# Japan cross-shareholding unwinding economics

## Wiki route

This page sits under [[finance/INDEX|finance domain]]. Read it with [[finance/japan-listed-financial-groups-investable-universe|listed financial groups investable universe]] for the bank / insurer issuer side, [[finance/japan-activist-investor-playbook|Japan activist investor playbook]] for the activist-pressure interface, [[finance/japan-fair-disclosure-and-insider-trading-controls|fair disclosure controls]] for the disposal-timing information handling, [[finance/japan-convertible-bond-mechanics|convertible bond mechanics]] for exchangeable-bond monetisation, and [[finance/japan-large-shareholding-disclosure|large shareholding disclosure]] for ownership-change reporting.

## TL;DR

Japan cross-shareholding (政策保有株, *seisaku hoyū kabushiki*, or "policy holding stock") refers to listed companies holding shares for purposes other than pure investment, including stated business relationships. Corporate Governance Code revisions from 2015 through the [July 2026 revision](https://www.jpx.co.jp/english/corporate/news/news-releases/1020/20260721-01.html), together with securities-report disclosure rules, require current issuer-specific reading. Under IFRS 9, an issuer may irrevocably designate an eligible equity investment at FVOCI and does not recycle the cumulative disposal gain or loss to P&L. Japanese GAAP is different: marketable "other securities" are fair-valued through net assets / OCI, but disposal gains and losses are recognised in current P&L. Disposal routes can include market sales, ToSTNeT transactions, issuer buybacks, and exchangeable-bond structures; their tax, accounting, capital, and disclosure outcomes are transaction-specific.

## What counts as policy-holding stock

Source: the table follows [JPX's current Corporate Governance Code route](https://www.jpx.co.jp/english/equities/listing/cg/index.html) and the FSA's [FY2026 securities-report disclosure review](https://www.fsa.go.jp/news/r7/sonota/20260327.html); issuer classification and holding-by-holding rationale must be read from the issuer's current securities and corporate-governance reports.

| Field | Detail |
|---|---|
| Definition | Equity classified by the issuer as held for a purpose other than pure investment; the stated purpose and current filing control |
| Corporate Governance Code | The issuer discloses its policy and examination of individual cross-shareholdings under the Code principles applicable to its market and reporting date |
| Securities Report | Holding-specific fields, purpose, and any required explanation of a change to pure-investment classification follow the current Cabinet Office Ordinance and FSA review guidance |
| Counter-holding | Mutual holding (相互持合い, *sōgo mochiai*) where both companies hold each other's shares |
| Voting | Voting behaviour must be established from the holder's disclosed policy or vote record; the holding label alone does not establish support for management |

Classification is purpose-based. A stake may be reclassified between pure investment (純投資, *jun-tōshi*) and policy holding, but the applicable securities-report fields—not a generic "CG-code event" label—determine what explanation is required. The FSA's FY2026 review materials require concrete purposes and, for a change to pure-investment classification, disclosure of the reason and the post-change holding or sale policy.

## Regulatory pressure trajectory

Source: the table is a high-level chronology keyed to the FSA's [Corporate Governance Code materials](https://www.fsa.go.jp/en/refer/councils/corporategovernance/index.html) and [JPX current Corporate Governance Code](https://www.jpx.co.jp/english/equities/listing/cg/index.html); it does not substitute for the version in force on an issuer's reporting date.

| Year | Development |
|---|---|
| 2014 | Stewardship Code introduced |
| 2015 | First CG Code, including policy-holding stock disclosure principles |
| 2018 | CG Code revision tightened policy-holding disclosure and board-review obligations |
| 2021 | CG Code revision pushed Prime-listed companies toward more rigorous review |
| 2023-2025 | FSA and JPX published governance action and capital-cost materials relevant to issuer review and disclosure |
| 2026 | JPX published the July 2026 Corporate Governance Code revision; FSA continued securities-report review of policy-holding disclosures |
| Reporting-date specific | Apply the Code, securities-report rules, and issuer policy in force for the relevant filing |

The CG Code operates on a "comply or explain" basis. For issuers to which the relevant Code items apply, confirm the disclosed policy, board verification, and explanation required by those items. Separately identify the statutory securities-report fields applicable to the issuer and reporting period; do not treat Code explanations and statutory fields as the same obligation.

