Tokyo, September 27, 2019 Sekisui House, Ltd. (TSE: 1928, Sekisui House), KDDI Corporation (TSE: 9433, KDDI), and Hitachi, Ltd. (TSE: 6501 Hitachi) announced that they have started joint trials to improve real estate rental contract process through blockchain technology based inter-enterprise information sharing [
1], with other companies newly participating in the project, further accelerating co-creation for commercialization. In the joint trials, investigation will be started to simplify fire/earthquake insurance and energy services contracts required at the time of changing address with the participation of Sompo Japan Nipponkoa Insurance Inc. (TSE: 8630, Sompo Japan Nipponkoa), Tokio Marine Holdings, Inc. (TSE: 8766, Tokio Marine), Mitsui Sumitomo Insurance Co., Ltd. (TSE: 8752, Mitsui Sumitomo Insurance), Osaka Gas Co., Ltd. (TSE: 9532, Osaka Gas), and Toho Gas Co., Ltd. (TSE: 9533, Toho Gas) as new members.
Background The super-smart society [
2] envisioned by the Japanese Government (Society 5.0 [
3]) aims to create new value for users and improve user convenience through digital technologies and data. In order to realize the super-smart society, a platform for sharing information among enterprises and aggregating mutual services are required.
Since April 2019, Sekisui House, KDDI, and Hitachi have conducted their initiative trial to establish an inter-enterprise neutral information-sharing platform using blockchain technology, which has immutability and high-availability [
4] features and is considered to be suitable for secure information sharing among multiple enterprises.
This trial has verified the business model and serviceability of the one-stop service, such as a reduction in time spent by users through pre-filling the current address and telephone number when applying for preview of rental properties using personal ID verification information [
5] held by Sekisui House and KDDI.
Description of this initiative As the second verification, sharing the personal ID verification information of those who shifted from the phase of previewing properties to the phase of contracting, with their consent, to simplify earthquake insurance and energy infrastructure service contract procedures will be investigated in collaboration with Sompo Japan Nipponkoa, Tokio Marine, Mitsui Sumitomo Insurance, Osaka Gas and Toho Gas.
This will verify real estate rental contracts in the inter-enterprise information-sharing platform, such as simplifying various procedures for new service contract start of use, suspension, cancellation, and change of address. At the same time, in order to realize an efficient property preview without the presence of a real estate management company, it will verify the issuing of the smart lock [
6] based on the personal ID verification information of the inter-enterprise information-sharing platform and viewing permission.
Future plans Moving forward, Sekisui House, KDDI, and Hitachi will further advance collaborative creation together with Sompo Japan Nipponkoa, Tokio Marine, Mitsui Sumitomo Insurance, Osaka Gas, and Toho Gas, aiming at commercialization of the inter-enterprise information-sharing platform for real estate rental in 2020. The companies will enhance their initiatives through the standardization of online procedures for real estate rental contracts using knowhow obtained in the trials through use cases in real estate rental and will collaboratively create various services using the inter-enterprise information-sharing platform.
Moreover, the companies will widely call for companies and groups to participate in this project for application of the platform in the fields of financing and municipal administration, aiming at establishment of a company consortium in 2020 for the purpose of realizing an ecosystem useful for both customers and enterprises, and accelerating open innovation. Through the shared use of information held by each company and collected and shared on the platform with the consent of each customer, companies will create new value for users realized through the combination of data from different industries and the expansion of the scope of the industries through the bulk conclusion of contracts and one-stop procedures, they will thus realize further convenience across the borders of industries.
