About 4.3 million people volunteered in disaster relief activities in Japan, during a one-year time period, between October 2010 and October 2011. The number is three times higher than the one reported in the previous survey in 2006, according to the information released on Monday by the Internal Affairs and Communications Ministry.
An estimated number of 4,317,000 people have volunteered to help survivors of the devastating March 2011 earthquake and tsunami as well as other natural disasters in Japan, according to Kyodo news agency.
By prefecture, the ratio of those involved in disaster relief hit 11.1 percent in both Iwate and Miyagi, 6.9 percent in Yamagata and 6.5 percent in Fukushima. These prefectures have been most affected by the March 2011 quake and tsunami in Tohoku.
By age bracket, over 5 percent of the volunteers were 35 to 54, and 6.0 percent — the highest percentage — were college and graduate school students.
The survey was conducted in 2011 and analyzed the social life of about 200,000 Japanese people aged 10 or older.
The results were released before the 18th anniversary on Thursday of the Great Hanshin Earthquake, designated as a day for disaster prevention and volunteering in Japan.