### IFRS 9 (for issuers applying IFRS)

| Field | Treatment |
|---|---|
| Classification | Equity instruments default to FV-PL unless irrevocably designated at FV-OCI at initial recognition |
| FV-OCI election | An eligible equity investment may be irrevocably designated at FVOCI at initial recognition; verify the issuer's accounting policy |
| Dividend | Recognised in P&L |
| Fair-value changes | Recognised in OCI (other comprehensive income) |
| Disposal | No recycling to P&L; cumulative gain / loss transferred within equity only |
| Impairment | Not applicable under FV-OCI for equity (no impairment test required, but fair value reflects market) |

The non-recycling rule means disposal does not produce a P&L gain. This is the critical accounting-incentive change vs the legacy IAS 39 available-for-sale model where realised gain went to P&L.

### Japanese GAAP (other securities)

Japanese GAAP does not replicate IFRS 9's equity-FVOCI non-recycling outcome. Under ASBJ's accounting standard and implementation guidance for financial instruments, marketable "other securities" are measured at fair value with the valuation difference recorded in net assets / OCI under the selected method, while a disposal gain or loss is recognised in current P&L.

Source: every row in the table is tied to the ASBJ's [Accounting Standard for Financial Instruments and related implementation guidance](https://www.asb-j.jp/jp/accounting_standards_system/details.html?topics_id=109); issuer elections and the standard effective for the reporting period must be checked in its accounting policies.

| Field | Treatment under Japanese GAAP |
|---|---|
| Marketable other securities | Fair value on the balance sheet |
| Dividend | P&L |
| Fair-value changes | Valuation difference recorded in net assets / OCI under the selected method |
| Disposal gain / loss | Recognised in current P&L; the related valuation difference is reversed / washed out |
| Equity without a quoted market price | Cost subject to the applicable impairment and measurement guidance |

Do not infer the IFRS 9 no-recycling result from a Japanese-GAAP issuer's use of OCI presentation.

## Disposal-route diligence

Source: the table is a route-level diligence map using JPX's [ToSTNeT market description](https://www.jpx.co.jp/english/equities/trading/tostnet/index.html). For every tax field, identify the taxpayer, status, and transaction, then verify the current corporate-tax treatment against the exact NTA guidance or statute that applies; this table does not state a tax outcome.

| Route | Mechanics | Tax / execution question |
|---|---|---|
| Open-market sale | Sell through exchange | Identify the taxpayer, status, basis, and transaction, then verify the treatment under current corporate-tax rules against exact NTA guidance or statute |
| ToSTNeT transaction | Use the applicable JPX off-auction facility | Confirm execution method, price, size, and disclosure; perform the same exact-rule corporate-tax verification, and do not predetermine market impact |
| Share buyback by issuer | Issuer repurchases its own shares from the holder | Verify the taxpayer, status, transaction, and current corporate-tax rules against exact NTA guidance or statute; do not infer deemed-dividend or disposal treatment from the route label |
| Exchangeable bond | Bond terms may reference or be exchangeable into the holding — see [[finance/japan-convertible-bond-mechanics|convertible bond mechanics]] | Establish issuer, settlement, exchange, disposal, accounting, and tax timing from the instrument terms |
| Spin-off / partial spinoff | Distribute holding shares to own shareholders | Test the actual structure against the current statutory qualification rules — see [[corporate-strategy/japan-kabushiki-bunpai-spinoff-regime|partial spinoff tax deferral]] |
| In-kind dividend | Distribute holding shares to own shareholders | Determine the classification and corporate-tax treatment from the actual structure and exact current rule |
| Cross-trade | Counter-holders execute coordinated disposals if legally and operationally available | Analyse each leg, price formation, disclosure, and tax independently |
| Auction / secondary equity offering | Place shares through a documented sale or offering process | Confirm the chosen process, offering documents, fees, allocation, and tax from the actual transaction |

