Since the 3.11 earthquake, we have visited more than 50 evacuation facilities and installed over 1800 units (2mx2m) of our Paper Partition System, to ensure privacy between families. During that time, I heard the news that the town of Onagawa was having difﬁ culty to construct enough temporary housing due to the insufﬁ cient amount of ﬂ at land. Therefore, we decided to propose three-story temporary housing made from shipping containers. By stacking these containers in a checkerboard pattern, our system creates bright, open living spaces in between the containers. The standard temporary houses issued by the government are poorly made, and there is not enough storage space. We installed built-in closets and shelves in all of our houses with the help of volunteers and with the donation fund. It will become a breakthrough and precedent to new government standards of evacuation facilities and temporary housing.
