The International Toki Conference (since 1989) is a topical meeting dedicated to the future of fusion and plasma science. Under the title of “Expanding academic world emerging from fusion science”, the 31st conference(online) in 2022 will be held as a world-wide forum for international and interdisciplinary discussions towards the universalization of fusion and plasma science.

The conference is organized by eleven special sessions to present the academic plans and prospects for a new phase of the National Institute for Fusion Science (NIFS), as well as related plenary/invited talks and contributed poster sessions. Focusing on the universal questions raised in the conference, each organized session will contribute to lay the foundation for sustainable future science and technology by integrating academics. It is our hope that the values and importance will be shared with all participants.

The ITC31 is motivated by the recognition of a paradigm shift occurring in fusion science. So far, fusion science has focused on “numerical targets” that represent the access of plasma parameters (temperature, density, etc.) to the thermonuclear range, and has promoted big projects that literally pioneer the new frontier. In parallel to pushing parameters, these projects have revealed the basic problems that make up the “reason” behind the “results”.

We have reached a level where fusion science can be developed as diverse themes bearing academic meaning. NIFS will evolve into an academic research institute symbolized by the theme of “well-posed and well-defined problems” representing fusion science. We will develop academic issues in science and engineering in an interdisciplinary manner through eleven Units (groups). We will systematize fusion science academics while striving to deepen and universalize research results and hand them down to the next generation and the next generation after that.
