Mitsui Fudosan Co., Ltd.
Tokyo, Japan, July 1, 2021 – Mitsui Fudosan Co., Ltd., a leading global real estate company headquartered in Tokyo, has conducted a trial test at Kashiwa-no-ha Smart City together with PI-CRYSTAL, INC. to continually measure temperature and vibration during long-distance distribution processes using organic semiconductor film devices*, a technology developed for the first time in Japan by the University of Tokyo. This resulted in the successful development of a tracing system (hereinafter, “the system”) that makes it possible to store various types of information, such as temperature and vibration, on a single thin, lightweight film device and continually obtain data, while sharing the data on the cloud.
With this system, data related to temperature and vibration of cargo can be continually measured during long-distance distribution processes, supporting good distribution practices (GDP) in the medical field and in drug transportation, including COVID-19 vaccines, and HACCP/ISO 22000 compliance for perishable goods such as fresh fish. Moreover, this beneficial data could be used to guarantee logistics quality or propose improvements to quality, which must be further enhanced in the future. The system will further realize safe and secure distribution services in various fields such as chemicals and overseas distribution.

Concept for an ecofriendly, low-cost reusable distribution tracing system with long-lasting film devices using organic semiconductor sensors
This trial test utilized the Innovation Field KASHIWA-NO-HA framework, a verification platform that uses Kashiwa-no-ha Smart City as its setting, and was carried out through collaboration and cooperation with multiple locations and businesses within Kashiwa-no-ha Smart City. Mitsui Fudosan will continue to carry out verification projects and conduct studies for utilizing the organic semiconductor film device developed by PI-CRYSTAL in many types of assets in the Kashiwa-no-ha area. In this way, the Company will aim to establish it as a service and expand it nationwide. Through the initiative of this trial test, Mitsui Fudosan aims to implement safe and secure distribution services in the Kashiwa-no-ha area. We are also conducting studies regarding smart development of the entire neighborhood by implementing this organic semiconductor film device technology in other assets.
■ Kashiwanoha Campus Area
Located approx. 30 minutes from central Tokyo, Kashiwa-no-ha Smart City offers tremendous accessibility, and is also an area of accumulated knowledge where the nation’s top research institutes such as The University of Tokyo and Chiba University are concentrated within a 2 km radius of Kashiwanoha-campus Station. Kashiwa-no-ha Smart City is being built through a private-public-academic collaboration, and there is proactive engagement in demonstration projects using technology from startups and universities.
Additionally, Innovation Field KASHIWA-NO-HA, a testing platform serving as a receptor for all experimental projects staged in the town of Kashiwa-no-ha, was launched in February 2019. It is conducting various tests and experiments using cutting-edge technologies.
