CI design begins with its Mark. 
If one asks what CI (Corporate Identity) design is about, my answer is, “It is a Mark.”  The Corporate Mark is designed as the symbolized portrait of the subject’s inner es- sence. The Mark is a symbol of corpora- tions, organizations, and individuals. With- out a Mark, they cease to exist; there- fore, it begins with a Mark.
A graphic designer, first and foremost,   must confront CI design, and master Mark design. For the application of CI, the de- signer must be a professional, and an expert in various fields. When I was twenty-four years old, I came to realize the CI designers’ privileges, which are to integrate visuals across various design fields, and to provide art direction to corporate and organi- zational clients in the role of consultant.
I was enlightened at the age of twenty- seven and shifted my focus from advertise- ment design to CI design. At thirty, I completed my design philosophy and built the foundation of Inayoshi-style CI de- sign. To date, my philosophy and my style have stayed consistent without a flaw. The CI designs and Personal Identity (PI) de- signs included in Vol. 1 of Hiromi Inayoshi CI Design are carefully selected as the rep- resentation of Inayoshi style, from a se- ries of works I have created in the past thir- ty years. For the next generation of de- signers, the book is structured in such a way that the quality and the level of design- ers will be uplifted by going through it. It is, so to speak, a design bible, as well as a design instructional book. CI design is an ul- timate integral design that enables people to imagine and create the future.
This collection of works is inlaid with core essences and I proudly assert that all of these works and designs will be permanently recorded in the history of art and design.
