About

Masayuki Hirasawa is a dedicated researcher in construction safety and occupational risk management, with a focused expertise on improving worker safety at roadway work sites in Japan. His major contributions center on analyzing longitudinal accident data to identify trends and priority areas for intervention. In his most-cited work, "Study on Improving Worker Safety at Roadway Sites in Japan" (2007), Hirasawa documented a dramatic decline in construction-related fatalities—from 1,001 in 1996 to 487 by 2005—and highlighted that traffic accidents remained the third most common incident type at roadway sites between 1996 and 2000. By tracing the impact of policy changes initiated by the Ministry of Health, Labour and Welfare after 2001, his research provides evidence-based guidance for targeted safety improvements. Though his citation counts are modest (5 and 2), Hirasawa’s work offers critical, data-driven insights for practitioners and policymakers seeking to reduce risks in one of Japan’s most hazardous work environments. His studies serve as a valuable resource for students and researchers in construction safety engineering and occupational health.
