Abstract
A small town, Otsuchi, located at the coastal area in Iwate prefecture was completely
damaged by the Tsunami on March 11, 2011. Taking two issues as examples, author tries to reveal
the difficulties of decision making process of reconstruction planning. One is the results of land
readjustment project at Machikata area where only a half of planned residents will come back. The
other is the preservation of former town office as a remain which tells how severe is the Tsunami
damage. It is our responsibility to hand on these knowledges by reviewing these experiences in order
to utilize them for the expected future disasters.
