Disaster prevention policies as climate change adaptation are important. The government has modified laws to reflect climate change. Local governments that actually implement disaster prevention policies to protect citizens are now required to prepare for the largest flood events. However, it is difficult to protect against floods that will expand due to climate change.

Therefore, government-led soft measures, such as the provision of information through hazard maps in advance and evacuation guidance at the time of a disaster, will be the main solution.

Local governments are under pressure to cope with floods, which are expected to change more drastically than in the past, and are obliged to save lives, including those of the elderly and other vulnerable people. However, it is difficult for disaster management departments to conduct specialized simulations that take into account the effects of climate change.

Kochi University of Technology (KUT) and Kochi City Office have established a cooperative system as part of the SI-CAT, and cooperated to conduct a disaster prevention workshop style drill conducted by the Disaster Prevention Policy Division. This Division conducted a more practical drill using data on inundation analysis provided by KUT.

Under the current situation, staff members consider and implement countermeasures only after the damage is reported. Therefore, there was a time lag between the occurrence of damage and the implementation of countermeasures to demonstrate their effectiveness. If damage forecasts were shared and countermeasures were implemented in advance, the time lag would be reduced and evacuation orders and post-flood recovery activities can be carried out smoothly according to damage reports and damage expansion forecasts. In the discussions between KUT and division supervisor, we were able to find that this flow is the ideal image to aim for in disaster response.

In Kochi City, heavy rainfall is difficult to predict meteorologically, and it takes only a few hours for floodwaters to reach urban areas after heavy rains occur. Therefore, the government needs to protect the lives of citizens and respond quickly.

The purpose of the "Disaster Countermeasures Headquarters Workshop Training" is to improve disaster response capabilities as senior officials through imagining the damage and countermeasures. The two main points of the training were to "estimate future response items based on the situation at the time of the disaster" and "understand the necessity to start considering disaster response as early as possible. In February, as a test case, a trial drill was conducted with several groups of senior officials.

As a prologue, the recent torrential rain disasters were explained. Furthermore, as a common scenario, administrative responses such as the opening of evacuation centers, weather information such as typhoons, and data on flooding and the number of evacuees after the floods were presented.

Next, individual participants wrote down their responses from the first day to the third day and up to one week later. Next, each group did group work to organize and summarize their responses. In the final stage, the results were presented to each other.

The participants were able to experience and understand their roles in the time line. In addition, they were able to infer the phenomena that will occur in the future and come up with early responses. It is expected that the participating executives will expand their experience in their own departments.
We plan to develop the questions to reflect the change climate change, and to present the spread of inundation, the number of evacuees, and disaster waste in a way that participants cannot predict. In addition, we will continue to deepen operation process in the next year and beyond.
