On March 11, 2011, the power system suffered heavy damage from the huge earthquake and tsunami in the Tohoku region. This paper describes the change of features included in the time series of open demand data for the disaster of 3/11/2011. The demand data are separated into three sections: one for the "predisaster" analysis from April 2008 to February 2011, the second for the "during-disaster" survey from March to May 2011, and the last for the "postdisaster" analysis from June 2011 to March 2013. We distinguished the periodic components of daily, weekly, and seasonal fluctuation among the demand time series by applying a newly developed procedure, the quasi-ideal moving average method. Some significant changes were observed in the statistics of the predisaster and postdisaster periodic component analysis. The change in temperature sensitivity was also surveyed by using open weather data for Sendai.
