Japan listed financial groups investable universe

Wiki route

This page sits under finance index. It is a public-source reference universe for Japan-listed financial groups, read against japan-ib-league-table for adviser-side peer mapping, japan-activist-investor-playbook for engagement / control reading, japan-large-shareholding-disclosure for stake disclosure mechanics, japan-shareholder-proposal-and-agm-voting-route for AGM / stewardship route, and finance INDEX for entity-level pages. System-side context lives at tokyo-stock-exchange and japan-market-infrastructure-map.

TL;DR

This is a reference universe map of Japan-listed financial groups, organised by sub-sector. It is NOT a buy / sell list, NOT investment advice, NOT a recommendation, and NOT a model portfolio. Company names, codes, and listing status are an editorial snapshot checked against the June 2026 month-end file published on JPX’s monthly listed-company data page. This is a month-end / list-publication context, not a daily as-of claim. Business perimeter, ownership, index membership, and financial metrics must be established separately from dated issuer, JPX, EDINET, or index-provider records.

Universe Scope

Source: coverage is an editorial taxonomy checked against the June 2026 month-end file on JPX’s monthly listed-company data page; it is representative rather than exhaustive and does not establish investability for any reader.

The universe is read against finance INDEX, which is the entity-level index for individual issuers.

Universe Matrix Fields

Source: the June 2026 month-end file on JPX’s monthly listed-company data page is the control used here for issuer name, code, and listing status in that month-end / list-publication context. The tables intentionally omit market capitalisation, ROE, yield, foreign ownership, index membership, capital-return policy, and risk rankings because those fields require a named observation date and primary evidence.

Megabank FGs

Source: entity names, codes, and listing status were checked against the June 2026 month-end file on JPX’s monthly listed-company data page. Category labels are navigation aids, not current financial or investment conclusions.

Read these against japan-ib-league-table for adviser-side franchise depth and finance INDEX for entity-level pages.

Trust FG

Source: the entity name, code, and listing status were checked against the June 2026 month-end file on JPX’s monthly listed-company data page.

Regional FGs (representative)

This list is representative, not exhaustive. Names, codes, and listing status were checked against the June 2026 month-end file on JPX’s monthly listed-company data page; geography is an editorial navigation label that should be confirmed from the issuer profile.

For any engagement analysis, first establish the current holder, proposal, voting record, and issuer response through the routes in japan-activist-investor-playbook.

Net banks / digital banks and bank-adjacent listed names

Source: entity names, codes, and listing status were checked against the June 2026 month-end file on JPX’s monthly listed-company data page. Rakuten Group’s ownership figure is taken from its February 25, 2026 disclosure.

SBI Sumishin Net Bank (code 7163) is excluded from this listed-company snapshot because JPX recorded its September 25, 2025 delisting. Establish any later parent or business-perimeter statement from a current issuer filing rather than from the former listing.

Major insurers (listed)

Source: names, codes, and listing status were checked against the June 2026 month-end file on JPX’s monthly listed-company data page. Insurance-business labels are editorial navigation categories.

Life insurers are read with japan-large-shareholding-disclosure when the cross-holding unwind shows up on the disclosure surface.

Major securities

Source: names, codes, and listing status were checked against the June 2026 month-end file on JPX’s monthly listed-company data page. The category is a research-routing label; current segment composition belongs to the issuer’s dated filings.

Read these with japan-ib-league-table for advisory franchise depth; megabank-affiliated securities arms (SMBC Nikko, Mizuho Securities, MUFG / MUMS) sit inside parent FG entries above and inside finance INDEX.

Card / consumer finance

Source: names, codes, and listing status were checked against the June 2026 month-end file on JPX’s monthly listed-company data page. Pocket Card is excluded because JPX records its February 1, 2018 delisting. Acom’s ownership figure is taken from its issuer stock-information page, dated March 31, 2026.

For risk analysis, use each issuer’s latest securities report and financial disclosures; the category label does not establish a current risk ranking.

Leasing

Source: names, codes, and listing status were checked against the June 2026 month-end file on JPX’s monthly listed-company data page. The category is an editorial routing label.

Unlisted peers are outside this universe; verify their ownership and business perimeter separately from current issuer records.

