A growing number of natural hazard-triggered technological accidents(Natech)has been reported by several researchers,and this trend is expected to continue due to climate change.As a result,some governments have initiated direct efforts to manage Natech risks,particularly in the United States and Europe.However,two surveys conducted by the Organisation for Economic Co-operation and Development(OECD)in 2009 and 2017 found that there was a lack of proper risk management and risk governance for Natech among OECD member states,including Japan and South Korea.This study aimed to identify relevant regulations and practical considerations for chemical and Natech risk management from government perspectives in Japan and South Korea.The article provides a review of the current state of risk management,emergency response,and risk communication on chemical and Natech risk management in the two countries,and concludes with a discussion of some of the issues that require improvement of the current chemical risk management.Current practices for chemical risk management in Japan and South Korea point to the possibility of improvements in dealing with the Natech risks.These practical lessons will be valuable for improving the capacity for dealing with challenges in chemical and Natech risk management.
