About Me

I'm Jun Sasaki, a writer and creator based in Tokyo.

I believe in a future where technology amplifies human creativity rather than replacing it. My work explores the relationship between humans and AI through stories, products, and tools.

By day, I build businesses. By night, I write stories about the world I want to see in 2112.

LOG

One person in Japan, AI tools, five revenue channels. This is the build log.
