I am a jazz pianist, mathematician, STEAM educator, and the thematic producer at World Expo 2025, Osaka, Kansai, Japan about play/ learning/ art/ technology. Together with Emi, a renowned improvisational ballet dancer, we are now pursuing the future of playful interactive civilized arts, integrating various physical senses, cutting-edge technology, math, and culture. In this talk, we will introduce our views about democratizing creativities hidden in each life, experiments of the integrated arts and workshops, and the Japanese unique concept of “asobi: play / emptiness”. We are also to show some fluctuating mathematical models behind real lives or nature, like the winds, waves, and insects-world. These projects are to be expanded worldwide to realize the META co-creative future society.
