ODX START security token secondary market

Wiki route

This page belongs in securities index as the venue-mechanics deepening of Osaka Digital Exchange and as the secondary-market sibling of Japan security token secondary market route. Read it with PTS liquidity data guide for the venue / participant separation logic, best execution / SOR / PTS for the routing-policy context, and Japan market infrastructure map for where ODX sits between TSE / Japannext PTS and JSCC / JASDEC. The cross-domain bridge is Progmat stablecoin route, because tokenized cash-leg payment infrastructure is the missing rail for full atomic DvP in Japanese ST secondary markets.

TL;DR

ODX (Osaka Digital Exchange) is a Japanese FIEA-registered PTS operator founded as a joint venture led by SBI HD, Sumitomo Mitsui Trust Holdings (SuMi TRUST / Sumishin), and Nomura HD, with additional securities-industry participation. Its START market, launched on 2023-12-25, is publicly described as Japan’s first secondary trading PTS for security tokens (ST), covering tokenized equity, tokenized bonds, and tokenized real-estate beneficial interests issued under the FIEA electronically recorded transferable rights framework. Trading on START is intermediated exclusively through accepted securities-firm trading participants; ODX itself does not face retail investors directly. Settlement integrates with JSCC and JASDEC for the listed-securities adjacency and with token-platform infrastructure (e.g. Progmat, BOOSTRY / ibet) for the on-token transfer leg. New issue listings on START go through an Approval to Register (ATR) gating process operated by ODX before secondary trading is enabled.

Ownership and strategic alignment

ODX’s founding capital structure is a deliberate cross-sector coalition rather than a single-house product:

Anchor	Strategic interest
[[megabanks/sbi-hd	SBI HD]] (and SBI group entities)
[[securities-firms/nomura-hd	Nomura HD]]
Sumitomo Mitsui Trust Group / SBI Sumishin Net Bank lineage	Trust-bank custody / recordkeeping role for tokenized trust-beneficial-interest products; cash-leg infrastructure.
Other securities firms (joining as participants and / or shareholders over time)	Distribution breadth for ST issuer market; participation in the only Japanese ST secondary venue.

The coalition design is a feature, not a bug: a single-firm-owned ST PTS would lack the issuer- and distribution-side breadth needed to bootstrap a market. The trade-off is governance friction common to JV venues.

What is a “security token” in this venue context

A security token in the Japanese regulatory frame is most commonly:

An electronically recorded transferable right under FIEA, typically a Type II beneficial interest segment that has been “electronically recorded” using DLT / blockchain infrastructure;
Or other instruments fitted into the FIEA “tokenized security” treatment via FSA notice / cabinet office order.

In practice, the ST issues that reach START’s secondary market include:

Asset type	Example structure	Issuance platform
Tokenized real-estate beneficial interests	Trust-beneficial-interest in real-estate-holding trust, tokenized for DLT recordkeeping	[[payment-firms/progmat
Tokenized bonds	Digital bond issued as electronically recorded right	BOOSTRY (Nomura group), [[payment-firms/progmat
Tokenized equity / private-equity beneficial interests	Tokenized fund / SPC equity interests where allowed by FIEA scope	Platform varies

The token platform handles issuance, transfer, and recordkeeping; ODX provides the secondary-market venue function; the securities firm is the customer-facing intermediary; the trust bank or custodian holds the underlying asset rights. This is a five-party architecture rather than the three-party (issuer / exchange / broker) cash equity architecture.

ATR — Approval to Register

ATR (Approval to Register) is the gating step ODX runs before an issue is enabled for secondary trading on START. The conceptual sequence:

Issuer requests registration through a sponsoring securities firm (trading participant).
ODX evaluates issuer disclosure, token platform integration, custody / trustee arrangement, transfer mechanics, and rule compliance with JSDA unlisted-PTS rules and ODX’s own market rules.
ODX issues an ATR for issues that meet eligibility criteria.
Issue is enabled for trading under START’s rules.
Ongoing monitoring verifies disclosure, market-integrity, and operational continuity.

