Yukio Ohsawa

PhD, Professor

Department of Systems Innovation

School of Engineering,  The University of Tokyo



Yukio Ohsawa is a professor of Systems Innovation in the School of Engineering. He received BE, ME, and PhD in from the School of Engineering, The University of Tokyo (1995). Then worked for the School of Engineering Science in Osaka University (research associate, 1995-1999), Graduate School of Business Sciences in University of Tsukuba (associate professor, 1999-2005), and moved back to The Univ. of Tokyo. He started researches from non-linear optics, and, via artificial intelligence, created a new domain chance discovery meaning to discover events of significant impact on decision making, since year 2000. About chance discovery he gave keynote talks in conferences such as International Symposium on Knowledge and Systems Sciences, Int’l Conf. on Rough Sets and Fuzzy Sets, Joint Conf. on Information Sciences, Knowledge-Based Intelligent Information and Engineering Systems, etc.


Chance discovery came to be embodied as innovators’ marketplace, a methodology for innovation borrowing principles of the dynamics of markets. Then he, when biking from his job in a business school, invented the basic idea of Data Jackets as a new tool for enhancing chance discoveries via combining data from various data owners. Since then, he is introducing the method presented in this book to sciences, educations, and businesses. His original concepts and technologies have been published as books and monographs from global publishers such as Springer Verlag, Taylor & Francis, etc. Two most important books among them are, “Chance Discovery” (2003 Springer, foreword given by Eric von Hippel), “Innovators’Marketplace: Using Games to Activate and Train Innovators” (2012 Springer, foreword given by Larry Leifer). He edited special issues as guest editors for journals, mainly relevant to chance discovery, such as Intelligent Decision Technologies (2016), Information Sciences (2009), New Generation Computing (2003), Journal of Contingencies and Crisis Management (2002), etc.


As the program chair of the Annual Conference of The Japanese Society on Artificial Intelligence, he is the first to change this domestic conference into an international conference from June 2019.


How Can We Live in the Age of Opacity? -Human-Data-AI Symbiosis and Specialization-

Behaviors of unseen human beings and things have been accumulating as mixed rich data. Thanks to such ever-accumulating data, however, can you see more visibility of the world? Rather, more of you think the intelligence for data utilization or AI is increasingly complex and invisible. Would it be better to join and allocate naturally-ever-scaling data effectively? Also, because of the computing system, inherently AI has superior learning capabilities which are far beyond human being’s. Would it be better to utilize such superior learning capabilities of AI? In this session, we explore this challenge through the concept of “data jackets” and “synthesis & specialization-based innovation.”



Dai Tamesue

President, Deportare Partners 



He was born in 1978 in Hiroshima. He is the first Japanese sprinter to win a medal in a track event at a World Competition. Also, he is the Japanese national record holder for Men’s 400 meter hurdle (as of January 2019). Currently, he acts as the head of Deportare Partners for “Sports x Technologies” initiatives to bridge between athletes and business partners. Also, he works as the head of the Shin-Toyosu Brillia Running Stadium. He wrote many books including “Philosophy for Running” (Japanese), “Power of Give-up” (Japanese), etc.


Data and Sports

In the domain of sports, the boundary between superstition and reality is fairly dark. Many athletes shown on the front cover of a famous sports magazine “Sports Illustrated” become impaired in their condition after one month later. It’s often said to be the curse of the front cover. In reality, it can be explained by mean reversion. How many minutes should we do for good warm-up exercises? When should we decide player substitution? Why is Japan good at 4x100 meter relay? Simply “data” teaches the boundary between superstition and reality. More specifically speaking, the reality can be seen by analyzing disordered messy data. Athlete performance has been clearly improved since the 1980s after adoption of physical trainers. Now, we may say “win or lose” depends on whether using data analyst(s) or not.
