SFC is contributing to the Tokyo 2020 Olympic and Paralympic Games not only through its representative athletes but also through a wide range of research.
Here are some examples of the research and professionals supporting the Tokyo 2020 Olympic and Paralympic Games.
Algorithmic Design for the Tokyo 2020 NIPPON Festival Concept Video: Shohei Matsukawa, Associate Professor, Faculty of Environment and Information Studies
Associate Professor Shohei Matsukawa of the Faculty of Environment and Information Studies was in charge of the algorithmic design for the concept video of the "Tokyo 2020 NIPPON Festival," held as an official cultural program of the Tokyo 2020 Games.

NIPPON Festival Concept Video Production Staff:
Director: Asao Tokolo (Artist / Festival Mark Creator)
Algorithmic Design: Shohei Matsukawa (Architect / Associate Professor, Faculty of Environment and Information Studies, SFC, Keio University)
Taiko Drummer: Eitetsu Hayashi (Taiko Performer / Eitetsu Fuun no Kai)
Producer: Keiko Yamaguchi
Comment from Associate Professor Shohei Matsukawa
The three logos—the emblems for both the Olympic and Paralympic Games, and the mark for the NIPPON Festival—may seem completely different at first glance, but in fact, a common geometric principle is hidden behind them. Asao Tokolo, who designed the three emblems, calls this principle "Ritsu" (rhythm/law). I translated this "Ritsu" into a computer algorithm Note 1 . The NIPPON Festival concept video is a visual work that expresses the myriad patterns generated from this common "Ritsu," set to the rhythm of the Japanese taiko drums played by Eitetsu Hayashi. I hope this will be an opportunity to convey to as many people as possible the richness of design made possible by the existence of "Ritsu."
Manufacturing Design of the Tokyo 2020 Olympic and Paralympic Games Victory Ceremony Podiums Using 3D Printers: Hiroya Tanaka Lab, Professor, Faculty of Environment and Information Studies
Professor Hiroya Tanaka served as the design supervisor for the project to produce the victory ceremony podiums for the Tokyo 2020 Olympic and Paralympic Games using 3D printers. In addition, graduates, researchers, and students from the Hiroya Tanaka Lab collaborated to handle key parts of the process, from research and development to manufacturing design. The podiums for these Games were made from recycled plastic for the first time in history, as part of the citizen-participation "Tokyo 2020 Podium Project." A total of 24.5 tons of resources were collected from approximately 2,000 major supermarkets and drugstores, as well as 113 schools, companies, and organizations nationwide. The design was handled by artist Asao Tokolo, creator of the Games' emblems, while Tomoki Hiramoto (a graduate of the Hiroya Tanaka Lab who completed his master's degree at the Graduate School of Media and Governance in FY2010) created the potential for 3D manufacturing and directed the entire project, including the color-tuning design.
Comment from Professor Hiroya Tanaka
We received the request to participate in this project in the summer of 2019, at a stage when the beautiful geometric design by artist Asao Tokolo and the use of "recycled plastic" collected from all over the country as the material had already been decided. What was required of us was to find a manufacturing method that could bridge the gap between "design" and "material." At the same time, we were presented with a wide range of complex design requirements: the podiums could not be too heavy for transport, we had to consider various lighting and camera conditions, and we had to mass-produce the required number of units in a short period. We concluded that 3D printing was the only way to proceed with the design while solving each requirement one by one, and then move directly to mass production to complete them within the deadline.
It is an unexpected joy as a researcher, educator, and engineer that a cross-generational collaboration was realized by our lab's graduate Tomoki Hiramoto, researcher Ryohei Yuasa, and master's student Soya Eguchi. By working together, they solved numerous problems and successfully led to the mass production of 98 podiums.
Currently, the post-Games use (reuse) of these podiums is being discussed. Taking materials that would have otherwise been discarded, adding value to them through 3D printing, and then sublimating them into "something that will be used for a longer time" to be sent back into society. I have named this process "Leap Cycle." Going forward, while collaborating with specific sites, regions, and projects through the Keio University KGRI "Research Center for Circular Design and Digital Manufacturing," which was established in the fall of 2020, I intend to research and promote the potential of 3D printing to the world from the perspective of contributing to the Earth's sustainability by promoting the transition to a resource-circulating, decarbonized society.
