The Great East Japan Earthquake drastically changed Japanese energy management scheme in Japanese electrical grid. Stopped nuclear power plants caused a rise of the electricity costs. Demand side energy management scheme such as demand response is newly needed to reduce the peak of electric power demand by using HEMS (Home Energy Management System) and BEMS (Building Energy Management System). This paper describes Japanese trend of energy management based on demand response and international standardization of communications protocol and indicate the future issues and vision.
