Japan prime brokerage and institutional financing matrix

TL;DR

Prime brokerage in Japan is not a single license — it is a wholesale-service stack assembled from a Type I 金商業者 license, stock-borrow / loan capability, margin and repo financing, OTC and listed-derivatives capability, custody / settlement infrastructure, capital-introduction services, and (in many cases) global cross-border integration with the provider’s London / New York books. This matrix compares the ten material PB / institutional-financing providers operating in Tokyo today — Nomura, Daiwa SG, SMBC Nikko, Mizuho Securities, SBI Securities, Goldman Sachs Japan, Morgan Stanley MUFG (MUMSS), JPMorgan Japan, Citi Japan, Bank of America Japan — across client-mix tilt, product depth, collateral haircut policy, stock-borrow capability, settlement footprint, capital introduction, and geographic / cross-border integration.

Wiki route

This page sits under securities index as the provider-comparison matrix companion to Japan prime brokerage and institutional financing (the conceptual / functional overview). Read it with Japan stock lending market route for the stock-borrow rail, Japan margin trading and securities finance for the retail-margin distinction, Japan market infrastructure map for the JSCC / JASDEC settlement rail, Japan best execution / SOR / PTS for the execution-venue layer, and Japan PTS liquidity data guide for PTS-side liquidity flow. The legal-stack anchor is securities license stack, and segment-level classification is in Japan FIEA operator registry segment matrix.

Why this matrix matters

A blanket reference to “prime broker in Tokyo” hides the structural differences that drive PB selection economics:

• which client mix the provider’s PB book is built around (hedge funds vs family offices vs registered AMs vs sovereign / pension);
• which products and balance-sheet capacity the provider can extend (stock loan availability, repo capacity, OTC derivatives, FX prime);
• which collateral haircut grid and margin model the provider runs;
• whether the provider runs cross-border integration with London / NY (24-hour book; global stock-borrow inventory);
• which settlement infrastructure the provider clears through (JSCC direct vs sub-clearing, JASDEC direct member vs custodian-routed);
• whether the provider offers capital introduction (capintro) — the soft-dollar service that drives PB selection for newly launching hedge funds.

Without provider-level decomposition, a $50m macro hedge fund launching in Tokyo, a $5bn long-short equity fund, a family office, and a sovereign-wealth fund all look like “PB clients” — but their provider shortlists barely overlap.

Provider 1 — Nomura (Prime Finance — Nomura Securities)

• License footprint. Type I 金商業者 (Nomura Securities Co., Ltd.); JSDA full member; PTS-eligible underlying broker; JIPF-covered customer-asset segregation. Bank-affiliated trust services through MUTB-equivalent custodian arrangements within Nomura group.
• PB client mix. Heaviest domestic-hedge-fund coverage of any provider — long-only AMs, domestic / regional pension funds, long-short equity hedge funds focused on Japan, multi-strat funds with Japan sleeves, family offices, and foreign hedge-fund Tokyo branches. The “default domestic prime” for many Japanese-strategy funds.
• Stock loan capability. Largest domestic stock-borrow inventory by depth (cross-shareholding-rooted relationships with Japan Securities Finance and trust-bank custodians); deepest single-name borrow for JPX Prime Market and Standard Market names; competitive on small-cap / Growth Market when borrow is locatable.
• Repo capacity. Top-tier JGB repo book through Nomura’s primary-dealer status; cross-currency repo via global desks (Hong Kong / London / NY).
• Margin lending. Full institutional margin (negotiable margin / 制度信用 / 一般信用 distinction in margin trading and securities finance); risk-based portfolio margin available for sophisticated clients.
• Derivatives. Full TOPIX / Nikkei 225 listed futures / options coverage via JPX; OTC equity swaps, single-stock swaps, equity-linked structured products; full OTC interest-rate / FX / credit derivatives book.
• FX prime. FX prime brokerage with cross-currency margining and global FX desk integration.
• Custody / settlement. Direct JSCC and JASDEC member; in-house custody for client assets with segregation under FIEA cabinet-office-order rules.
• Capital introduction. Established capintro program through the Tokyo prime-finance team — Japan-fund / Japan-sleeve introductions to domestic AMs, regional banks, life insurers, and Asian sovereign wealth.
• Geographic reach. Tokyo head office; Osaka office; integrated with Nomura International (London), Nomura Securities International (NY), Nomura Singapore, Nomura Hong Kong — 24-hour global prime finance book.
• Distinguishing trait. Deepest domestic-borrow and domestic-hedge-fund coverage of any PB provider. The structural advantage is inventory rather than balance-sheet pricing.

