This study aims to analyze and describe terrorism-related attacks in East Asia from 1970 to 2020. This descriptive analysis of terrorist attacks in East Asia will help first responders, emergency medical services (EMS), hospital-based medical providers, and policymakers establish a more refined hazard vulnerability assessment framework and develop a counter-terrorism medicine (CTM) mitigation, preparedness, response, and recovery plan.

This descriptive observational study draws data from the Global Terrorism Database (GTD) from January 1, 1970, to December 31, 2020. Epidemiology outcomes included primary weapon type, primary target type, the country where the incident occurred, and the number of total deaths and injuries collected. Data from 2021 was not yet available at the time of this study. Results were exported into an Excel spreadsheet (Microsoft Corp.; Redmond, Washington USA) for analysis.

There were 779 terrorism-related events in East Asia from 1970 to 2020. In total, the attacks resulted in 1,123 deaths and 9,061 persons injured. The greatest number of attacks (371; 47.63%) occurred in Japan and the second most occurred in China (268; 34.4%). Explosives were the most used primary weapon type (308; 39.54%) in the region, followed by incendiary devices (260; 33.38%). Terrorist attacks drastically diminished from their peak of 92 in 1990, but there were additional peaks of 88 in 1996, 18 in 2000, 20 in 2008, and 36 attacks in 2014.

A total of 779 terrorist attacks occurred from 1970 to 2020 in East Asia, resulting in 1,123 deaths and 9,061 injuries. Of those, 82.03% of attacks occurred in Japan and China. Terrorist attacks drastically diminished since their peak in 1996, but there is an overall uptrend in attacks since 1999.
