Abstract
This research investigates Nagano Prefecture that is taking a proactive approach to the rapid increase in mountain climbing incidents. The incident records were analyzed with the cooperation of the Prefectural Police, the main risk management organization. Findings revealed a close relationship between climber demographics （gender, age, number in group）; temporal （year, month, time）; and spatial dimensions （area and climate） of the incidents. A questionnaire was also conducted on climbers in the Northern Japan Alps. Only half the respondents collected information about prior incidents. Also internal factors （psychological and physical） contributed more to injuries or anxiety than external ones （natural environment）. By combining the epidemiological data with the questionnaire results, these findings use empirical evidence to help deepen climbers' crisis awareness and preparation.