Provider 2 — Daiwa Securities Group (Daiwa Securities)

• License footprint. Type I 金商業者 (Daiwa Securities Co. Ltd.); JSDA full member; PTS-eligible; JIPF-covered.
• PB client mix. Domestic AMs, regional pension funds, mid-size hedge funds, and the long tail of domestic institutional clients that prefer a second domestic PB to Nomura. Family-office and high-net-worth coverage via Daiwa Securities adjacent platforms.
• Stock loan capability. Second-deepest domestic borrow inventory after Nomura; strong relationships with JSF and trust-bank custodians; competitive on large-cap and mid-cap borrow.
• Repo capacity. Primary-dealer JGB repo book; cross-currency repo via global subsidiaries.
• Margin lending. Full institutional margin; portfolio-margining selective.
• Derivatives. Full JPX listed-derivatives coverage; OTC equity swaps and structured products; OTC interest-rate / FX / credit derivatives.
• FX prime. FX prime brokerage; smaller global FX book than Nomura / GS / JPM.
• Custody / settlement. Direct JSCC and JASDEC member; in-house custody with segregation.
• Capital introduction. Daiwa Capintro program; smaller / more selective than Nomura’s; tilted toward domestic / Asian capital allocators.
• Geographic reach. Tokyo / Osaka; integrated with Daiwa Capital Markets America, Daiwa Capital Markets Europe, Daiwa Capital Markets Hong Kong / Singapore.
• Distinguishing trait. Default second-domestic-PB choice; structurally important for diversification away from a single Nomura concentration.

Provider 3 — SMBC Nikko Securities

• License footprint. Type I 金商業者 (SMBC Nikko Securities Inc.); JSDA full member; PTS-eligible; JIPF-covered. Megabank-arm structure — owned 100% by SMFG / Sumitomo Mitsui Banking Corporation.
• PB client mix. Domestic institutional AMs, SMBC group cross-shareholding clients, megabank wholesale clients, listed-corporate-side IR / treasury counterparties, mid-size domestic hedge funds. Smaller direct foreign-hedge-fund coverage than the global IBs.
• Stock loan capability. Megabank-group borrow inventory — pulls from SMBC custody book and group cross-shareholding relationships; strong on large-cap and dividend-stable names; smaller small-cap / Growth Market depth than independent IBs.
• Repo capacity. JGB repo book through SMBC group; cross-currency repo via group desks.
• Margin lending. Full institutional margin; bank-affiliated balance-sheet allows competitive cash-margin pricing for group-strategic clients.
• Derivatives. Full JPX listed-derivatives; OTC equity swaps; OTC interest-rate / FX through SMBC banking-book integration; structured products.
• FX prime. SMBC banking-book FX integration; FX prime via SMBC global FX.
• Custody / settlement. Direct JSCC / JASDEC member; in-house custody with segregation; group-trust-bank custody integration available for sophisticated clients.

• PB client mix. Domestic institutional AMs, Mizuho group cross-shareholding clients, AM-One (Mizuho × Dai-ichi Life) adjacency, megabank wholesale clients, mid-size domestic hedge funds with Mizuho group capital relationships.
• Stock loan capability. Megabank-group borrow inventory pulled from Mizuho custody book and group cross-shareholding; strong on large-cap; smaller small-cap depth than independent IBs.
• Repo capacity. JGB repo book through Mizuho group; cross-currency repo via group banking book.
• Margin lending. Full institutional margin; Mizuho banking-book integration allows competitive financing for group-strategic clients.
• Derivatives. Full JPX listed-derivatives; OTC equity swaps; OTC interest-rate / FX through Mizuho banking-book integration; structured products with Mizuho Trust integration for trust-wrapped exposures.
• FX prime. Mizuho banking-book FX integration; FX prime via Mizuho global FX.
• Custody / settlement. Direct JSCC / JASDEC member; in-house custody with segregation; Mizuho Trust & Banking custody integration available.

• Geographic reach. Tokyo head office; integrated with Mizuho Securities USA, Mizuho International (London), and Mizuho group Hong Kong / Singapore offices.
• Distinguishing trait. Dai-ichi Life × AM-One adjacency creates a distinctive insurance-anchored capital-introduction channel.

