In Japan, there is growing concern about tsunamis associated with potential Nankai Trough earthquakes, which are expected to cause significant damage. As countermeasures implemented solely by administrative bodies are insufficient, it is imperative for individual community residents to consider and implement tsunami countermeasures as their personal responsibility. Previous research has demonstrated that tsunami evacuation simulations can be effective tools in promoting local tsunami evacuation measures. However, due to the complexity of creating these simulations, they have not been widely utilized in communities without ongoing expert involvement. Therefore, this study proposes a resident-led tsunami evacuation simulation approach, aiming to empower local residents to take the initiative in creating tsunami evacuation simulations and to facilitate their consideration and proposal of tsunami evacuation countermeasures within their communities. To achieve resident-led creation of tsunami evacuation simulations, we conducted a validation experiment targeting junior high school students, based on a tsunami evacuation simulation creation method proposed using Scratch. The experiment aimed to determine whether students could configure tsunami animations and create evacuation models, as well as to identify any challenges in the creation process. Results suggest that junior high school students could potentially set up tsunami animations and create evacuation models. Additionally, based on the identified challenges, an auxiliary program to assist in the creation of simulations was implemented for subsequent validation experiments.
