1. Blockchain-based Inter-enterprise Information Sharing of Real Estate Rental Contracts
With the aim of delivering enhanced new benefits and enhanced convenience for users, the Society 5.0 vision being promoted by the Japanese government calls for the establishment of platforms that utilize digital technology and data to enable the coordination of services and for data from one industry to be complemented by that from another through the sharing of information between companies.
Sekisui House, Ltd., KDDI Corporation, and Hitachi have since April 2019 been working on building an information sharing platform that operates as an intermediary between companies. The platform uses blockchain technology that, because of its characteristics of high availability and being difficult to tamper with, is well suited to the secure sharing of information between companies.
Working in partnership with Sompo Japan Nipponkoa Insurance Inc., Tokio Marine Holdings, Inc., Mitsui Sumitomo Insurance Company, Ltd., Osaka Gas Co., Ltd., and Toho Gas Co., Ltd., who joined the project in October 2019, a study was launched into lease contract simplification involving an inter-enterprise information sharing platform that includes simplifying such procedures as applications for new products or services; the commencement, suspension, or termination of such arrangements; and the notification of changes of address by using the identity verification information that has been passed on from preliminary examination (vetting) to the signing of the lease contract and linking it (with the consent of the person concerned) to administrative procedures for fire and earthquake insurance and energy infrastructure.
Further collaborative creation between the companies involved is planned in preparation for the inter-enterprise information sharing platform for real estate leasing entering commercial operation in 2020. The aim is to establish a consortium of companies in 2020 with the aim of recruiting further companies and organizations into the scheme to create an ecosystem that has value for both ordinary consumers and companies and to accelerate open innovation.