Provider 5 — SBI Securities (institutional financing sleeve)

• License footprint. Type I 金商業者 (SBI Securities Co., Ltd.); JSDA full member; PTS-eligible; JIPF-covered.
• PB client mix. Atypical PB profile — SBI’s core institutional-financing book is primarily stock-borrow / loan supply to wholesale market rather than full prime brokerage. SBI’s retail-margin franchise (see Japan online brokerage competition for the broker-side context) generates a large in-house stock-borrow inventory that flows to the wholesale stock-loan market. Institutional execution and small-mandate institutional servicing for SBI group AM affiliates.
• Stock loan capability. Distinctively deep retail-rooted borrow inventory — SBI’s retail margin book is the second-largest in Japan, providing a structural supply of borrowable single-name equity for the institutional market via 一般信用 cross-flow into wholesale stock loan.
• Repo capacity. Limited — SBI Securities is not a primary dealer in JGBs at the same scale as Nomura / Daiwa / SMBC Nikko / Mizuho.
• Margin lending. Institutional margin available but smaller institutional balance-sheet than the megabank arms or independent IBs.
• Derivatives. Listed derivatives coverage; OTC derivatives limited; FX margin and CFD (including crypto-CFD overlay).
• FX prime. SBI FX Trade adjacency for FX margin; full FX prime narrower than megabank / global IB providers.
• Custody / settlement. JSCC / JASDEC member through SBI Securities; in-house custody with FIEA segregation.
• Capital introduction. Limited formal capintro; informal introduction via SBI group AM (SBI AM) and SBI group fintech / crypto channel relationships.
• Geographic reach. Tokyo + nationwide retail footprint; smaller global cross-border integration than independent IBs and global IBs.
• Distinguishing trait. Stock-borrow supply rather than full-stack PB — the “PB profile” is structurally different from the other nine providers because SBI’s institutional-financing economics are dominated by the retail-margin-fed stock-borrow rail rather than balance-sheet financing.

Provider 6 — Goldman Sachs Japan

• License footprint. Type I 金商業者 (Goldman Sachs Japan Co., Ltd.); JSDA full member; PTS-eligible; JIPF-covered. Tokyo branch of Goldman Sachs global prime brokerage book.
• PB client mix. Heaviest global-hedge-fund Tokyo-presence coverage — global multi-strategy funds (Citadel, Millennium, Point72, Balyasny, ExodusPoint, etc.) Japan sleeves; Asia macro hedge funds; quant hedge funds with Japan strategies; alternative-credit funds; activist / event-driven funds; long-short equity funds with global mandates. Smaller direct domestic-AM coverage than Nomura / Daiwa.
• Stock loan capability. Largest cross-border borrow inventory — pulls from global Goldman Sachs stock-loan book (London / NY / Hong Kong / Singapore) so a client can locate Japan-name borrow via global subsidiary book; deep on large-cap and mid-cap; competitive on small-cap when borrow is locatable globally.
• Repo capacity. Top-tier global repo book; JGB repo via Tokyo Type I + global cross-currency repo via NY / London.
• Margin lending. Full risk-based portfolio margin (Goldman global-platform margining methodology); cross-margining across asset classes.
• Derivatives. Full JPX listed-derivatives; deepest OTC equity-swap book for Japan-name single-stock swaps among the global IBs; full OTC interest-rate / FX / credit derivatives; structured products.
• FX prime. Goldman global FX prime brokerage; cross-currency margining across global asset classes.
• Custody / settlement. JSCC / JASDEC member; in-house custody for client assets with FIEA segregation; integrated with Goldman global custody infrastructure for cross-border client books.
• Capital introduction. Industry-leading capintro program — Goldman Sachs Tokyo capintro is one of the most established in Asia, with Japan-fund / Japan-sleeve introductions to domestic AMs, life insurers, sovereign wealth funds (across APAC), pension funds, and family offices.
• Geographic reach. Tokyo head office; integrated with Goldman Sachs International (London), Goldman Sachs & Co. (NY), Goldman Sachs Asia (Hong Kong), Goldman Sachs Singapore — 24-hour global prime finance book with Tokyo as the Asia anchor.
• Distinguishing trait. Global hedge-fund prime-broker depth + Asia capintro leadership; the “default global prime” for foreign hedge funds entering Japan.

