There was high-level commitment from the Ccbinet for the programme and strong tripartite involvement. It galvanised the efforst of all stakeholders and as a result, OSH accidents eventually began to reduce in 1962. This programme was an integral part of Japan’s national OSH system to achieve continuous improvements in OSH. The programme has been periodically reviewed and revised every five year; especially, the latest national OSH programme (11th national programme launched in April 2008) was developed in full reflection of ILO Promotional Framework for OSH Convention (NO. 187, 2006), of which Japan became the first country to ratify in July 2007. Using the Plan-Do-Check-Act(PDCA) cycle on a national lavel, the programme is reviewed and subsequent programme are launched to drive further OSH improvements.
