
| Prime Market | 1,551 | 1,546 (99.7%) | 1,532 (98.8%) | 463 (29.9%) | TSE survey; 2026-07-14 |
| Standard Market | 1,563 | 1,352 (86.5%) | 974 (62.3%) | 117 (7.5%) | TSE survey; 2026-07-14 |
| Growth Market | 594 | 446 (75.1%) | 406 (68.4%) | 106 (17.8%) | TSE survey; 2026-07-14 |
| All surveyed companies | 3,708 | 3,344 (90.2%) | 2,912 (78.5%) | 686 (18.5%) | TSE survey; 2026-07-14 |
The survey is a market baseline, not a ranking. A majority-independent board does not automatically make a company better run, and a smaller number does not settle the question in the other direction. Read the count alongside the board’s role, committee composition, skills, major-shareholder context and the company’s own explanations.
The distinction is useful when studying the broader Japanese governance record. ATG Press’s guide to Japan’s Governance Code and growth investment explains why board oversight is also tied to strategy and capital allocation, while the cross-shareholdings guide shows a separate ownership question that a director count cannot answer.
What to check inside the Corporate Governance Report
The official report format gives a practical reading order. TSE’s Corporate Governance Information Search says its records can include the company’s basic governance policy, capital structure, director and auditor appointments, management structure, shareholder and stakeholder measures, and internal-control information. Use the first pass to establish facts; use the second pass to test whether the explanation is specific.

| Check | What to look for | Why it helps | Limitation |
|---|---|---|---|
| Independent-director notification | Which outside directors or auditors are designated as independent | Confirms the TSE designation rather than relying on a third-party label | Does not measure board effectiveness |
| Corporate Governance Report update date | The date registered with TSE | Identifies the report version and whether an older narrative needs checking | It is not a real-time governance score |
| Board and committee structure | Number and role of outside and independent members; nomination and remuneration arrangements | Shows where oversight is formally placed | Formal structure does not show meeting quality or dissent |
| Ownership and capital structure | Parent-company status, major shareholders and cross-shareholding disclosures | Provides context for potential influence and incentives | Requires reading the underlying disclosures, not just a filter result |
| Company explanation | Specific policy, rationale and links to evidence | Lets a reader distinguish a concrete disclosure from boilerplate | Company language is management’s account, not independent verification |
TSE’s current report guidelines also give readers an important timing caution. During the transition to the July 2026 Corporate Governance Code, companies may update disclosures based on the June 2021 version until 31 July 2027, provided they state that basis and subsequently update. When comparing companies, note the report date and the Code version rather than assuming that every document uses an identical template.
Use English availability carefully
TSE provides an English-report filter, and its Corporate Governance Report page explains how to use it. That is a valuable route for international readers, but it is not a completeness guarantee. TSE explicitly notes on the governance-information search page that some information can only be displayed in Japanese.
Where the English report is unavailable or unclear, treat the English-availability result as a navigation aid, not as a conclusion about disclosure quality. Check the company’s investor-relations site and the underlying TSE record. For broader document discovery, ATG Press’s TDnet English guide explains how to locate Japanese company filings and identify the original source.
A practical Japan independent directors checklist
- Search the company by name or TSE code and save the Corporate Governance Report and independent-director notification.
- Record the market segment, the report’s last-update date and whether an English version is available.
- Separate the number of outside directors from the number designated independent.
- Read the board and committee descriptions before comparing the count with a market baseline.
- Check capital structure, major shareholders and cross-shareholdings alongside the board data.
- Revisit the record after annual general-meeting changes, governance-report updates or material corporate actions.
This workflow does not predict a stock’s performance. It helps an investor verify which governance facts are disclosed, where they came from and what further questions the facts cannot answer.