Provider 7 — Morgan Stanley Japan / MUMSS

• License footprint. Type I 金商業者 — operated through two distinct legal entities: Morgan Stanley MUFG Securities Co., Ltd. (MUMSS, the joint venture with MUFG) for domestic-facing institutional brokerage, and Morgan Stanley Japan Holdings / Morgan Stanley Japan Securities for the Morgan Stanley wholly-owned global-facing institutional book. The MUMSS structure is unique among the global IBs in Japan — a JV that integrates Morgan Stanley investment-banking and institutional-financing capability with MUFG’s domestic distribution.
• PB client mix. Global multi-strategy hedge funds (Japan sleeves), Asia macro funds, quant hedge funds, long-short equity hedge funds, and MUFG group cross-shareholding institutional clients. Strong dual-channel capability — global hedge-fund coverage via Morgan Stanley wholly-owned + domestic institutional coverage via MUMSS.
• Stock loan capability. Combines Morgan Stanley global stock-loan book with MUMSS domestic borrow inventory (drawing from MUFG group custody); strong on large-cap, competitive on mid-cap; small-cap depth depends on MUFG group cross-shareholding availability.
• Repo capacity. Top-tier global repo book; JGB repo via MUMSS primary-dealer status; cross-currency repo via Morgan Stanley global book.
• Margin lending. Full risk-based portfolio margin from Morgan Stanley global platform; cross-margining across asset classes.
• Derivatives. Full JPX listed-derivatives; deep OTC equity swaps via Morgan Stanley global book; OTC interest-rate / FX / credit derivatives; structured products.
• FX prime. Morgan Stanley global FX prime brokerage; cross-currency margining.
• Custody / settlement. JSCC / JASDEC member; in-house custody with FIEA segregation; integrated with MUFG group custody infrastructure (MUTB) for trust-wrapped exposures.
• Capital introduction. Established capintro program — Morgan Stanley Tokyo capintro is structurally important for global hedge funds; MUMSS adds MUFG group capital-introduction channels (MUFG private banking, Mitsubishi UFJ life-insurance-affiliated, and pension fund relationships).
• Geographic reach. Tokyo head office; integrated with Morgan Stanley & Co. International (London), Morgan Stanley & Co. LLC (NY), Morgan Stanley Asia (Hong Kong), Morgan Stanley Asia (Singapore).
• Distinguishing trait. Unique dual-entity structure (wholly-owned + MUFG JV) creates parallel global-hedge-fund and domestic-institutional capability inside one consolidated wholesale franchise.

Provider 8 — JPMorgan Japan

• License footprint. Type I 金商業者 (JPMorgan Securities Japan Co., Ltd.); JSDA full member; PTS-eligible; JIPF-covered. Operates alongside JPMorgan Chase Bank N.A. Tokyo Branch (foreign-bank branch tier) for banking-book FX, repo, and custody integration.
• PB client mix. Global multi-strategy hedge funds (Japan sleeves), Asia macro funds, long-short equity, quant funds, and JPM-coverage institutional asset managers. Strong sovereign-wealth and central-bank custody / financing relationships across Asia. Smaller direct domestic-hedge-fund coverage than Nomura but comparable to GS Japan.
• Stock loan capability. Top-tier global stock-loan book; pulls from JPM global inventory (London / NY / Hong Kong / Singapore); deep on large-cap and mid-cap; competitive on small-cap via global borrow.
• Repo capacity. Top-tier global repo book; JGB repo via Tokyo + cross-currency repo via global desks.
• Margin lending. Full risk-based portfolio margin (JPM global-platform margining); cross-margining across asset classes.
• Derivatives. Full JPX listed-derivatives; deep OTC equity-swap book for Japan single-stock swaps; OTC interest-rate / FX / credit derivatives; structured products. JPM’s banking-book derivatives capability via Tokyo branch is distinctive.
• FX prime. JPM global FX prime brokerage — frequently ranked among the largest FX prime brokers globally; cross-currency margining across asset classes.
• Custody / settlement. JSCC / JASDEC member; in-house custody with FIEA segregation; integrated with JPM global custody infrastructure — JPMorgan Chase Bank Tokyo Branch’s custody platform is one of the largest foreign-bank custody operations in Japan, providing a custody-PB integration not all peers have.
• Capital introduction. Established capintro program via JPM Tokyo prime services and JPM Asset Management Japan adjacency.
• Geographic reach. Tokyo head office; integrated with JPM London, JPM NY, JPM Hong Kong, JPM Singapore — full 24-hour global prime services platform.
• Distinguishing trait. Custody + banking-book + prime services integration — JPM is among the few global IBs that can offer all three inside one Tokyo wholesale relationship, which matters disproportionately for cross-border AM mandates and sovereign-wealth clients.

