Thomson Reuters Brings Fiduciary-Grade AITM Standards to Japanese Legal Research and Trade Compliance

Thomson Reuters (Nasdaq/TSX:TRI), a global content and technology company, today announced two AI-powered enhancements for Japanese professionals, adding new AI capabilities to ONESOURCE Global Trade and Westlaw Japan. These capabilities are built on Thomson Reuters' CoCounsel AI technology and grounded in trusted Japanese content, enabling trade, compliance, and legal teams to receive answers with citations and links to authoritative sources.

This solution is built on Thomson Reuters' Fiduciary-Grade AITM. As AI becomes more deeply embedded in regulatory workflows, Fiduciary-Grade AITM is designed for practitioners who have a professional duty of care and are subject to regulatory oversight. It is designed to be grounded in authoritative, domain-specific content, protected by stringent privacy and security, and to reflect the insights of domain experts to provide verifiable and transparent answers.

“Trust in professionals has always been built on trusted standards and accountability. The same thinking is needed for AI tools that professionals use every day,” said Kenito Miura, President and Representative Director of Thomson Reuters Japan. “Whether it’s a judicial authority or an inquiry from customs, Japanese professionals are required to explain the basis for their decisions. AI tools must meet the same standard. These enhancements will allow legal and trade management teams to spend more time on the decisions that truly matter, while ensuring the traceability and accountability required for advanced professional work.”

The announcement comes as the role of professionals operating under regulation is rapidly changing. A study, “The Future of Professionals 2026,” found that 74% of professionals globally use AI tools multiple times per week. However, 41% do not have access to tools built to the standards required for their professional work, and more than a third of professionals use AI tools that are not approved by their organizations. The question is no longer whether AI can generate an answer, but whether professionals can verify and responsibly use that answer.

ONESOURCE Global Trade AI Enhancements

The new AI capabilities in the global trade space leverage Thomson Reuters’ proprietary content, including Harmonized System tariff codes, dual-use item lists, denied party and sanctions lists, and trade agreement content, maintained 365 days a year for more than 210 countries and territories.

· ONESOURCE Global Classification powered by CoCounsel is designed to assist with HS code classification. It provides classification suggestions and their rationale based on product descriptions, specifications, uses, materials, and past classification records. Trade professionals will review the evidence before making a final determination.

· ONESOURCE Global Trade Research powered by CoCounsel assists trade compliance professionals with their research tasks. It provides answers linked to sources across relevant jurisdictions through an AI-powered chat interface in Japanese for customs duties, regulations, notices, government documents, and import/export requirements and related information.

The AI capabilities on ONESOURCE Global Trade are expected to be generally available to customers in Japan in Q4 2026.

Westlaw Japan New AI Innovations

For legal professionals, new features on the Westlaw Japan platform will transform legal research from traditional keyword searches to AI-powered, natural language conversational research. Building on Westlaw Japan AI-Assisted Research, which launched in April 2026, Thomson Reuters is delivering further AI capabilities to customers this month.

· A suite of AI research experiences grounded in trusted professional content

Westlaw Japan’s generative AI supports legal professionals through a single workflow, from question to verifiable answer. This experience is built exclusively on Thomson Reuters’ trusted legal content, not the open web. The enhanced, two-stage research experience includes:

o Smart Search: AI interprets the user’s intent and automatically suggests relevant legal concepts, enabling users to find more comprehensive and accurate relevant sources.

o Legal-Specific AI: Professionals can ask questions in natural language and receive structured answers generated exclusively from Westlaw Japan’s trusted sources, including statutes, case law, key legal publications, and commentary and law journals, with every answer verifiable by citation.

o Modern UI/UX: Built on the latest Thomson Reuters design system, it provides an intuitive user experience for legal professionals and non-legal business users alike. It supports PC, mobile, and tablet devices, enabling multi-device access and flexible working to create a research environment that fits how professionals actually work.

The announcement was made at SYNERGY Tokyo, Thomson Reuters’ premier customer conference for professionals in legal, tax, trade, and compliance.
