Since the Great East Japan Earthquake struck northeastern Japan on 11 March 2011, electricity saving has been a major problem in Japan. This study aims to investigate actual effects on energy saving in the residential and commercial buildings on the basis of a questionnaire survey in the service areas of Tokyo Electric Power Company (TEPCO). The result shows that electricity consumption in residential buildings (households) after March 2011 declined by almost 8-9 percent compare to the same period of the previous year without any restriction on households' electricity consumption. Among the energy saving measures applied by households, the measures related to lighting, air conditioning have made significant reductions in energy use. In addition, people's efforts in electricity conservation are deemed to continue to some extent in residential buildings. In office buildings, the electricity consumption declined by 17.6 percent from April to August 2011. The large-lot users were required to reduce peak-time electricity consumption by 15% compared with a year earlier. However, unlike the residential sector, continuous electricity saving activities in commercial sector is still uncertain.
