Yahoo donateｄ 10 yen if one person searches the Tohoku great earthquake on March 11th. They did this not to make people forget and they donated all money to Great East Japan Earthquake Recovery Initiatives Foundation. Three years have passed since the earthquake happened, people are getting forgotten, even though the Tohoku area haven’t recovered. So, I think what Yahoo had done was great. We shouldn’t forget people live in Tohoku area are still suffering and they need our help.
