Legalscape Inc. (Headquarters: Bunkyo-ku, Tokyo; President and CEO: Itsuki Yagita; hereinafter "Legalscape") announces that the number of recorded books on its legal research platform "Legalscape" has exceeded 4,500.
Legalscape achieved the No. 1 position in the industry for the number of recorded books in legal research tools in October 2025 (*). In addition, the total number of legal information items, including laws and regulations and public comments, has exceeded 44,000, achieving further expansion as one of Japan's largest legal databases.
■ Background: Achieving both "comprehensiveness" and "speed" in legal research
In legal practice, the comprehensiveness and accuracy of underlying information are indispensable. However, the task of extracting necessary information from vast paper-based specialized books and diverse administrative documents places a significant burden on legal professionals.
To solve these challenges, Legalscape has accelerated the digital recording of books through partnerships with over 40 publishers. After surpassing 4,000 books in August 2025 and achieving "No. 1 in book count (*)" in October 2025, it has continued to prioritize adding the latest commentaries and specialized books directly relevant to practice, which were highly requested by practitioners. By combining high reliability and overwhelming information volume with AI technology, Legalscape supports the efficiency of research operations.
