Japan’s Enterprise Blockchain Partnerships Move to Production

Japan’s enterprise blockchain adoption has moved from theory to production infrastructure across four protocols since 2023: Quant Network for banking settlement, XDC Network for trade finance, Algorand for carbon markets, and Ripple’s XRP for cross-border payments. The retail crypto market has noticed almost none of it.

The deployments are concrete. Quant Network (QNT) and Dentsu Soken, a Tokyo-based financial technology company that builds payment and settlement systems for Japan’s largest banks, formed a production partnership in January 2026 to build programmable settlement infrastructure. SBI Holdings established a 300-million-yen joint venture with XDC Network in December 2023 to digitize Japan’s trade finance sector, completing its first cross-platform proof-of-concept by May 2024. In January 2026, Mitsui O.S.K. Lines (MOL), the Japanese shipping conglomerate, and ITOCHU Corporation, one of Japan’s five largest trading houses, used Algorand-based infrastructure to execute Japan’s first cross-sector environmental attribute certificate trade. SBI VC Trade began distributing Ripple’s RLUSD stablecoin on March 31, 2026, the first regulated launch of that product anywhere in Asia.

Programmable Settlement Arrives at Japan’s Banks

Overledger Inside BOJNET

The Quant-Dentsu Soken partnership, announced January 14, 2026, puts Quant’s Overledger technology (an interoperability layer that connects disparate blockchains and legacy financial systems through a standardized API gateway) inside the operating reach of Japan’s major financial institutions. Dentsu Soken brings operational depth to the arrangement: the company built StreamR, a settlement management system compatible with BOJNET (the Bank of Japan’s Real-Time Gross Settlement system), alongside global core banking platforms, SWIFT reconciliation systems, and CLS settlement infrastructure. Quant Network’s interbank settlement infrastructure brings the institutional credentials: regulated pilots with the Bank of England, the Bank for International Settlements (BIS) on Project Rosalind, the European Central Bank, the UK Regulated Liability Network, and the Great Britain Tokenised Deposit (GBTD) project, which involved HSBC and Barclays.

Quant’s Overledger conforms to the ISO 20022 financial messaging standard, the same standard required by SWIFT, central banks, and commercial banks for cross-border settlement. That conformance matters for the Japan deployment specifically: tokenized settlement rails can connect to existing BOJNET infrastructure without a translation layer between them.

Banks are preparing for tokenised deposits, new forms of digital money and more interoperable settlement systems. Partnering with Dentsu Soken lets us support Japan’s transition to digital assets and tokenised money with technology that is proven, compliant and designed for institutions.

Gilbert Verdian, founder and CEO of Quant Network, in the January 14 partnership announcement.

Dentsu Soken’s Chie Ito, executive officer and head of business development, described 2026 as “a pivotal moment in the evolution of stablecoins” and committed to supporting “the safe and flexible social implementation of programmable payments.”

Four Priorities for Japan’s Banks

The partnership addresses four operating areas. Programmable settlement coordinates money and asset flows across both legacy payment systems and new tokenized rails simultaneously, rather than routing between them sequentially. Tokenized deposit logic enables conditional payments and synchronization with existing ledgers. Treasury automation cuts intraday liquidity management and reduces manual reconciliation. Interoperability solutions, built on Quant’s ISO 20022 architecture, are adapted to Japan’s regulatory requirements, giving Japanese banks a single implementation path across all four.

Bank of Japan governor Kazuo Ueda confirmed in a March 2026 speech that a central bank sandbox is already running “to enable the use of central bank money for a wide range of settlements on blockchains,” testing settlement in the form of current account deposits. The Quant-Dentsu Soken infrastructure connects to exactly that transition point, bridging the tokenized money layer with the legacy systems Japan’s banking economy runs on today.

SBI and Two Separate Chains

SBI Holdings, one of Japan’s largest financial holding companies, runs two distinct blockchain strategies, each handling a different problem within the same institutional economy.

The Trade Finance Channel

In December 2023, SBI Holdings established SBI XDC Network APAC Co., Ltd., a joint venture with TradeFinex Tech, a UAE-based firm that operates XDC Network (XDC), a hybrid enterprise blockchain designed specifically for trade finance and cross-border settlement. SBI Holdings holds 60% of the 300-million-yen capitalization.

Japan’s trade finance sector processes hundreds of trillions of yen in annual transactions, much of it still running on paper documents, physical trade instruments, and legacy correspondent banking relationships. XDC Network’s expansion into Japan’s trade finance market targets that operational friction directly. The network settles transactions in two seconds, charges gas fees near $0.0001, and conforms to the ISO 20022 messaging standard used by financial institutions for cross-border exchange.

In May 2024, the joint venture completed a proof-of-concept (PoC) connecting XDC with R3’s Corda platform via a Corda Bridge provided by IMPEL GLOBAL, INC. Fiat payments from business-to-business transactions settled through that bridge using XDC, giving corporate users a hybrid model that keeps transaction data private while recording value transfers on the public chain. By December 2024, the venture extended the work to used automobile export procedures, partnering with SS Trading to digitize the paper-heavy export documentation and trade finance process for cross-border vehicle shipments.