ATR is not equivalent to a TSE listing examination. TSE listing is a public-market admission with full continuous disclosure obligations and broad retail accessibility. ATR is a PTS admission for ST issues that are typically restricted to specified investor categories with constrained disclosure intensity.

JSCC and JASDEC integration

The settlement question for ODX has two answers because there are two market scopes:

Cash-equity PTS scope. When ODX operates as a conventional cash-equity PTS for listed equities (a narrower function than Japannext), trades clear through JSCC under the PTS clearing arrangement and settle via JASDEC book-entry on the standard cash-equity cycle.

Security-token (START) scope. Tokenized securities clear and settle differently because the underlying asset rights are recorded on the token platform (Progmat / BOOSTRY / ibet) rather than at JASDEC for the token leg. Cash leg settlement uses standard yen settlement rails (trust-bank or bank wire); the token-leg transfer uses the platform’s transfer mechanics. True atomic DvP between cash leg and token leg has been the subject of multiple Japanese bank / market-infrastructure experiments (e.g. DCJPY, tokenized deposit prototypes) and remains in development as a market-infrastructure thesis rather than a fully deployed standard at ST PTS scale.

For an analyst, the right framing is:

Listed cash equity = TSE / JSCC / JASDEC, mature.
Listed cash equity PTS (Japannext / Cboe Japan / ODX equity PTS) = Same JSCC / JASDEC settlement, mature.
ST PTS (START) = Token-platform transfer + parallel cash-leg payment; DvP design varies; tokenized-cash-leg integration still maturing.

Trade flow walkthrough

A simplified trade-flow walkthrough for a tokenized real-estate beneficial interest traded on START:

Investor (specified-investor scope)
  -> Securities firm (ODX trading participant, FIEA Type I + tokenized-security distribution scope)
    -> Order entry to ODX START matching engine
      -> Match against counterparty order
        -> Trade confirmation to both participants
          -> Token transfer leg via token platform (Progmat / BOOSTRY / ibet)
          -> Cash leg via trust-bank / bank settlement
            -> Custody / recordkeeping update at trustee / platform
              -> Investor statement update at securities firm

The contrast with cash-equity flow (see infrastructure map) is that the token leg replaces the JASDEC book-entry transfer with the token-platform transfer, and the cash leg may use specialized tokenized-deposit / stablecoin experiments where available rather than only conventional Zengin / BOJ-NET rails.

Investor eligibility and scope

START operates under the JSDA unlisted-PTS framework, which constrains the investor scope for many ST issues to specified investor categories or otherwise narrower-than-retail audiences. The practical reading:

Many ST issues are not available to ordinary retail investors at retail online brokers in the same way listed equities are.
The investor-eligibility check is run at the securities firm trading-participant level.
Disclosure intensity is lower than for TSE-listed equities; investor protection relies on the specified-investor framework, issuer-level disclosure, and trading-participant suitability checks.
Cross-border distribution into Japan via ODX trading participants for non-Japanese investors is constrained by both FIEA and the participant’s own customer-acceptance policy.

For asset managers and institutional allocators, this means ST exposure typically requires either direct ST PTS access through a participant, or wrapping inside a publicly offered investment trust / privately placed investment trust structure that itself holds ST instruments.

Regulatory and self-regulatory framework

Layer	Role
FSA	Authorizes Type I FIBO with PTS scope; supervises the unlisted-PTS framework; published 2022-06-22 Market System Working Group interim report addressing ST circulation via PTS. ^[FSA financial instruments operator list; FSA 2022-06-22 Market System Working Group interim report; ODX START launch page]
JSDA	Self-regulatory body; created rules for PTS trading of unlisted securities including tokenized securities after the FSA 2022 interim report; defines `unlisted approved PTS issue` scope.
Japan STO Association	Industry discussion forum on STO market development; not a primary regulator but feeds into JSDA / FSA rule-design context.
JSCC / JASDEC	Settlement infrastructure for the cash-equity scope of ODX.
Token platforms	Operate transfer / lifecycle mechanics under their own platform rules; subject to trust-bank / custody supervision where relevant.
