Since 1982, the tandem accelerator at JAEA-Tokai has been steadily providing various ion beams for basic researches on nuclear energy, open to the world for the utilization, and continuously upgraded. Its historic contribution to the basic research was appreciated by Atomic Energy Society of Japan as a historic landmark in nuclear energy. There have been a lot of activities in taking nuclear data at the facility also. This article is written, for Nuclear Data News from Nuclear Data Center, about the history of the tandem accelerator facility, its developments and utilization, nuclear data measurement for the development of nuclear fusion reactors and their contribution to JENDL-3 and -4, discoveries of new 17 isotopes among rare-earths and actinoides, effects of electric excitation in various solid-state matters under heavy-ion irradiation and so on.
