Digital Transformation in Law: Legal Corp Launches “Mamoru” Lawyer’s Desk for Seamless Document Management
The legal sector, long characterized by mountains of paper and labor-intensive manual filing, is undergoing a significant shift toward cloud-integrated workflows. 株式会社リーガル (Legal Corp), a veteran in developing specialized software for legal professionals, has announced the launch of “Mamoru” Lawyer’s Desk, a cloud-based document management service designed to bridge the gap between traditional office practice and modern remote work requirements.
Scheduled for release on May 29, 2026, the service aims to solve the perennial legal industry challenge of “time lost searching for documents” by centralizing fragmented files into a searchable, intelligent library.
Transforming Law Office Productivity
For many law firms, the daily workflow involves juggling Word documents, Excel spreadsheets, PDFs, and physical paper files. This fragmentation often forces attorneys to return to the office simply to access physical files or specific local-only data. “Mamoru” Lawyer’s Desk addresses this by creating a virtual “always-on” desktop environment.

Key features of the new platform include:
- Intelligent OCR & Full-Text Search: By employing AI-driven optical character recognition, the system converts scanned documents and existing files into a searchable database, allowing attorneys to retrieve specific case information via keywords instantly.
- Cloud-Local Integration: The service allows users to open and edit files directly from the cloud using local applications. Changes are automatically synced, eliminating the tedious manual download-and-upload cycle.
- Evidence Management for mints: The platform includes dedicated tools for the mints system (the Japanese civil litigation electronic submission platform), including automated evidence numbering and PDF annotation features specifically designed for court submissions.
- Mobile Integration: Attorneys can use smartphones to scan evidence, which is then automatically sorted into the correct case folders, significantly reducing administrative overhead.
Security and Compliance in the Legal Sector
Data privacy is the cornerstone of any legal practice. Legal Corp has addressed these concerns by ensuring that all data processed through the service is stored on servers located within Japan. The company maintains a strict policy regarding the use of processed data: once the AI-OCR analysis is complete, the data is automatically deleted and is never used for external AI training, model development, or third-party data sharing.
Key Takeaways for Legal Professionals
The transition to a cloud-first legal environment is no longer just about convenience; it is about maintaining competitiveness. For firms using the “Mamoru” (護) system, this update provides a direct path to higher billable efficiency.

Pricing and Availability
The service is designed to be accessible for firms of varying sizes. The base subscription starts at 2,420 yen per month (tax included), which includes one account and 50GB of storage. Scalability is built-in, with additional storage available at 660 yen per 10GB and extra accounts at 990 yen per month. The service is available to existing users of the “Mamoru” permanent license and “First” annual subscription plans.

The Future of Legal Practice
As the Japanese judicial system continues its push toward increased digitization, tools like “Mamoru” Lawyer’s Desk represent a necessary evolution. By offloading the “grunt work” of document management to automated, cloud-based systems, attorneys can reclaim time previously lost to logistics. This shift allows legal professionals to focus on what matters most: the nuanced strategy and advocacy required to represent their clients effectively.
