This entry sits under banking index and complements the operating-model deep dives — read it alongside Master Trust Bank operating model, Custody Bank operating model, Japan master trust and custody bank landscape, the cross-camp matrix Japan trust bank vs global custodian comparison matrix, and the operating comparison trust-bank custody operating comparison. Pair it with the entity pages MTBJ, CBJ, MUFG Trust, SMTB, Mizuho Trust, SMBC Trust, BNY Mellon Japan, State Street Japan, and JP Morgan Japan.

TL;DR
Trust-bank fee economics in Japan are dominated by three drivers: AUC-bps pricing on securities custody and 投信受託, pension trust admin fees on long-duration mandates, and real-estate trust fees on the full-service trust-bank side. Granular fee schedules are largely non-public — only aggregate-level inference is possible from shareholder consolidated disclosure and individual 投信 prospectuses (信託約款). Across 6 Japan trust banks (MTBJ, CBJ, MUFG Trust, SMTB, Mizuho Trust, SMBC Trust) and 4 global custodians (BNY Mellon, State Street, Citi, JPM), the structural pricing model is similar — AUC bps + per-transaction fees + revenue-share lending — but the mix and the pricing power differ sharply by client segment. Domestic custody-only specialists (MTBJ, CBJ) anchor low bps on volume; full-service trust banks bundle higher-margin real-estate / pension / inheritance fees with custody; global custodians charge a relative premium for cross-border + ICSD connectivity. Mandate-level pricing is not publicly disclosed; the fee-magnitude detail in this entry is therefore industry-level inference rather than entity-specific fact, and is quarantined to .opinions/banking/trust-bank-fee-structure-comparison.md.

Custody fee mechanics
| Fee component | Pricing logic | Typical magnitude (industry inference, not entity-specific) |
|---|
Pension trust admin fees
| Component | Pricing logic | Magnitude inference |
|---|
Securities investment trust admin fees
| Component | Pricing logic | Source for public observation |
|---|
| Fund accounting / NAV calc | Bundled into 受託会社報酬 | Stated only as bundled rate |
| Distribution processing | Bundled | Not separately disclosed |
Across the 投信 industry the 受託会社報酬 is typically a small fraction of total fund expense ratio — the bulk of the expense ratio sits at the asset manager (運用会社報酬) and the distributor (販売会社報酬) rather than the trust bank.
Real-estate trust fees (full-service trust banks only)
| Component | Pricing logic | Magnitude |
|---|
This line is absent at MTBJ and CBJ — the custody-only specialists do not run real-estate trust.
Cross-bank fee-economy matrix (10 entities)

