Our Corporate Identity (CI)

The CHIZAKI logo, a symbol of our corporate identity, is designed to visibly communicate the purpose of our business, unique management approach and other key concepts. Appearing as a dynamic object floating in space, the CHIZAKI logo represents the key philosophies underlying our operations in the 21st century.
The logo’s three stylized C-shapes stand for CHIZAKI, CREATION and CHALLENGE, indicating our awareness of the global environment and passion for the wellbeing of people everywhere. More specifically, the logo’s three elements symbolize CHIZAKIDORO’s creation of dwelling spaces that exist in harmony with nature and its determination to take on the challenge of achieving its corporate goals. Also, to more effectively convey our message we have employed our corporate colors: the deep CHIZAKI blue represents our intelligence, engineering and planning capabilities while dynamic CHIZAKI red expresses our enduring passion for innovative growth and achieving further expansion.