Provider 9 — Citi Japan (Citigroup Global Markets Japan)

• License footprint. Type I 金商業者 (Citigroup Global Markets Japan Inc.); JSDA full member; PTS-eligible; JIPF-covered. Operates alongside Citibank N.A. Tokyo Branch (foreign-bank branch).
• PB client mix. Global multi-strategy hedge funds (Japan sleeves), Asia macro funds, long-short equity, and Citi global-coverage institutional clients. Significant FX prime and rates-prime overlap with Citi’s global FX / rates franchise.
• Stock loan capability. Citi global stock-loan book; competitive on large-cap and mid-cap; smaller dedicated domestic-borrow franchise than Nomura / Daiwa, but global inventory access compensates.
• Repo capacity. Top-tier global repo book; JGB repo via Tokyo + cross-currency repo via Citi global desks.
• Margin lending. Full risk-based portfolio margin (Citi global-platform); cross-margining.
• Derivatives. Full JPX listed-derivatives; OTC equity swaps; distinctively deep OTC interest-rate / FX derivatives book (Citi’s global rates and FX franchises are among the largest); structured products.
• FX prime. Citi is structurally one of the largest FX prime brokers globally; Tokyo FX prime is a core capability with deep cross-currency margining.
• Custody / settlement. JSCC / JASDEC member; in-house custody with FIEA segregation; integrated with Citi global custody (Citi’s global custody franchise is one of the largest sub-custodian platforms).
• Capital introduction. Capintro program via Citi Tokyo prime services and Citi private bank adjacency; structurally important for hedge funds seeking Asia-wide sovereign and family-office capital.
• Geographic reach. Tokyo head office; integrated with Citi London, Citi NY, Citi Hong Kong, Citi Singapore.
• Distinguishing trait. FX prime + rates derivatives depth — Citi is the structural choice for FX-heavy and rates-heavy strategies; equity PB is competitive but not as deep as GS / MS / JPM in Japan.

Provider 10 — Bank of America Japan (BofA Securities Japan)

• License footprint. Type I 金商業者 (BofA Securities Japan Co., Ltd.); JSDA full member; PTS-eligible; JIPF-covered. Operates alongside Bank of America N.A. Tokyo Branch (foreign-bank branch).
• PB client mix. Global multi-strategy hedge funds (Japan sleeves), Asia long-short equity hedge funds, BofA global-coverage institutional clients, and Asia macro funds. Smaller dedicated PB book in Japan than GS / MS / JPM but materially present.

• Repo capacity. Global repo book; JGB repo via Tokyo + cross-currency repo via global desks.

• Distinguishing trait. Competitive global IB option for hedge funds wanting a fourth global PB diversification away from GS / MS / JPM concentration.

Cross-provider comparison table

Note on collateral haircuts: published indicative ranges (Nomura: cash 0%, JGB 2-5%, listed equity 15-40% by liquidity tier, REIT 25-45%, ETF 15-30%, unlisted negotiated case-by-case) are illustrative — actual haircut grids are bilaterally negotiated per client / fund / concentration and not publicly disclosed in detail.

Stock-loan fee benchmark guide

Public-source benchmarks for the SLB (securities lending and borrowing) market in Japan come from JSDA self-regulatory aggregate publications, Japan Securities Finance published rate references, and JPX margin-trading statistics. Indicative fee ranges for institutional stock borrow in Japan (highly variable by name, concentration, recall risk, corporate-action proximity, and counterparty):

These ranges are public-aggregate indicative levels — not provider-specific quoted rates. Actual fees depend on relationship pricing, inventory source, recall risk, and concentration. Use Japan stock lending market route for the rail-level mechanics.

