    Evacuation of the 2011 Great East Japan Earthquake and Tsunami was a large-scale evacuation of over thousands of people escaping from the earthquake-induced tsunami. The survivors’ evacuation experiences provided valuable insights into the factors that helped with survival and some very important practical issues regarding tsunami evacuation. Therefore, this article analyzes an effectiveness of tsunami evacuation principles from descriptive comments from the survivors and the non-survivors in the 2011 disaster using text mining method. As a result using the Naïve Bayesian classifier, it identifies some of the evacuation behaviors differences taken by the survivors or by the non-survivors under the disaster as an effectiveness of the evacuation principles, and attempts to understand how to provide more practical instructions. Therefore, these results give effective recommendations for evacuation preparation against catastrophic earthquake and tsunami disasters in the future.
