In 2011, Tohoku Region Pacific Coast Earthquake attacked Japan and the Tsunami destroyed a number of cities completely. After 2 years, the way of revival are discussed right now. In the process, how the community can be reproduced becomes hot issue. The city vanished instantly, therefore, they need to reproduce not only buildings but also lifestyles. However, this is not first experience for Japanese. The war damage revivals were carried out after WWII. The purpose of this study is to investigate the revival processes from war damage in Japanese local cities and reveal the "Urban Kernel" from them. Urban Kernel is an implicit norm to reproduce urban fabric. By using this concept, an alternative viewpoint in city planning would be shown.
