YE DIGITAL（旧：安川情報システム） Company Profile

YE DIGITAL and Pacific Consultants Co., Ltd., a major construction consulting firm, signed a memorandum of understanding in July 2021 to combine their respective IoT technologies and consulting expertise to provide solutions for reducing the increasing risk of flooding. In recent years, the risk of flooding has risen to unprecedented levels due to large typhoons, linear precipitation zones, and sudden heavy rains, necessitating a response. While river monitoring using IoT technologies such as cameras and sensors has been expanding in rivers managed by the national government, local governments are forced to rely solely on existing water level gauges for monitoring smaller rivers, making the establishment of a monitoring environment utilizing IoT urgently needed. Through collaboration with Pacific Consultants, which possesses high expertise in disaster prevention and mitigation as a construction consultant, we will not only provide river monitoring through the installation of cameras and sensors but also propose installation locations based on the characteristics of rivers and watersheds, and offer effective disaster prevention support, thereby achieving a reduction in flood risk for local governments.

In the utilization of LPWA (LTE-M) technology. Research by YE DIGITAL Takamatsu Teisan Co., Ltd. has started the operation of a gas level monitoring system using the fuel remote monitoring system "Miru Tank," provided by YSC Co., Ltd. and YE DIGITAL, since February 2021. Users of industrial gases procure gas from sales companies like Takamatsu Teisan and store it in cylinders or tanks. They visually check the remaining gas level daily, and if the level is low, they need to place an order via phone or other means. However, this manual checking process poses risks of stock depletion for users due to potential oversights or delays in verification, and it can lead to emergency deliveries for sales companies. To address this issue, Takamatsu Teisan has been promoting the introduction of a gas level monitoring system for several years. However, installation requires electrical work, which incurs initial labor and costs, along with ongoing running costs, resulting in limited implementation. Now, we have decided to introduce the remote monitoring system "Miru Tank" sold by YSC. For more details, please check the news release on our company website.

Nishitetsu Bus Kitakyushu Co., Ltd. will introduce smart bus stops provided by Nishitetsu M-Tech Co., Ltd. and YE DIGITAL Co., Ltd. at all bus stops on the two Kitakyushu Airport Airport Bus routes (Kokura route and Orito/Kurosaki/Gakken City route), starting operations on March 21. This will be the first time in Japan that smart bus stops will be operated at all bus stops from the starting point to the endpoint of a bus route. The two Kitakyushu Airport Airport Bus routes being introduced have had their schedules revised to align with aircraft operation times, and employees are currently replacing the timetables at each bus stop as needed. Due to the recent impact of the COVID-19 pandemic, aircraft operation times have been frequently changed, resulting in a workload for the year 2020 that is approximately ten times greater than usual. This introduction will lead to significant efficiency improvements in bus stop management operations. Additionally, new bus stops (timetables) specifically for the Kitakyushu Airport Airport Bus will be introduced separately from existing bus stops. By distinguishing these bus stops from others, a clearer bus stop environment will be established. For more details, please check the news release on our company website.