Pricing-power summary
| Service | Strongest pricing power | Reason |
|---|
| GPIF-scale domestic custody | MTBJ / CBJ | Utility scale + GPIF tender competition between the two |
| Mass-investor 投信 受託会社 | MTBJ / CBJ | Volume utility, tight bps, but volume drives revenue |
| Corp-DB pension trust admin | MTBJ / CBJ / megabank trust arms | Mixed — utility specialists win on bps, full-service wins on bundling |
| Real-estate trust setup | MUFG Trust / SMTB / Mizuho Trust | Specialized + relationship-driven; no competition from custody-only specialists |
| Inheritance / 相続 / 遺言 | MUFG Trust / SMTB / Mizuho Trust / SMBC Trust | High-margin wealth-management line; absent at custody-only specialists and at global custodians |
| Cross-border / foreign-asset custody | BNY / State Street / JPM / Citi | Cross-border ICSD + sub-custody network premium |
| Securities lending (large institutional) | BNY / State Street / JPM (and MTBJ / CBJ on JP equity domestic flows) | Mixed; agent-lender scale wins |
| US-listed JP-securities (ADR) | BNY / Citi / JPM | ADR depository fees |
Implied fee revenue (very rough industry inference)
Granular line-item fee revenue per entity is not publicly disclosed. The order-of-magnitude inference (industry-level only, not entity-specific guarantee) is:
| Implied revenue per ¥100tn AUC at custody-only specialist | Industry-rough inference (not entity-specific) |
|---|
| If average custody bps = 0.5 bp/year | ¥50bn / year revenue |
| If average custody bps = 1 bp/year | ¥100bn / year revenue |
| If average custody bps = 2 bps/year | ¥200bn / year revenue |
The per-entity gross custody revenue implied by applying these hypothetical bps to MTBJ / CBJ AUC is industry-level inference only and is not attributable to any disclosed fee line; that inference is quarantined to .opinions/banking/trust-bank-fee-structure-comparison.md.
Fee trends
| Trend | Effect on trust-bank P&L |
|---|
| Passive-fund AUM growth | Volume up, per-bp down → modest net revenue growth, margin compression |
| Foreign-investor JP allocation growth | Foreign sub-custody revenue at MTBJ / CBJ tied to global-custodian fee schedules |
| NISA expansion (2024 onward) | Volume growth in 投信 受託会社 fees |
| DC pension reform (2025 onward) | DC member-balance reporting volume growth |
| Real-estate market cyclicality | Volatile for full-service trust banks; absent for custody-only |
Why granular per-bank fee tables are impossible to publish externally
| Reason | Impact |
|---|
| Custody fees are mandate-specific contracts | No single tariff per bank |
| Group-consolidated disclosure aggregates many fee lines | Cannot isolate custody from other trust-bank fees |
| 投信 受託会社報酬 disclosed only per fund in each 信託約款 | Manual aggregation needed across all funds |
| Pension trust admin fees are individually negotiated | Including GPIF |
| Global-custodian Japan units do not disclose JP-specific lines | Only parent-level aggregates |
| Real-estate trust fees vary by deal | Cannot benchmark to a per-bp standard |
Public observable per-fund 投信 受託会社報酬
For a structured public-data study, the 投信 受託会社報酬 across major fund families is the most observable line:
| Asset manager family | 受託会社 (most common) | Typical 受託会社報酬 (annualized) |
|---|
A precise study would scrape 信託約款 of leading funds for the documented per-fund 受託会社報酬 — the data is public per fund but laborious to aggregate.
Regulatory fee constraints
| Layer | Constraint |
|---|
| 信託業法 fiduciary-duty rules | Fees must be fair and disclosed; conflict-of-interest controls |
| 金商法 投信運用報告書 disclosure | Fund-level fees including 受託会社報酬 must be disclosed |
| Pension fund 受託者責任 | Fees subject to pension trustee fiduciary review |
| Stewardship Code | Voluntary; encourages transparent fee disclosure where possible |
| FSA supervisory guidance | General reasonableness review; no rate-cap regime |
Accounting view
| Item | Entity that recognizes |
|---|
| Custody / admin fees as revenue | Trust bank P&L |
| Custody / admin fees as expense | Asset owner / 投信ファンド |
| Off-balance-sheet trust AUC | Not on trust bank’s balance sheet |
| On-balance settlement-account residuals | Trust bank’s balance sheet (small) |
| Lending revenue share | Trust bank revenue + beneficial-owner revenue (split per contract) |
Comparability problems
| Problem | Effect |
|---|
| AUC vs AuA definition variation | ”Assets under custody” vs “assets under administration” measured differently across entities; cross-entity AUC numbers are not strictly comparable |
| Mix-effect across asset classes | One entity’s mix-weight (domestic equity / JGB / foreign / 投信) differs sharply from another’s |
| Domestic-only vs global aggregation | Global custodians report parent-level numbers; JP-specific lines opaque |
| 投信 受託会社 fees per fund vs per-bank aggregate | Per-fund disclosure can be aggregated manually but is not officially aggregated |
| Real-estate fees revenue lumpy | Full-service trust banks have lumpy deal-driven real-estate fees |
Fee cost-side from infrastructure participation
| Infrastructure | Fee paid by trust bank (input cost) |
|---|
| [[banking/jasdec-settlement-operations | JASDEC]] participation + per-transaction |
| JSCC clearing | Clearing-membership cost + per-trade clearing fee |
| BoJ JGB book-entry | BoJ system participation cost |
| BoJ-net cash settlement | Per-transaction cost |
| 全銀ネット | Per-transaction cost |
| ICSD (via global custodians) | Pass-through global-custody fee |
| Voting platform (ICJ etc.) | Platform fee |
