Hifumi's Pioneering Partnership with JPX on J-LENS

Hifumi Co., Ltd., a technology company specializing in AI solutions tailored for finance, securities, and accounting, has recently made headlines by providing expert generative AI support for the development of the JPX Research Institute's new AI disclosure search service, J-LENS (beta version). The service was unveiled during a release event held at WeWork Akasaka Green Cross on December 9, 2025, where Hifumi's representative, Taku Hatada, participated in an expert talk and panel discussion to share insights about the partnership's significance and the technology's contribution.

Overview of J-LENS

J-LENS stands out as an innovative natural language search service utilizing AI, created by the JPX Research Institute. Unlike traditional keyword searches that often fail to capture nuances like variations in wording, negations, numerical conditions, and ambiguous expressions, J-LENS enables users to efficiently and accurately sift through an extensive database of disclosure information from Tokyo Stock Exchange-listed companies. This technology marks a significant leap forward in the accessibility of critical financial data.

Key Features of J-LENS (Beta Version)

• - Advanced AI Support: Hifumi's cutting-edge generative AI technology has significantly improved the accuracy of the core vector search engine, specifically tuned for the intricacies of financial terminology and expressions found in disclosure documents.
• - Domain Expertise: Hatada leveraged his considerable expertise in finance and securities, allowing a deep understanding of document structures. This knowledge helped streamline the extraction of precise information without incurring unnecessary costs.
• - Tailored Implementation Support: Hifumi provided the necessary deliverables formatted for JPX Research Institute's environment, ensuring that engineers could easily integrate and utilize the new technologies within just two days.

Statements from Both Companies

Atsushi Yamato, Executive Officer at JPX Research Institute

“Support from Hifumi’s generative AI technology has been a driving force in the development of J-LENS. The combination of domain knowledge in finance and state-of-the-art AI capabilities allowed us to accelerate what would have otherwise taken years of internal validation down to just a few months. We’re thrilled that this success stemmed from our encounter in the WeWork community.”

Taku Hatada, CEO of Hifumi Co., Ltd.

“It is an honor to have contributed to developing such a vital service that supports the infrastructure of financial markets in collaboration with JPX Research Institute. I was particularly impressed by the organization's flexibility, which fostered a culture of adaptation and iterative development, enabling us to fully leverage our capabilities.”

Event Highlights

During his expert talk, Hatada discussed the importance of viewing development through the lens of both 'customers' and 'end customers.' He emphasized that the collaboration between the developers and the contracting agency, JPX Research Institute, to enhance value for investors was critical for effectively leveraging AI technology.

Furthermore, he articulated the analogy of generative AI as akin to a sushi chef and data as the fish used—reflecting the meticulous effort required to prepare data to allow AI to perform optimally. He also pointed out that as AI models become universally accessible, the unique preparation of proprietary data will define competitive advantages.

Hatada also recognized the strength of the WeWork community, emphasizing how shared environments fostered swift and effective dialogues, highlighting the community's role as a backbone of trust that supports innovation.

Backstage of Collaboration

This partnership, which blossomed from a WeWork community event focusing on workplace reform, was facilitated when Hatada recognized the potential to solve existing challenges JPX Research Institute faced with non-structured data extraction during a presentation. This spontaneous demonstration ultimately paved the way for the development of J-LENS.

Secrets of Fast-Track Development

Yamato remarked on the importance of internal structuring to increase experimentation, stating that initial development only took around five months. Hatada echoed this sentiment, noting rapid contract exchanges that contributed to an unprecedented pace of execution.

Community leader and CEO of WeWork, Kumagai, elaborated that the speed of innovation hinges not only on technical prowess but significantly on the 'speed of trust-building.' The essence of being part of a community allowed for this acceleration, highlighting the importance of fostering relationships in achieving business agility.

Future Prospects

Hifumi envisions leveraging this cooperation with JPX Research Institute to explore further data analysis projects within the securities market. They aim to enhance the quality of information disclosure for listed companies while improving investor access to critical data, ultimately contributing to the growth of Japanese firms and the economy.

With a dedicated focus on streamlining operations through generative AI, Hifumi plans to offer AI review services for securities reports and comprehensive consulting for timely disclosures, ensuring robust communication between companies and investors.

Through its pioneering efforts in AI applications for the finance, securities, and accounting sectors, Hifumi is committed to enhancing productivity and strengthening the competitive edge of Japanese corporations.