Do not infer a deemed-dividend component, disposal treatment, or dividends-received exclusion from an issuer-buyback label. Identify the taxpayer, status, basis, consideration, and transaction, and verify each result under the exact current corporate-tax statute and NTA guidance.

## Strategic signal in unwinding

Source: this table is an analytical interpretation checklist informed by the FSA's [2025 corporate-governance action programme](https://www.fsa.go.jp/en/news/2025/20250630-1.html) and [JPX current Corporate Governance Code](https://www.jpx.co.jp/english/equities/listing/cg/index.html). It does not assert that a trend or effect exists; verify each observation and interpretation in current issuer filings.

| Signal | Interpretation |
|---|---|
| Issuer reports a faster reduction pace | What period, denominator, target, realised sale, and capital effect does the filing quantify? |
| Issuer retains selected holdings | What concrete business purpose and board examination does the filing disclose for each holding? |
| Bank or insurer disposes of equities | Does the regulatory filing quantify any CET1, risk-weighted-asset, solvency, or ALM effect? |
| Counter-holders act at different times | Do both issuers' filings explain the decisions, or would a relationship inference be speculative? |
| Investor requests disposal or capital return | What exactly does the investor's public proposal request, and how does the issuer respond? |
| Classification or rationale changes | What reason, post-change policy, and reporting-rule field does the current filing provide? |

Do not assume disposal proceeds are returned to shareholders. Record a buyback, dividend change, debt reduction, reinvestment, or other use only when the issuer's dated disclosure links it to the disposal or capital-allocation plan.

## Peer comparison framework

The right comparison uses publicly disclosed Securities Report holdings and CG-report disclosures.

### Megabanks

| Group | Public disclosure source |
|---|---|
| [[megabanks/mufg|MUFG]] | MUFG annual securities report and integrated report; CG report on TSE |
| [[megabanks/smfg|SMFG]] | SMFG annual securities report and integrated report; CG report on TSE |
| [[megabanks/mizuho-fg|Mizuho FG]] | Mizuho FG annual securities report and integrated report; CG report on TSE |

For each megabank, extract any reduction target, denominator, baseline date, horizon, and progress from its current securities or integrated report. Do not apply one group's CET1, book-value, or fair-value presentation to another.

### Shōsha

| Group | Holding profile |
|---|---|
| [[financial-conglomerates/mitsubishi-corp|Mitsubishi Corp]] | Cross-holdings include group / partner equity, with public disclosure of major positions |
| [[financial-conglomerates/mitsui-co|Mitsui & Co]] | Public disclosure of policy-holdings and rationale |
| [[financial-conglomerates/itochu-corp|Itochu Corp]] | Current securities report, integrated report, and holding-specific rationale |

For each shōsha, use the issuer's classification and stated purpose for a holding; do not infer a supply-chain role or disposal priority from sector labels alone.

### Insurers

For each life or non-life insurer, read the current securities report, integrated report, solvency disclosure, and accounting policy. Quantify a disposal programme or solvency / ALM effect only when that issuer discloses it; IFRS 9 and Japanese GAAP are not interchangeable.

### Manufacturing and trading partners

Industrial-company holdings must be classified from the issuer's filing. Supplier, customer, group-company, sector, and disposal conclusions require holding-specific evidence rather than a sector-wide assumption.

