The number of Tsunami Evacuation Buildings is increasing after the Great East Japan Earthquake. However, a fact-finding for Tsunami Evacuation Buildings doesn't continue by Japanese government. Moreover, the guideline for Tsunami Evacuation Buildings was updated focus on structural requirements or positional requirements. For this reason, An actual decision of constructions of Tsunami Evacuation Buildings is left to the municipality's discretion. In this situation, constructions of Tsunami Evacuation Buildings have been improved without due thought or consideration for evacuation action because it's in the first stage that designate institution satisfied structural requirements for Tsunami Evacuation Building.
 So in this study, to elucidate concepts of Tsunami Evacuation Building planning that is going to effectively utilize, we focus on newly built Tsunami Evacuation Building and analyze the relation between spatial composition and function as evacuation facilities from there.
 For survey method, we used E-mail as questionnaire survey for 643 municipalities along the shore. And then, we contact them again for get information of building plan especially inside a building (like a floor plan or a cross section plan etc.) if they have newly built Tsunami Evacuation Buildings.
 The result of this study is as follow:
 1. Confirmed 9,103 Tsunami Evacuation Buildings from municipalities along the shore.
 2. Grasped tendencies of construction of Tsunami Evacuation Buildings by comparison with past surveys.
 3. Confirmed 77 newly built Tsunami Evacuation Buildings and grasped distributions, attributions and necessary conditions for constructions of newly built Tsunami Evacuation Buildings.
 4. Grasped patterns of spatial composition of inside a building from the formation of the architecture and volumes of staircase.
 5. Grasped functions as evacuation facilities in the newly built Tsunami Evacuation Building.
 6. Newly built Tsunami Evacuation Buildings may be divided into 2 types by organizing the relation between spatial compositions and function as evacuation facilities.
 Consequently, to grasp characteristics of newly built Tsunami Evacuation Buildings will help building new constructions.
