Sakuranbo was completely destroyed. One day it was just gone. The Ouka nursing home suffered large scale partial destruction, but it might as well have been gone too. Even though the building itself remained, the electrical system was flooded and shot, and several cars had crashed into the building so it was completely useless. But this was considered large scale partial destruction. So an unusable building doesn’t equal a completely destroyed building.
At the time, the Ouka nursing home facility had just opened in July 2010, and after it was damaged on 3/11 2011, it was demolished in June 2012 to meet the demolition deadline. Two disabled group homes were also damaged and torn down.
Sakuranbo, a vocational support center for the disabled, wasn’t far from the Ouka nursing home facility, so everyone from those facilities evacuated together.
