[en] A 'strategic roadmap' to identify the activities of the FBR development for the next 10 years or so was decided at the Nuclear Ministerial Meeting in December 2018. In the strategic roadmap, in addition to the long-term development schedule, development policy, development system, etc., the role JAEA should perform are shown, such as the necessity of maintaining 'a needs-based research base capable of responding to various technological developments undertaken by the private sector.' In response to this strategy roadmap, JAEA has formulated an approach for future R&D on fast reactor cycles. This paper reports the outline. (A.O.)
