Zenhoren Co., Ltd.
IBM Japan, Ltd.
Zenhoren Co., Ltd. (Headquarters: Naha City, Okinawa Prefecture / Shinjuku Ward, Tokyo; Representative Director, Chairman and President: Hidehiko Ibaraki; hereinafter "Zenhoren"), a rent guarantee company, and IBM Japan, Ltd. (Headquarters: Minato Ward, Tokyo; Representative Director and President: Akio Yamaguchi; hereinafter "IBM Japan") have formed an AI partnership to accelerate the utilization of AI and data, aiming to advance guarantee services in the real estate industry.
Established in 2001, Zenhoren is a member of the Mitsubishi UFJ Financial Group, upholding the corporate philosophy of "QUALITY FOR THE FUTURE: Towards New Value, Towards a New Future." As the industry's largest rent guarantee company, it provides services to real estate management companies, owners, and tenants nationwide, offering comprehensive support from lease application screening to in-residence guarantees and move-out procedures, thereby providing security and trust to Japan's rental market.
Zenhoren actively promotes the use of digital technology to enhance the quality of operations for real estate management companies, owners, and tenants, and to strengthen the reliability of its guarantee services. Meanwhile, in recent years, due to changes in the social environment and industrial structure, the needs surrounding the guarantee business in the real estate industry have changed significantly. In particular, there is a growing social demand for rapid service provision and for demonstrating the validity of guarantee results in an explainable manner, especially in guarantee processes including screening. To meet these needs, there is a demand for a shift from conventional standardized guarantee provision models to guarantee processes based on data utilization and advanced risk assessment.
Therefore, Zenhoren has formed an AI partnership with IBM Japan, which has extensive experience in advanced technologies such as AI and consulting, to advance guarantee services using AI. Through this partnership, the two companies will co-create transformations in the following three areas:
1. Advancement of Guarantee Processes through the Construction of a Seamless Integrated AI Platform
By developing a seamless integrated AI platform where multiple AI agents can collaborate with data and APIs while sharing roles, the companies aim to advance complex guarantee processes. This is expected to shorten the period until guarantee certification and standardize screening content.
2. Strengthening Services by Establishing a New Guarantee Model through AI-Human Co-creation
AI will be utilized for analyzing credit information related to personal financial transactions for credit and loan contracts and applications in guarantee services. While AI analysis will shorten screening times and standardize and ensure fairness of screening criteria, the final decision will be made by humans, thereby building a guarantee process through AI-human co-creation. This will promote the establishment of a new guarantee model that ensures and explains the validity of screening results, thereby strengthening services that customers can use with peace of mind.
3. Improving Development Productivity through the Utilization of Specification-Driven Development
In Zenhoren's guarantee services, including screening operations, the companies will leverage IBM Bob, an AI agent-driven enterprise development support partner, to advance system development, such as online systems for real estate companies to improve operational efficiency. AI will assist in processes such as organizing requirements definitions during screening, source code creation, and test case generation, thereby promoting improved development productivity and standardization of quality, and driving structural transformation of guarantee services.
Through this partnership, Zenhoren and IBM Japan aim to accelerate the utilization of AI and data, and by advancing guarantee services in the real estate industry, they seek to present a new standard for AI-powered guarantee services. This will enable the provision of faster, more reliable, and reassuring services to all customers who use Zenhoren.
