About half the city was inundated by the tsunami. The tsunami destroyed all but 30 of 650 fishing boats and completely wiped out the town's sea farm industry.

Fort Bragg students visited Ōtsuchi in 2002 and the sister-city proclamation was solidified in 2005 by subsequent Mayor, Dave Turner. Other student exchanges were held in 2004, 2006, 2008 and 2010 and the next exchange was planned for July 2011. Following the 2011 Tōhoku earthquake and tsunami devastation Mayor Turner ordered that city flags be flown half staff until the end of March to honour the thousands of lives lost.
