Providing Visualized Information on “Safety and Security”
Installation of CO2 Concentration Monitors for Customers at Aeon Stores

AEON RYUKYU CO. LTD. (Headquarters: Haebaru Town, Okinawa; Keiji Ono, President; hereinafter“Aeon Ryukyu”), in order to offer a shopping environment with enhanced “safety and security” during theCOVID-19 pandemic, has installed CO2 concentration monitors (hereinafter “the Monitors”) at six Aeon
stores and at Aeon Town Toyomi Shopping Center in Okinawa Prefecture to allow customers to confirm
for themselves the ventilation conditions.
The state of emergency declared due to the spread of COVID-19 has been extended in Okinawa
Prefecture until September 12, and the prefecture has outlined polices to reinforce measures during thestate of emergency to prevent the further spread of COVID-19.
Under such circumstances, the installation of the Monitors at large-scale commercial facilities willallow customers to confirm safety and visualize information to help reduce congestion, leading toproviding a safer and more secure environment.
The Monitors, jointly developed by AEON DELIGHT CO., LTD. (Headquarters: Chiyoda Ward, Tokyo;Kazumasa Hamada, President & CEO and Group CEO; hereinafter “Aeon Delight”) and amanufacturer, are a part of the “Network-type CO2 Concentration Monitoring System” (hereinafter, “theMonitoring System”) introduced in early April, which can remotely check the CO2 concentration
measurement results as needed.

CO2 concentration measurement results
are updated every minuteMonitor installed near the entrance,next to the grocery section

The Monitoring System introduced this time takes the CO2 concentration data measured with the CO2
sensors and through communication with a cloud server displays the results on a large monitor in aremote location.
The Law for Maintenance of Sanitation in Buildings (Building Maintenance Law) stipulates that CO2
concentration in large-scale commercial facilities with total floor space exceeding 3,000 sqm must be-1-

maintained at a level 1,000 ppm or lower.
The Monitoring System measures CO2 concentration in real-time, and the average level for the past
30 minutes is updated every minute on the monitor. This allows store customers to visually confirm theCO2 concentration and instantly check that proper ventilation is being carried out. In case the CO2
concentration exceeds 1,000 ppm, the system sounds an alarm at the store office or disaster prevention
center, which results in reinforcing employees to ventilate as necessary.
The Monitors were originally designed mainly for installation at locations such as store offices ordisaster prevention centers where employees can see them. However, considering the recent trend dueto the COVID-19 pandemic that calls for the provision of objective information, they were installed nearthe entrance of six large-scale Aeon stores and at the food court of Aeon Town Toyomi Shopping Center,
which aims to provide information on safety that customers themselves can confirm and help reducecongestion.
