To cope with increasingly severe and frequent heavy rains, we are proceeding with measures such as river widening, and constructing retention ponds for temporary flood storage.In order to reduce flood damage at an early stage, we are focusing on areas with a high risk of flooding, and are promoting the development of sewerage facilities, such as trunk lines and storage facilities.The municipalities are making easy-to-read flooding hazard maps, which indicate flood damage estimation and evacuation methods. TMG, together with relevant organizations, supports the municipalities in the preparation and release of these maps.This is a toolkit to prompt awareness of flood evacuation on a daily basis in order to help city residents correctly understand weather information and enable them to take evacuation measures that suit their environment and the characteristics of their region. In addition to a printed version, the contents are also available as part of the Disaster Preparedness Tokyo app. In order to make it easy to create a My Timeline on your smartphone, it is equipped with a chatbot function and a “My Timeline Dictionary” that explains technical terms related to weather with videos. Please also refer to the creation support video on the Tokyo Disaster Preparedness website.We have created a flood risk map that allows you to visually check possible flood risks in Tokyo, such as river flooding, storm surge inundation, and sediment disasters. This is provided on the Disaster Preparedness Tokyo app. Users can also immediately check the risk of flooding in their current location by linking it to their GPS.VR videos are available on the TMG Disaster Prevention website, the TMG Official Video Channel, etc., to simulate the threat of wind and flood damage and to learn what actions to take in case of emergencies.In order to prevent flooding from entrances/exits of subways, disaster prevention doors and watertight doors have been installed. Watertight doors have also been installed in tunnels in order to help limit damage in the event of flooding.Check dams and other measures are being implemented in areas where there is a high risk of mudslides or where mudslides have occurred in the past. When developing these facilities, we are proceeding in order of urgency and effectiveness in protecting human life, considering evacuation centers that are difficult to relocate and facilities related to people in need of assistance.flip-up flood barriers(8) Storm and Flood Damage　Precautions1.
