## About

Hi, I’m Yu Yoshimuta, a builder based in Tokyo.

I explore how AI can become a natural part of the way people think, create, and work.

I try to listen closely, question my assumptions, and learn from people who see the world differently from me.

## Notes

### Building this portfolio

Jul 27, 2026

A short note on turning four flat patterns into one navigable three-dimensional object.

Today I finished the first version of this portfolio. It begins with one three-dimensional sculpture that resolves into four graphic patterns from four different viewpoints.

Hope you'll enjoy it:D