Telco-finance / payment hybrid

Source: names, codes, and listing status were checked against the June 2026 month-end file on JPX’s monthly listed-company data page. SoftBank Group is the group shorthand; the direct holder identified on SoftBank Corp’s issuer stock-information page, dated March 31, 2026, is SoftBank Group Japan Corporation.

These hybrid entries are useful to read alongside finance INDEX because the financial subsidiary balance sheets are disclosed inside the telco parent.

Fintech / crypto

Source: names, codes, and listing status were checked against the June 2026 month-end file on JPX’s monthly listed-company data page. Business mix must be checked against each issuer’s latest securities report.

Monex appears in both the “Securities” matrix and here, because the fintech sub-sector intersects with the listed-securities sub-sector.

Index Inclusion Layer

Source: this table provides verification routes, not constituent claims. Use JPX TOPIX materials, the Nikkei Indexes constituent data, and the relevant FTSE Russell constituent file current on the decision date.

Index inclusion rotates; always re-confirm against tokyo-stock-exchange and the JPX TOPIX methodology page before relying on a name’s index status.

Stewardship / Engagement Anchor Layer

The engagement route is documented in japan-shareholder-proposal-and-agm-voting-route and japan-activist-investor-playbook. The following are research questions, not claims that any named issuer is currently subject to a campaign:

• cost of capital, PBR < 1.0 pressure, and capital-policy disclosure (TSE cost-of-capital request);
• cross-holding (政策保有株) unwind pace and disclosure;
• payout ratio, buyback policy, and total shareholder return policy;
• board independence, nomination, compensation, and skill matrix;
• conglomerate discount and segment disclosure (for SBI HD, ORIX, KDDI, SoftBank Corp, Mercari);
• governance event response (Mizuho FG system events, Sompo HD agency-channel governance events, regional FG-specific events).

Cross-holding unwind for insurers and megabanks shows up on the japan-large-shareholding-disclosure surface when blocks move; activist or strategic positions in regional FGs and consumer finance issuers also surface there.

Capital-Action Layer

Recent capital actions across this universe (presence-only descriptor; verify before use):

Source: this is an evidence-requirement table. Establish any issuer-specific action through JPX TDnet, EDINET, and the issuer’s dated filing; the table makes no current issuer-level assertion.

For any specific capital action, the primary record is the issuer’s TDnet release, EDINET securities report or extraordinary report, and the issuer IR page. None of the above is investment advice.

Risk-Diligence Questions by Sub-Sector

Source: the table is an analytical diligence-question taxonomy—not issuer facts—derived from the public filing routes described above. Validate materiality and direction from each issuer’s current financial, regulatory, and risk disclosures.

Reader Verification Checklist

Before using any line in this page in any real-world decision, the reader should:

1. Open the issuer’s TDnet recent-disclosure feed via JPX TDnet.
2. Pull the most recent securities report and extraordinary reports from EDINET.
3. Cross-check index inclusion (Nikkei 225 / TOPIX / TOPIX Core 30 / FTSE Russell) against the JPX TOPIX methodology page and the relevant index provider.
4. Re-confirm the latest kessan tanshin and IR deck on the issuer’s IR page.
5. For stewardship / engagement reading, cross-reference japan-shareholder-proposal-and-agm-voting-route and japan-activist-investor-playbook.
6. For large-shareholding stakes, pull the EDINET 大量保有報告書 / 変更報告書 stack per japan-large-shareholding-disclosure.
7. Date-stamp the verification step in the reader’s own notes; this page’s matrix descriptors are public-surface-only and will go stale.

Caveats

• This is a public-surface reference universe page, not a model portfolio, not a recommendation, not investment advice, not tax advice, not legal advice.
• Names, codes, listing status, and editorial categories can change through mergers, TOBs, reorganisations, and corporate actions; this page records the June 2026 month-end / list-publication context from JPX’s monthly-data page.
• This page deliberately omits ROE, dividend yield, foreign ownership, capital-policy rankings, and constituent assertions. Retrieve them from dated primary or licensed sources.
• Index inclusion rotates periodically; the current index-provider constituent record controls.
• Some financial businesses sit inside listed parents rather than as standalone listings. Establish the current parent perimeter from dated issuer filings.
• Private financial groups (e.g. JA Mitsui Leasing, mutual life insurers) are explicitly out of scope for an “investable universe” page because they are not listed.
• Data verification is the reader’s responsibility. The FinWiki public-surface convention is route-and-link, NOT signal generation.
