Kentaro Koga

Hi, I'm Kentaro Koga – a freelance designer and creator based in Tokyo, Japan.

I work mainly in digital design and no-code development, while also exploring photography, illustration, and making small things that feel good to me. I value simplicity, quietness, and the beauty found in the unfinished.

I create web-based projects with a friend as part of a team called “Fump,” focusing on flexible and thoughtful design.

I don't chase big titles or awards. I'm more interested in meaningful work and slow, sustainable living.
