Akahama in Otsuchi, Iwate prefecture is one of the areas severely damaged by the Great East Japan Earthquake and Tsunami (3.11). A purpose of this paper is to clarify how residents used the evacuation places and shelters from emergency evacuation phase to refugee life phase in 3.11 in relation to the transition of disaster preparedness places and the transition of daily gathering places in order to get the suggestion about how to design a disaster preparedness place.
 In chapter 2, it is clarified that how evacuation places were used in three phases. In emergency evacuation phase, many residents evacuated to an elementary school, but there was flooded and many people got wet. In temporarily shelter use phase, residents could find a printing office near the school and about 140 people stayed there for 3 days. Many residents went to private houses and stayed. 3-chome residents could not find large facilities, so they went to a neighboring village. In refuge life phase, about 80 residents used the gymnasium of school, about 20 residents used welfare facility and 8 households used 2 vacant houses that were owned by Otsuchi-cho.
 In chapter 3 and 4, transition of disaster preparedness places and daily gathering places are clarified. In chapter 3, findings are as follows. 1) A damage of past tsunami was recorded, but evacuation behaviors or the places where people gathered was not passed down. 2) the understanding that a school was designated as a disaster preparedness place was widely shared. 3) In the late 80's, a numbers of preparedness place increased because of expansion of village. 4) In the late 90's, 1-chome's preparedness place was gathered to a school because a new gymnasium was built. 5) In the late 2000's, local organization decided that Akahama had 3 prepared places in terms of governance after a discussion that Hachiman Shrine didn't have a enough space. In chapter 4, findings are as follows. 1) A school and Community center had been the base of Akahama community. 2) A school had been the base of community, and that's why a school became center of disaster preparedness place in spite that there was not evacuation place during Sanriku tsunami of 1933. 3) A community center had been the base of community and located a little higher ground, and that's why disaster prevention materials was stocked before 3.11.
 In chapter 5, evacuation places and shelters in 3.11 are analyzed in three phases in relation to the transition of disaster preparedness place and daily gathering place. It is found that in emergency evacuation phase, a school had been known as a preparedness place in spite that in the past there was not evacuation place and gymnasium was located in dead end, and in 3.11 many residents were exposed to danger. In temporarily shelter use phase and refuge life phase, it can be necessary to think preparedness place not only inner village but also wider area, etc.
 In chapter 6, the following four points are suggested. 1) It is important to think the role of disaster preparedness place in the disaster phases. 2) Changes of a village environment and modernization of daily gathering place influence a numbers and characteristics of disaster preparedness place. 3) The actual condition of evacuation behavior such as gathering places in past tsunami disaster is necessary to be come up for discussion about the disaster prepared. 4) For the occurrence of a gap between evacuation places and disaster preparedness place, residential network is needed for a use of private houses or facilities, and also vacant ones owned by municipality should be prepared for an emergency evacuation.
