In 2018, many disasters occurred consecutively in various parts of Japan, including earthquakes, heavy rains, and typhoons. In particular, the earthquake that hit the northern part of Osaka Prefecture on June 18, the Heavy Rain Event of July 2018 centered on West Japan starting June 28, Typhoons Jebi (1821) and Trami (1824), and the earthquake that stroke the eastern Iburi region, Hokkaido Prefecture on September 6 caused damage to a wide area throughout Japan. The damage from the disaster was further extended due to other disaster that occurred subsequently in the same areas. The consecutive occurrence of major disasters highlighted the importance of disaster prevention, disaster mitigation, and building national resilience, which will lead to preparing for natural disasters and protecting people's lives and assets. In order to continue to maintain and improve Japan's DRR measures into the future, it is necessary to build a "disaster conscious society" where each member of society has an awareness and a sense of responsibility for protecting their own life.
