Abstract
There are a lot of drowning accidents occurring on sea bathing areas every year in Japan. In this study, actual situations of beach accidents of Japan caused by drowning and the first aid were investigated using lifesaver's reports. The drowning accidents including unconscious victims were from 1,000 to 3,000 cases every year starting from 1998 to 2015. Also, the first aid was carried out 10,000 to 25,000 times every year in the same period. In addition, the outbreak factors of drowning and injury/disease names were cleared. In order to reduce drowning and first aid, the beach risk assessment method to understand potential risks and an appropriate beach management was proposed.
