JR East is faced with the need to pass on skills and knowledge to the next generation and improve safety consciousness. As an effort in this direction, the company developed a safety portal site on the intranet to facilitate the sharing of safety-related information. This site has been expanding company-wide since 2007. On this site, employees can share information and know-how regarding the prevention of errors and deepen their understanding of human error. In other words, this site supports employees as they improve the safety of railway transport in daily operations and advance as professionals.
