Fourth-grader Shinji Sato was born the week before the disastrous magnitude 9.0 earthquake and tsunami struck Japan's east coast in March of 2011.

Carried out of the hospital shortly before the tsunami swallowed up his coastal town of Yamada in Iwate Prefecture on March 11, Sato grew up strong and healthy in a community that benefited in its recovery from a group of sumo wrestlers who charged forward to provide aid.

Three months after the disaster, officials from the Japan Sumo Association visited Yamada and other areas to provide comfort and encouragement to victims by sending wrestlers out to interact with local communities.
