  • 2 Environmental sensing: Using sensors to obtain data such as humidity, temperature, volatile organic compounds (VOCs), PM2.5, and CO2


  • Provision of health services and advice utilizing wide-ranging data (full-fledged operation in FY2020)
    Making use of the member network of ASHITA, a participation-style health center located in front of the station where people gather and data can be easily collected, efficiently collect data such as activity level and amount of sleep via wearable devices*3 and sheet-type pressure sensors*4, and use this data to provide detailed health services and advice targeting individuals. Take collected nursing care and medical receipt data*5 as well as activity level and sleep amount data, etc. to identify special characteristics on lifestyle habits and illness history that can cause people to need care, and encourage participation in work, volunteer activities and hobby groups that can lengthen healthy lifespans.
  • Utilize flow data for people visiting hospitals to eliminate patients’ waiting time (full-scale operation in FY2019)
    Measure and analyze the movement of patients after arrival at the hospital, identify where stagnation is occurring, and make related improvements. By setting up remote check-in when the outpatient arrives at the station, the patient can effectively use their waiting time in the Kashiwa-no-ha area, and they can be given instructions for commuting to the hospital (parking information, bus information).
  • 3 Wearable devices: Refers to devices that are used while worn on the body, and which use sensors to measure variables such as the wearer’s pulse and activity level
  • 4 Sheet-type pressure sensor: A sheet-shaped pressure sensor used to measure breathing during sleep and body movements
  • 5 Receipt data: Healthcare remuneration statement data that medical institutions bill to insurers (municipalities and health insurance associations, etc.) related to healthcare services received by patients and which are covered by insurance

Data Use Policy

The Kashiwa-no-ha Smart City Consortium links two platforms: a private platform that collects information in the private sector related to people, the environment, and facilities in the Kashiwa-no-ha area, and a public platform that collects data gathered through government services, and builds a system that allows data to be used across the two platforms. By promoting the shift to open data, the public platform will be able to use data in collaboration with private platforms, and will create new applications and services through cross-sectoral data analysis and utilization.
