Our Identity

Taiho Oncology corporate symbol


Our corporate identity was designed to reflect the organization’s guiding principles and to inspire feelings of natural energy, vitality, youth, and vigor.

The main concept of the Taiho Oncology logo is that of vital energy, with an emphasis on the energy produced by Mother Nature. This refers to the natural energy that puts forth a tree, which then grows a robust trunk, extends a branch, makes a flower bloom, and then bears fruit. The logo also captures the harmony between earth and the sun—the source of all growth and vitality on earth. This is a symbol of vitality from ancient times.

The “T” represents the initial letter of Taiho, and the power of nature is expressed by the fact that the logo is hand-drawn.


Red is used to portray our company’s energy, vitality, and liveliness. The sepia (brown), an ecological color, represents human beings on earth and the intention of natural symbiosis. The yellow conveys that this is a new company, overflowing with youth and vigor.
