Abstract
This paper describes the development plan toward realization of Fusion Energy. In the first part of the paper, a principle of TOKAMAK system which is the most successful magnetic-confinement-systems for fusion reactors are shown, and then the ITER project based on TOKAMAK and the present status of ITER is described. In the next part of the paper, a roadmap for fusion energy which was published by the Fusion Energy Forum of Japan is described. In the final part, two examples of Demonstration Reactor Concepts considered in Japan are briefly reviewed.
