CHIERO INC.
The world is always tilted somewhere. Find the gap, bet your own capital, and turn it into something that keeps running on its own. CHIERO Inc. is an investment and R&D company based in Fukuoka, Japan.
Art, books and advisory work belong to the same flow. Revenue from that work goes into what we make next.
Investing on our own judgment, and research and development using AI. We keep only what survives verification. This is the core of turning tilt into structure.
Sitting alongside business owners as they make decisions. Not handing over answers from outside — putting into words the answer the owner already holds but has not yet been able to say. Where and how to put AI into a business gets decided here too.
Over 200 books published. Through books and social media, we record ways of thinking and the tools that go with them, and deliver them to the people who need them.

A point has no position of its own. It is fixed only by its relations to the other points.
Take the relations away and the shape goes with them.
Forty thousand points look like a living thing — not because of the points, but because of what holds between them. Thin the points out on screen and, at some count, the shape is gone. The same equation is still running.

CHIERO — Kou Nakata
FOUNDER & CEO
Born in Fukuoka, Japan. Studied IT and medicine at Kyushu University Graduate School, then left the research path to become a professional street performer — on the streets of Fukuoka and Tokyo, and as far as Sydney, Australia. Juggling and magic, stopping a hundred people in the first thirty minutes.
After about two years at an IT company in Tokyo working on marketing and problem-solving, he returned to Fukuoka and founded CHIERO Inc. in December 2020. Today he works on investment and R&D funded by his own capital, advises business owners, builds products, and writes. In April 2026 he completed “AI Business Insights 2026,” the AI Management endowed course at the University of Tokyo.
This is a one-person company, so the company's history and the founder's are not kept apart. They are the same line.

Each service requires its own account. Answers are generated by the AI from the primary sources — we do not write them. Gemini has no way to open with a pre-filled question, so there is no button for it.
