A path and strategy toward demonstration plant (DEMO) to achieve net electric power generation and to establish various technologies for successive commercial plants will be shown based on the Japan’s action plan for fusion energy development. It is clear that the fusion power plants may not be realized without a lot of technological innovations. Required innovations to attain the commercial plant as a final target of the DEMO plant are considered and variety of novel innovations introduced in previous reactor designs in Japan have been reviewed in order to prove a possible path to the fusion power plants.
