Mints Introduces AI-Driven Automation for Legal Document Management, Reducing Administrative Burden
Mints, a Japanese fintech company specializing in AI solutions for legal and financial sectors, has launched an automated system to handle evidence number processing, enabling legal professionals to redirect time from administrative tasks to core legal work, according to a recent company announcement.
How Mints’ Automation Works
The platform, part of Mints’ broader “Lawyer’s Desk” suite, uses machine learning to categorize, tag, and organize legal documents, eliminating manual entry of evidence numbers. This reduces the time lawyers spend on document sorting by up to 70%, as reported by a pilot study conducted with 15 law firms in Tokyo and Osaka. “This technology allows us to focus on client strategy rather than paperwork,” said a partner at one participating firm, who requested anonymity.
The system integrates with existing legal software, automatically extracting metadata from scanned files and cross-referencing it with case databases. Mints’ CEO, Hiroshi Tanaka, highlighted that the tool complies with Japan’s strict data privacy laws, ensuring sensitive client information remains secure.
Impact on Legal Efficiency
Legal professionals in Japan face significant administrative workloads, with a 2023 survey by the Japan Federation of Bar Associations revealing that 62% of lawyers spend over 20 hours weekly on non-legal tasks. Mints’ solution aims to address this gap, offering a scalable alternative to traditional document management systems.
Early adopters report faster case preparation and improved accuracy. A Tokyo-based litigation firm noted a 40% reduction in document-related errors within three months of implementation. “The AI’s ability to flag inconsistencies in evidence numbering has been invaluable,” said a senior associate at the firm.
Broader Implications for Legal Tech
The introduction of Mints’ tool reflects a growing trend in legal technology, where AI is increasingly used to streamline back-office operations. Competitors like LegalSifter in the U.S. and DocuSail in the U.K. have also developed similar tools, though Mints’ focus on Japanese regulatory compliance sets it apart.

Industry analysts suggest that such automation could reshape the legal workforce. “As routine tasks become automated, lawyers will need to upskill in areas like data analysis and AI collaboration,” said Dr. Aiko Sato, a legal tech researcher at Waseda University. “This is a shift we’ve seen in other industries, and law is no exception.”
Challenges and Adoption Rates
Despite its benefits, the technology faces adoption hurdles. Smaller law firms, particularly in rural areas, cite high initial costs and a learning curve as barriers. Mints has responded by offering tiered pricing plans and free training modules, according to its website.

Additionally, some legal professionals remain skeptical about relying on AI for critical tasks. “While the technology is promising, human oversight is still essential,” cautioned a prominent Tokyo attorney. “We can’t fully trust an algorithm to handle matters as nuanced as legal evidence.”
Looking Ahead
Mints plans to expand its AI capabilities beyond document management, with a roadmap including contract analysis and real-time compliance checks. The company’s next major update, slated for 2024, will incorporate natural language processing to summarize case documents, according to a press release.
As AI continues to permeate the legal sector, tools like Mints’ could redefine efficiency benchmarks. However, their success will depend on balancing technological innovation with the human elements that remain central to legal practice.
