Mitsui & Co. Digital Asset Management

What Mitsui & Co. Digital Asset Management does

Mitsui & Co. Digital Asset Management Co., Ltd. (三井物産デジタル・アセットマネジメント株式会社) is a Tokyo-based digital asset management firm established in April 2020 as a joint venture between Mitsui & Co. (53% shareholder), LayerX (35%), SMBC Nikko Securities (5%), Mitsui Sumitomo Trust Bank (5%), and minority partners. The company operates Japan's first digital-native asset management platform, issuing and managing blockchain-based security tokens that fractionalize institutional-grade real estate and infrastructure assets for retail and professional investors. Its core product is ALTERNA, a smartphone application enabling investments from 100,000 yen per unit, supported by ALTERNA PRO for qualified professional investors, ALTERNA Trust (a joint venture with Mitsui Sumitomo Trust Bank established July 2025) for digital securities trust services, and そだつ貯蓄 for real-estate-financing-linked products. Underlying technology integrates consortium blockchain platforms including Progmat SaaS and ibet for Fin (BOOSTRY) for security token lifecycle management.

The company holds Kanto Finance Bureau Financial Instruments Business registration (No. 3277) covering Type I, Type II, and Investment Management Business, plus real estate broker registration and memberships in JSDA and JITA. As of December 2025, MDM reported approximately 2,477 billion yen in total assets under management across 49 properties and 19 public digital securities funds, with cumulative issuance surpassing 500 billion yen by April 2025. Revenue derives from three streams: AUM-based asset management fees (subscription/recurring), distribution and transaction fees from sales of digital securities products, and subscription fees from ALTERNA PRO professional investor services. Distribution combines a direct-to-consumer channel (ALTERNA app), enterprise sales for corporate and institutional clients, and a multi-layered partner channel spanning regional banks (Hokuyo, Hokuriku, Miyazaki Taiyo, Saniku, Joyo), major securities firms (Daiwa, SBI, Tokai Tokyo), digital banks (Sony Bank, Tokyo Star Bank, SBI Sumishin Net Bank), IFAs (Innovation IFA Consulting, W&P), and corporate card issuers (JFR Card).

The company has pursued rapid geographic and channel expansion since 2024, opening regional branches in Okinawa (May 2024), Osaka (July 2025), and Sapporo (November 2025), while securing the Tokyo Financial Award 2025 in the Financial Innovation Category. Its strategic positioning is anchored by the Mitsui group deal pipeline, LayerX blockchain and LLM technology capabilities, and a vertically integrated platform combining distribution, trust, custody, and asset management under one roof.

Expansion highlights6 records

Direct peers

• BOOSTRY Inc. BOOSTRY develops the ibet for Fin consortium blockchain platform used by MDM for security token issuance and management. It both enables and competes in the Japanese digital securities infrastructure layer, making it the most direct technology-tier peer.
• Progmat, Inc. Progmat provides the digital asset issuance and management platform (Progmat SaaS) that MDM uses, while also operating as an independent tokenization infrastructure provider to other issuers in Japan. It is a direct technology peer and at times a competitor for new digital securities mandates.
• Securitize: Securitize is a leading US-based platform for tokenization of real-world assets and digital securities issuance. It is the closest international counterpart in the institutional RWA tokenization space and competes for the same digital securities mandates that increasingly cross borders.

Emerging players

• Ondo Finance: Ondo Finance is a US-based RWA tokenization platform best known for tokenized US Treasuries and money market products. It is comparable as an institutional RWA tokenization play focused on alternative yield products distributed to both retail and professional investors.
• Tokeny: Tokeny is a European-based tokenization infrastructure platform focused on issuance and lifecycle management of security tokens. It competes with MDM/BOOSTRY/Progmat in the broader RWA tokenization stack and serves similar institutional issuers.
• WealthNavi Inc. WealthNavi is Japan's leading robo-advisor and digital wealth platform, providing automated portfolio management to retail investors. It overlaps with ALTERNA as a Japanese digital wealth channel serving mass-affluent retail with diversified investment products.
• Monex Group / Monex Crypto Bank: Monex Group operates online brokerage, crypto exchange (Coincheck), and is moving into tokenization and digital asset products in Japan. It overlaps with MDM as a Japanese digital asset services provider targeting retail and professional investors.

Broad incumbents

• SBI Holdings (SBI Securities): SBI is a major Japanese online financial conglomerate with a large securities business (SBI Securities) that is both an ALTERNA distribution partner and an investor via SBI Sumishin Net Bank. Comparable as a Japanese digital-finance incumbent with adjacent tokenization ambitions through group firms.
• Daiwa Securities Group: Daiwa Securities is a major Japanese securities firm and a lead distribution partner for MDM's large STOs (e.g., 300B yen Nagoya Prime Office). It both distributes MDM products and is developing competing digital securities capabilities within its broader capital markets business.
• Nomura Real Assets / Nomura Holdings tokenization initiatives: Nomura Holdings is one of Japan's largest financial groups and has launched real asset tokenization efforts via Nomura Real Assets and related initiatives. It is comparable as a broad incumbent exploring digital securities issuance alongside traditional asset management at much greater scale.
