Hitachi Launches "Digital Asset AML Platform": Cross-Industry AML That Shares Risk Signals, Not Personal Attributes, Reaches Commercial Stage

What has launched

On October 5, 2026, Hitachi announced that on October 1 it had begun offering "Digital Asset AML Platform," an AML monitoring service for transactions in crypto-assets, stablecoins and other digital assets. Target customers are financial institutions and crypto-asset businesses. The core is risk-information sharing between operators: shared fields are limited to wallet addresses, transaction hashes, risk categories and detection reasons, and personal attribute data is not shared. There are three functions: post-transaction monitoring that continuously tracks changes in risk after a transaction, online real-time assessment of a counterparty address before a transfer, and token monitoring that checks the circulation risk of stablecoins and similar tokens after issuance. These layer AI and machine-learning analysis of transaction behavior on top of external blockchain analytics, sanctions and crime-related information, and online fraud data. Supported chains, tokens and pricing are not disclosed and depend on contract terms.

Two rounds of testing and the FSA's assessment

The service went through two proofs of concept. The first, from February to April 2025, involved Hitachi and 12 companies, including Nomura Holdings, Hokkoku Bank, bitbank, JPYC, Chainalysis Japan and NEC. The second, from March to May 2026, was Case No. 13 under the FSA's FinTech PoC Hub and involved 17 companies, among them Aozora Bank, GMO Coin, Rakuten Wallet, DCP and Japan Blockchain Infrastructure, plus three undisclosed firms. The FSA published results on July 24. It acknowledged that cross-operator sharing may surface risk signals that a single firm struggles to see, that combining list-matching with machine learning also detected signals outside known lists, and that all three functions were operationally feasible. It also stated plainly that alerts alone are not sufficient grounds for suspicious transaction reports, transaction restrictions or freezes, and that supplementary investigation of fund flows and related addresses is needed.

The privacy-law framework

The results also set out a legal framework. Based on advice from the Personal Information Protection Commission, the FSA stated that consent-based third-party provision only requires consent to exist at the time of provision, and that when addresses that constitute personal data are provided under the asset-protection exception (Article 27(1)(ii) of the Act on the Protection of Personal Information), necessity must be judged case by case by weighing the harm to the individual against the need for provision. To prevent unjust harm from false positives, it also called for data accuracy and timeliness, correction and deletion procedures, and explainable alert rationales, including for machine-learning models. Hitachi's decision to exclude attribute data from sharing reads as a design answer to these issues.

Why joint AML, and why now

The backdrop is the shift of illicit funds into stablecoins. Chainalysis estimates that illicit addresses received at least $154 billion in 2025 and that 84% of illicit transaction volume was in stablecoins. FATF's July 2026 targeted update on virtual assets likewise notes that most identified on-chain illicit activity now involves stablecoins. According to Hitachi, a revision of Cabinet Office ordinances on stablecoins took effect in Japan in June 2026, and full-scale issuance of trust-type stablecoins began. Overseas, TRM Labs launched Beacon Network in August 2025 as a real-time alert network linking exchanges and issuers, and the Monetary Authority of Singapore put COSMIC, an inter-bank platform for sharing customer risk information, into operation in April 2024 alongside a legislative amendment. In Japan's banking sector, the Money Laundering Countermeasures Joint Organization established by the Japanese Bankers Association is pooling AI-based alert scoring. Hitachi's initiative carries that trend into digital assets.

What to watch next

As a next step, Hitachi says it will work with participating firms to develop an "AML Joint Center" concept that would investigate high-risk transactions on individual commission from operators, but no timeline or structure has been given. Effectiveness will depend on how widely operators participate, how sharing rules and data governance mature, and how clearly responsibility is allocated while final decisions remain with each firm.

[Business Development Insights]

1. For crypto exchanges and banks handling electronic payment instruments, AML that is self-contained within in-house data and a single vendor's screening is losing explanatory power. Now that the FSA has positively characterized joint sharing as "mutual assistance," whether to join a sharing network becomes a supervisory question. Joining requires first completing legal review and a privacy impact assessment as a data provider, and putting in place internal rules and contracts covering sharing scope, correction and deletion, and complaint handling, which takes months of preparation.
2. For stablecoin issuers and trust banks, post-issuance circulation monitoring is becoming part of issuer responsibility. The FSA's PoC explicitly included a function for issuers to trace misused tokens and freeze or burn them. Since the FSA also stated that freeze decisions cannot rest on alerts alone, building monitoring, investigation, freeze execution and remediation of wrongful freezes into a single operational flow at the scheme-design stage becomes a differentiator.
3. As joint AML spreads, value shifts from detection itself to adjacent functions such as investigation on commission, data governance and assurance of explainability. Responsibility boundaries between a joint center, analytics vendors and individual operators are not yet settled, leaving practical gaps around liability when a false positive halts a customer's transaction and around how corrections to shared signals are processed. Compliance orchestration and audit support that fill these gaps represent business opportunities for both financial institutions and service providers.
