Fuyama got into 3DCG animation back in the '90s and has basically been innovating in the animation space ever since. Starting around 2003, he shifted focus toward developing tools and tech for making animation more accessible, while also running interactive workshops and exhibitions at museums across Japan and internationally. He's probably best known for creating KOMA KOMA, a stop-motion animation app that's racked up over a million downloads worldwide—which speaks to how intuitive the tool actually is.

Beyond the commercial stuff, his work spans some pretty varied territory. He's been involved in developing personnel training programs through partnerships between academia and industry, and he's also explored how animation can be applied to mental health contexts. He serves as Vice President of the Japan Society for Animation Studies, which makes sense given his depth in the field.
