Market Background

Recently, various natural disasters such as earthquakes and floods have occurred in every region of Japan, and business and local governments are raising interest in formulation of BCP (Business Continuity Plan) and disaster prevention measures. Therefore, the number of companies and municipalities introducing UPS (uninterruptible power supply) is increasing for the purpose of secure emergency power supply as reinforcing BCP countermeasure.

In addition, the ownership rate of smartphones in Japan exceeds 70%, and the importance of smartphones with various functions such as telephone, Internet, email, SNS, and map information is increasing in case of a disaster. As a solution to the smartphone charging problem at the time of disaster/emergency, PowerUPS enables battery charging of smartphones and tablets stably under any circumstances.


Future Development

Rikei will expand the business to local governments, companies that take disaster prevention measures, universities, and event venues across Japan.
