The Great East Japan Earthquake in March 2011 caused devastating damage to Japan. As part of this social contribution, the Sumitomo Electric Group has been holding Tohoku Product Fair annually since 2012, the year after the disaster. In 2020, conventional in-house sales events with physical showcases were canceled due to the COVID-19 pandemic.

Instead, in the Tokyo area, easily enjoyable foods produced in the Tohoku region were introduced through pamphlets for mail order, and cooperation was gained from many employees as usual. Sumitomo Electric will continue these kinds of activities in the future.