Payments and the RLUSD Launch

SBI Holdings’ relationship with Ripple dates to 2016, when the two established SBI Ripple Asia as a joint venture for XRP-based remittances across Asia-Pacific. The conglomerate now holds roughly 9% of Ripple, the largest external equity stake in the company. Its remittance arm became Japan’s first On-Demand Liquidity (ODL) provider in 2021, using XRP as a bridge currency for payment corridors to the Philippines, Vietnam, and Indonesia. Japan now accounts for more than half of Ripple’s worldwide ODL volume.

On March 31, 2026, SBI VC Trade began distributing RLUSD in Japan, the first regulated distribution of Ripple’s dollar-backed stablecoin anywhere in Asia. RLUSD is backed 1:1 by U.S. dollar deposits, short-term U.S. Treasuries, and cash equivalents, with monthly reserve attestations from Deloitte. February 2026 figures showed $1.568 billion in reserves against 1.49 billion tokens in circulation.

Japanese retail investors had already built a significant XRP position before any of that. Between July 2024 and June 2025, $21.7 billion flowed into XRP through centralized exchanges in Japan, more than four times what moved into Bitcoin over the same period, under a crypto gains tax that reached 55%. SBI Holdings filed applications with Japan’s Financial Services Agency (FSA) in August 2025 for a spot Bitcoin and XRP exchange-traded fund on the Tokyo Stock Exchange, targeting $32 billion in assets under management within three years.

Shipping Lines, Carbon Credits, and the Algorand Thread

ITOCHU Corporation and Mitsui O.S.K. Lines signed a memorandum of strategic partnership in January 2026 to trade Environmental Attribute Certificates (EACs), tradeable credits representing verified emissions reductions in the transport sector. Both companies used 123Carbon, a Dutch environmental technology firm whose platform runs on the Algorand blockchain, to execute Japan’s first cross-sector EAC trade.

The transaction structure reflects the logistics each company needed to address. MOL purchased EACs from ITOCHU to offset air transport emissions from its employees’ frequent business travel, while ITOCHU acquired EACs from MOL to cover maritime freight emissions. Both needed the certificates traceable across complex global supply chains without depending on any single counterparty’s internal record-keeping.

“Collaboration across the entire transportation supply chain is essential to achieving net-zero,” MOL said in its announcement, describing the partnership as “a concrete example of stakeholder co-creation.”

Algorand’s January 2026 network report confirmed the MOL-ITOCHU EAC partnership as part of a quarter in which on-chain stablecoin transaction volume on the network surged 91.6% from December 2025 figures. The network’s design suits this kind of institutional documentation: Algorand processes more than 30,000 transactions per second, settles with instant finality, and runs on a Pure Proof-of-Stake (PPoS) consensus mechanism that gives it a carbon-neutral footprint. When the certificates being recorded are emissions reductions claims, the audit trail’s integrity depends on the infrastructure carrying it.

The global carbon offsets and credits market is valued above $400 billion, with some projections reaching $1.6 trillion by 2028. Japan’s Scope 3 emissions commitments, which cover a company’s supply chain emissions rather than its own direct output, create a structural institutional demand for on-chain documentation of exactly this kind.

The Regulatory Architecture

Japan’s enterprise DLT deployments rest on nearly a decade of regulatory groundwork. The country built a framework specific enough for institutions to plan production deployments around it, not just run pilots.

• Payment Services Act (2017): Japan’s first legislation classifying cryptoassets as legally recognized property, establishing custody, transaction, and compliance standards for licensed institutions.
• LDP on-chain finance project team (March 2025): Japan’s Liberal Democratic Party (LDP) established the Next-Generation AI and On-Chain Finance Vision Project Team, focused on frameworks for on-chain financial systems, supply chain finance, and carbon credit tracking.
• FSA revised framework (late 2025): Japan’s Financial Services Agency completed updated crypto asset regulations, creating one of the world’s clearest legal environments for stablecoin issuance, exchange licensing, and institutional participation in digital asset markets.
• Top three banks stablecoin project (late 2025): the Japanese government backed a consortium of Japan’s three largest commercial banks to issue stablecoins for payments and settlements, under FSA oversight.
• FIEA amendment (April 10, 2026): Japan’s cabinet approved amendments to the Financial Instruments and Exchange Act (FIEA), Japan’s securities law framework, reclassifying 105 cryptoassets as financial instruments. Pension funds, insurance companies, and asset managers gain a regulatory path to hold crypto-backed products through the same compliance channels they use for Japanese equities.
• Crypto tax reform: Japan is replacing the progressive crypto gains tax, which reached 55%, with a flat 20% rate matching equities, including a three-year loss carryforward. Implementation is targeted for late 2026 or early 2027.

Four Protocols, One Template

The four enterprise partnerships share a profile that separates them from the bulk of blockchain activity in the region. Each addresses a specific institutional friction at the intersection of regulated finance and Japan’s corporate economy. None requires retail token adoption or speculative volume to function.

Japan’s tokenized real-world asset market had reached $2.8 billion by early 2026, with projections toward $6-7 billion by year-end, according to data cited at the XRP Tokyo 2026 conference held in April. That capital comes from the kind of structured institutional deployment that starts with a 300-million-yen joint venture and ends with a completed proof-of-concept for used automobile export finance. The pattern across the four partnerships, a regulated Japanese corporate counterpart, a protocol chosen for a specific operational friction, and an institutional framework to work within, is what separates enterprise DLT from the token speculation cycle that runs alongside it.

The FIEA implementation arrives in fiscal 2027; by then, the production infrastructure for four of those reclassified assets will have been operating in Japan for years.