## Disclosure surfaces

Source: the table routes to [EDINET](https://disclosure2.edinet-fsa.go.jp/), [JPX TDnet](https://www.jpx.co.jp/english/equities/listing/disclosure/tdnet/index.html), and the FSA's [large-shareholding filing route](https://www.fsa.go.jp/common/shinsei/tairyohoyu/index.html); document availability and filing triggers are source-specific.

| Surface | Document |
|---|---|
| Securities Report (有価証券報告書) | Annual statutory filing; holding-specific fields and rationale where required by the current disclosure rules |
| CG Report (コーポレートガバナンス報告書) | Periodic CG-code compliance report on TSE; policy on policy-holdings |
| Integrated Report | Voluntary narrative; use only the policy-holding detail actually published by the issuer |
| TDnet | A disposal or acquisition appears only if the listed-company disclosure rules or the issuer's decision make a timely disclosure applicable |
| EDINET large shareholding reports | A holder already within the reporting regime files a change report when a statutory reportable change occurs; crossing below 5% is not the sole test (see [[finance/japan-large-shareholding-disclosure|large shareholding disclosure]]) |
| AGM convocation notice | Voting-policy detail for policy-holdings; can become activist-proposal item (see [[finance/japan-shareholder-proposal-and-agm-voting-route|shareholder proposal route]]) |

## Activist interface

Public investor proposals may address cross-shareholding as a capital-efficiency issue. Possible requests, which must be verified from the actual proposal, include:

- Disposal of policy-holdings and return of proceeds via buyback / dividend.
- Board-level review enhancement and disclosure rigour.
- Independent committee oversight of policy-holding policy.
- Counter-holder reciprocal disposal.

See [[finance/japan-activist-investor-playbook|activist playbook]] for the demand-and-response routing.

## Disposal information control

A planned disposal may be material or constitute non-public information depending on the issuer, holder, size, and facts. Apply the FIEA insider-trading rules, fair-disclosure framework, confidentiality obligations, and issuer controls to the actual information. See [[finance/japan-fair-disclosure-and-insider-trading-controls|Japan fair disclosure and insider trading controls]].

| Issue | Control point |
|---|---|
| Information access | Determine whether restricted lists, access controls, confidentiality agreements, or other measures are appropriate |
| Arranger selection | Record an arranger only from the mandate or transaction disclosure; a [[finance/japan-ib-league-table|league table]] does not prove the role |
| Pricing process | Identify the executed market, negotiated, auction, offering, or other process without assuming its price effect |
| Timing relative to issuer information | Apply the relevant trading restriction, disclosure, and confidentiality analysis |
| Counterparty engagement | Record consultation or reciprocal action only when a public document supports it |

## Capital and CG-code implications

Policy-holding stock affects regulatory capital and capital-efficiency ratios:

Source: the table is an analytical effect map grounded in the FSA's [2025 corporate-governance action programme](https://www.fsa.go.jp/en/news/2025/20250630-1.html) and [JPX's 2026 capital-cost update](https://www.jpx.co.jp/english/news/1020/20260428-01.html); each effect is conditional and must be quantified from the issuer's regulatory and financial disclosures.

| Metric | Effect of disposal |
|---|---|
| Megabank CET1 / risk-weighted assets | Direction and magnitude depend on regulatory treatment, sale gain or loss, deductions, taxes, and use of proceeds |
| Insurer solvency measure | Direction and magnitude depend on the applicable solvency regime, asset-risk charge, taxes, and use of proceeds |
| Corporate ROE | Effect depends on sale gain or loss, tax, retained earnings, and whether proceeds change the equity base or earnings |
| Capital allocation | The issuer must disclose the actual use of proceeds and decision; disposal alone does not establish discipline |
| TSE capital-cost / share-price initiative | A disposal may form part of an issuer's plan, but TSE does not prescribe disposal or shareholder return as the required response |

## TSE PBR-1x initiative

TSE requested all Prime and Standard Market companies to explain management that is conscious of capital cost and share price; it is not a standalone PBR-at-least-1x listing requirement. Cross-shareholding disposal can be one issuer-selected lever alongside buybacks, dividend changes, and asset disposals.
