TL;DR
The JGB Special Participants system (国債市場特別参加者制度) is a Ministry of Finance framework introduced in October 2004. Participants accept auction-bidding, purchase, secondary-market-liquidity, and information-provision responsibilities under MOF’s published terms. The linked MOF list dated 27 December 2023 contains 19 companies; a “current” count must be taken from the latest MOF list rather than assumed.
MOF’s terms require sufficient secondary-market liquidity but do not state a generic continuous two-sided-quote obligation. Entitlements include meetings with MOF and access, subject to detailed conditions, to Non-Price Competitive Auctions I and II, buybacks, STRIPS, enhanced-liquidity auctions, and preferential counterparty selection for interest-rate swaps.
The Japanese system is conceptually similar to the US primary dealer system (administered by the New York Fed) and the UK gilt-edged market maker (GEMM) system, but with distinct operational features that reflect Japanese market structure and MoF’s auction-design approach.
For FinWiki, this entry covers the Special Participant list and tiering, obligations, benefits, the Non-Price Competitive Auction mechanism, and structural comparisons with the US and UK primary dealer systems.
Wiki route
This entry sits under derivatives index in the JGB / rates cluster. Read it against jgb-futures-curve for the futures market the Special Participants serve, jgb-inflation-linked-bond-jgbi for the JGBi auctions they participate in, and jgb-repo-market-japan for the repo market that supports their inventory financing. The MoF issuance program context is anchored at money market; the BoJ-policy interface is at BoJ open market operations.

List Composition (Typical)
The list is entity-specific and changes over time. This page therefore does not reconstruct an illustrative roster from brand names. Use the latest file linked by MOF; the cited 27 December 2023 snapshot contains the exact 19 legal-entity names for that date.
Obligations of Special Participants
Special Participants accept the following obligations under MoF rules:
| Obligation | Detail |
|---|---|
| Bidding responsibility | Submit bids whose total face amount meets the formula in MOF’s terms for each applicable auction |
| Purchase responsibility | Meet the minimum successful-purchase proportions specified by maturity zone in the terms |
| Secondary-market responsibility | Provide sufficient liquidity; MOF considers quote presentation and outright and futures transaction activity |
| Information responsibility | Provide information requested by MOF concerning JGB markets and operations |
| Ongoing status | Subject to the designation, suspension, and revocation conditions in the current terms |

MOF’s terms provide for monitoring and interviews in principle quarterly; they do not describe a generic annual-renewal cycle.
Benefits of Special Participant Status
In exchange for the obligations, Special Participants receive:
| Benefit | Detail |
|---|---|
| Non-Price Competitive Auction I | Conducted simultaneously with the competitive auction; awarded at the weighted-average accepted price within the applicable limit |
| Non-Price Competitive Auction II | Conducted after the auction on the same day; awarded at the weighted-average accepted price within the applicable entitlement |
| MOF meetings | Participation in meetings concerning debt-management policy and markets |
| Other conditional access | Buybacks, STRIPS, enhanced-liquidity auctions, and preferential interest-rate-swap counterparty selection under the terms |
Source: ^[source:https://www.mof.go.jp/english/policy/jgbs/debt_management/pd/20240425.pdf]
These are conditional entitlements, not guaranteed allocations. Limits and performance-based calculations must be read from the current terms and dated auction notice.
Auction Mechanics in the JGB System
The JGB auction process accommodates Special Participants alongside other bidders:
| Auction component | Eligibility / mechanism |
|---|---|
| Price-competitive auction | Open to all qualified bidders (Special Participants + others); allocation by competitive bid |
| Non-Price Competitive Auction I | Special Participants; conducted simultaneously with the competitive auction and priced at the weighted-average accepted price |
| Non-Price Competitive Auction II | Special Participants; conducted after the auction on the same day and priced at the weighted-average accepted price |
| Exact terms | Product, amount, limits, and bidding method follow the dated auction notice and current MOF rules |
Source: ^[source:https://www.mof.go.jp/english/policy/jgbs/debt_management/pd/20240425.pdf]
The entitlement calculations refer to historical participation under MOF’s rules; this page does not recast them as an unconditional allocation.
Comparison with US Primary Dealer System
The New York Fed’s “primary dealer” designation belongs to a different legal and operational framework. A valid comparison must align the date, administrator, auction role, central-bank-counterparty role, reporting duties, and securities scope. It should not import US obligations into the MOF terms; the Japan-side facts on this page come only from MOF’s published framework.
Comparison with UK GEMM System
The UK GEMM framework is likewise separate. Counts, subcategories, quoting duties, and auction access change and require current UK DMO sources. No UK detail is used to infer a Japanese obligation or entitlement here.
Why the System Matters
The Special Participants system is critical to:
- Auction-policy rationale: The framework is designed to support stable issuance and dialogue; it does not guarantee an auction result or price.
- Secondary market liquidity: MOF requires sufficient liquidity and evaluates the activity described in its terms.
- Information flow to MoF: The terms require information provision and provide for meetings; how MOF uses feedback remains a policy decision.
- Conditional auction access: Status can provide access to the enumerated non-price and debt-management operations under their detailed conditions.
- Published accountability: MOF publishes the participant list and terms, allowing designation status to be checked at a stated date.
