The study found five latent causes of the case of the Accident in the Maihime Attraction at Tokyo Dome; absence of the legitimate driver, failures in checking the safety bar, ambiguous provisions of limited availability, no interlock introduced, and lack of systematic education for part-time workers. Additionally it showed the loss of the sense of responsibility and excessive reliance on OJT (on-the-job training) as typical mechanism to induce organizational misconducts.