Capital introduction (capintro) comparison

Capintro is the soft-dollar service that frequently drives PB selection for newly launching or scaling hedge funds. Public-source observation: of the ten providers covered, the established large-scale capintro programs operating in Tokyo are concentrated at:

• Nomura — domestic capintro tilted toward Japan-AM, regional bank, life insurer, and Asian SWF allocators; deepest domestic distribution.
• Goldman Sachs Japan — Asia capintro leader; broadest hedge-fund-launch and Asia-allocator coverage; structurally important for foreign hedge funds entering Japan.
• Morgan Stanley / MUMSS — global capintro plus MUFG group channels; dual coverage of global hedge funds and MUFG-group capital allocators.
• JPMorgan Japan — established global capintro + JPMAM Japan adjacency; strong cross-border capability.
• Daiwa — selective domestic / Asian capintro.
• Citi Japan — Asia-wide capintro with FX-prime angle.
• SMBC Nikko / Mizuho Securities — group-channel capintro (SMBC group / Mizuho × Dai-ichi Life adjacency).
• BofA Japan — smaller in Asia than GS / MS / JPM.

For a hedge fund choosing first / second / third PB diversification, the capintro overlay frequently flips the choice — a fund that economically would prefer Citi for FX prime may select MS or GS instead for capintro coverage.

Boundary cases and caveats

• PB ≠ retail margin. Retail margin trading (制度信用 / 一般信用) is structurally different from institutional PB. Retail margin is standardized broker credit; PB is bilateral institutional financing with portfolio margin, custody, and reporting integration. Do not conflate.
• PB ≠ underwriting. Prime brokerage is wholesale institutional financing and execution; underwriting (新規公開・公募増資・社債引受) is a separate Type I activity covered in Japan underwriting market structure. The same Type I entity often does both, but the businesses are economically and operationally distinct.
• PB ≠ AM. Prime brokerage services AMs and hedge funds; it does not replace 投資運用業. Most global IB PB providers also run separate 投資運用業 subsidiaries (BlackRock, JPMAM, GS AM, MS IM) — different legal entities, different licenses, different fee streams.
• MUMSS dual structure. Morgan Stanley operates in Japan through both MUMSS (the MUFG JV — covers domestic-facing institutional brokerage) and Morgan Stanley Japan Securities (wholly-owned — covers global-facing institutional book). PB clients can interact with either depending on coverage; the dual structure is unique among global IBs in Japan.
• SBI atypical PB profile. SBI Securities is included because its retail-margin-fed stock-borrow supply makes it a structurally important counterparty to the wholesale stock-loan market, not because it runs a tier-1 full-stack PB business. Excluding SBI from this matrix would understate Japan’s stock-loan supply rail.
• BNY Mellon / State Street / custodian-only. BNY Mellon Japan, State Street Japan, and similar custodian-first providers offer asset-administration and securities-lending agency services but are not full-stack PB providers — they are custody and SLB infrastructure providers. Sometimes called “agency lending” rather than “prime brokerage” — covered in Japan stock lending market route.
• UBS / Barclays / BNP / Deutsche / SocGen. Other foreign IBs (UBS Japan, Barclays Japan, BNP Paribas Japan, Deutsche Japan, SocGen Japan) operate institutional-financing capability in Japan but are typically narrower in PB-product breadth than the top 5 global IBs covered; some restructured Asian / Japan equity-PB capacity post-2010. See Foreign-bank Japan retreat for the broader retrenchment context.
• Settlement infrastructure. All ten providers covered are direct JSCC and JASDEC members — that is part of what makes them tier-1 PB providers. Smaller institutional brokers may sub-clear through one of the ten.
• Stock-loan haircut and pricing opacity. Published indicative rates (above) are aggregate market levels; provider-specific haircut grids and stock-loan fees are bilateral and not publicly disclosed. Use this matrix for structural comparison; never quote specific haircut numbers as provider-published facts.
• Cross-border tax / regulatory complexity. Cross-border PB books (especially for foreign hedge funds with Tokyo Japan-only sleeves) require coordination of FIEA, Japanese tax (withholding on dividend, capital-gains treatment for foreign limited partners), and home-country regulation. A “Tokyo PB account” is rarely a single legal relationship.
• Capintro is reputational, not contractual. Capintro programs are soft-dollar services with no contractual SLA; capintro quality varies by team tenure and economic cycle. Public-source assessment is necessarily indicative.
• Provider list completeness. The ten providers covered are the materially active full-stack institutional-PB providers in Tokyo as of the publication date. The matrix does not cover (a) custodian-only providers, (b) narrower global-IB local entities, or (c) provincial / regional securities firms — those are intentionally out of scope. Re-verify provider lineup against the FSA registry annually because foreign-IB scope changes (cf. foreign-bank Japan retreat adjacency).
