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. For settlement-rail context see JASDEC settlement operations. For institutional context see Japan listed financial groups investable universe.

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.

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.

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)
JASDEC participation + per-transaction Fixed annual + per-ticket fee; published in JASDEC tariff
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
