The superiority of Japanese shipbuilding is due to the strength of its continuous development of energy saving technologies. Japan has lead the world in implementation of technological development, from that in still water to actual ocean conditions and from the development of both hard and soft technologies. It is important in future that Japan also lead the world in developing technologies to optimize all facets of navigation at sea and to create global standards for related technologies.
