Read it with [[payment-firms/progmat|Progmat]], [[fintech/jp-stablecoin-progmat|Progmat stablecoin / digital asset route]], [[securities/osaka-digital-exchange|ODX]], and [[trust-banks/smtb|SMTB]]. Use this page for digital securities, security-token trust, beneficiary-certificate issuing trust, and trust-company platform questions. ## TL;DR オルタナ信託は、Mitsui & Co. Digital Asset Management (MDM) と [[trust-banks/smtb|Sumitomo Mitsui Trust Bank]] が設立した digital-securities-focused trust company。SMTG English release は Alterna Trust を digital securities に特化した trust company と説明し、beneficiary-certificate issuing trust の administration が ST issuance で重要な役割を持つと述べる。^[source:smtg-alterna-release-2025] MDM release は、ALTERNA brand のもとで ST の取得・運用・受託・販売を一気通貫で提供する体制を構築し、[[payment-firms/progmat|Progmat]] が Progmat SaaS を MDM と Alterna Trust に提供すると説明する。^[source:mdm-alterna-release-2025] FSA trust-company workbook では、オルタナ信託株式会社が 2025-07-03 免許日、法人番号 9010001253166、所在地 東京都中央区日本橋堀留町1-9-8 として掲載される。^[source:fsa-trust-list-2026] ## Entity boundary | Item | Reading | |---|---| | Legal name | オルタナ信託株式会社 / Alterna Trust Co., Ltd.。^[source:mdm-alterna-release-2025][source:smtg-alterna-release-2025] | | Licence / registry | FSA `sintaku01.xlsx` lists オルタナ信託株式会社 in the trust-company list with 2025-07-03 licence date.^[source:fsa-trust-list-2026] | | Address | 東京都中央区日本橋堀留町1-9-8; SMTG release specifies Ningyo-cho PREX 3F.^[source:fsa-trust-list-2026][source:smtg-alterna-release-2025] | | Representative | MDM and SMTG releases name Shosaku Ikeda / 池田匠作 as representative president / CEO.^[source:mdm-alterna-release-2025][source:smtg-alterna-release-2025] | | Capital / ownership | SMTG release gives capital including capital reserves JPY 665mn and investment ratio MDM 85.1%, SuMiTB 14.9%.^[source:smtg-alterna-release-2025] | This is not a securities broker, exchange, or stablecoin issuer page. The useful boundary is the **trustee / trust-administration role** for security-token fund structures. ## Digital securities trust role | Function | FinWiki relevance | |---|---| | Beneficiary-certificate issuing trust | SMTG release says Alterna Trust specializes in administration of a trust with certificates of beneficial interest, a crucial role in digital securities issuance.^[source:smtg-alterna-release-2025] | | Trustee in ST issuance schemes | SMTG release says Alterna Trust collaborates with asset managers, securities firms and others as trustee in schemes to issue digital securities.^[source:smtg-alterna-release-2025] | | ALTERNA integration | MDM release says MDM and Alterna Trust built a setup for acquisition, operation, trust administration and sale of ST under the ALTERNA brand.^[source:mdm-alterna-release-2025] | | Progmat SaaS | MDM release says Progmat provides Progmat SaaS to MDM and Alterna Trust, supporting digital asset issuance / management infrastructure.^[source:mdm-alterna-release-2025] | | Asset class scope | SMTG release says Alterna Trust initially focuses on real estate, then intends to add other alternative assets, corporate bonds and claims held by SuMiTB.^[source:smtg-alterna-release-2025] | ## Group / alliance relationship ### MDM side MDM is the platform / asset-management side of the structure. Its release says MDM has built the ALTERNA service for individual investors and operates ST fund formation / management / sale. It also says its use of Progmat SaaS lets MDM complete ST management itself, reducing scheme costs and aiming to maximize returns to investors.^[source:mdm-alterna-release-2025] ### Sumitomo Mitsui Trust side [[trust-banks/smtb|SuMiTB]] supplies trust know-how and the trust-bank group route. SMTG release says SuMiTB and MDM entered a business alliance for digital securities, including joint management of Alterna Trust, dispatching experts / sharing know-how, forming products using ALTERNA, introducing assets including claims held or sourced by the bank, and providing funds to MDM while MDM uses SuMiTB's sales network.^[source:smtg-alterna-release-2025] ### Progmat boundary [[payment-firms/progmat|Progmat]] is infrastructure, not the trust company. MDM release describes Progmat SaaS as a product enabling financial institutions to start digital-asset-related businesses such as ledger-management and custody functions without building their own blockchain / DLT nodes.^[source:mdm-alterna-release-2025] ## Why standalone page matters 1. **Trust layer is explicit**: Many ST pages over-emphasize platform or exchange. Alterna Trust gives FinWiki a trustee / beneficiary-certificate issuing trust anchor. 2. **It links trust banking to fintech**: The page bridges [[trust-banks/smtb]], [[payment-firms/progmat]], ALTERNA and security-token fund issuance. 3. **It is not a soft partnership note**: FSA list and company releases support a concrete regulated entity, not only a concept. 4. **It limits role confusion**: Use [[securities/osaka-digital-exchange|ODX]] for market venue, [[payment-firms/progmat|Progmat]] for infrastructure, and this page for trust administration. ## Related - [[trust-banks/INDEX]] - [[trust-banks/trust-companies-japan-index]] - [[trust-banks/smtb]] - [[payment-firms/progmat]] - [[fintech/jp-stablecoin-progmat]] - [[securities/osaka-digital-exchange]] - [[financial-licenses/securities-license-stack]] - [[INDEX|FinWiki index]] ## Sources - **FSA**: 信託会社一覧 `sintaku01.xlsx`（オルタナ信託株式会社、2025-07-03 免許日、2026-06-24 確認）https://www.fsa.go.jp/menkyo/menkyoj/sintaku01.xlsx - **Mitsui & Co.
