Kazuki Otsuka (1985-)

Kazuki Otsuka is a Tokyo-based programmer, an independent computational evolutionary scientist, and a contemporary artist.
Since first becoming interested in why some melodies are better at age 16, he has consistently explored extending the original field of aesthetics—defined since Baumgarten in the 18th century as the study of perception under cognition—through formal logic, researched musical structure while studying overseas in France, and continued this work as a university researcher and beyond.
He calls this proposed field of study and artistic philosophy “Transformism.”

As a serial entrepreneur, he has led numerous software projects, carrying out every stage—including infrastructure, backend, interfaces, and AI-based mathematical modeling.

Kazuki worked mainly on,
