One in Five Lawyers in Osaka Uses the Legal Research AI "Legalscape" — Adoption Accelerates Across the Kansai Region

Legalscape Inc. (Headquarters: Bunkyo-ku, Tokyo; President and CEO: Itsuki Yagita; hereinafter "Legalscape") announced that one in every five lawyers registered with the Osaka Bar Association is now using its legal research AI platform, "Legalscape." (※1)

Having already achieved adoption by approximately one in three lawyers in Tokyo, the platform's momentum is now spreading to the Kansai region. Adoption is accelerating in Osaka—the city with the largest concentration of legal professionals in Kansai—demonstrating steady nationwide penetration among legal practitioners.

Background: Inefficiency in Legal Research Has Long Been a Challenge in Legal Practice

Legal research—searching statutes, court rulings, and academic literature—is a fundamental task in legal practice. The need to cross-reference multiple databases and printed materials has long consumed significant time, posing a persistent challenge for legal professionals in Osaka.

To address this issue, Legalscape launched its legal research AI platform "Legalscape" in June 2021, creating a unified environment for searching and viewing statutes, case law, books, and guidelines. In September 2023, the company became the first in Japan to introduce an AI research function combining generative AI with its proprietary natural language processing technology. (※2)

Details of Usage: One in Five Osaka Bar-Affiliated Lawyers Now Using Legalscape—Adoption Gains Traction Across Kansai

Currently, one in five lawyers registered with the Osaka Bar Association uses "Legalscape." Following its success in Tokyo, adoption is rapidly expanding across the Kansai region. The platform is now widely used across diverse legal practice settings—from large and mid-sized law firms with various specializations to solo practitioners handling local civil legal matters.

Key factors driving adoption include:

Industry-leading content volume (※3): Covers over 4,500 legal books, case law, statutes, and guidelines—the largest collection in the industry.

AI Research Function: Combines generative AI with proprietary natural language processing to instantly summarize and present research findings.

Cross-domain unified search: Enables cross-database search of statutes, case law, books, and guidelines on a single platform, with one-click navigation to source materials.

Future Initiatives: Accelerating Nationwide Expansion Based on Kansai Adoption

Legalscape will continue expanding its service to a broad range of legal professionals—including lawyers, corporate legal departments, judicial scriveners, and social insurance labor consultants—while further enhancing its AI research capabilities. Building on its proven adoption in Tokyo and Osaka—Japan’s two largest legal markets—the company aims to accelerate nationwide rollout and create an environment where legal professionals in every region can access accurate legal information.
