KDDI is a Japanese telecommunications company formed in October 2000 through the merger of DDI, KDD and IDO. Its corporate logo, introduced at the company’s founding, is a bold uppercase wordmark in a deep blue known as “KDDI Blue,” with an arc sweeping across the lettering.
Design and History
The KDDI corporate mark was designed by Fumi Sasada of Bravis International, a brand consultancy that was selected to create the identity for the newly merged company in 2000. Sasada had previously designed corporate symbols for Japan Airlines, JTB and Morinaga, among others. [1]
According to Bravis, the bold uppercase logotype was intended to identify KDDI as a major player in its industry. The arc sweeping across the name resembles the curve of the earth seen from space, evoking a borderless world of international telephony and mobile communications. [2]
KDDI’s brand slogan has changed several times since the company’s founding. The company launched in 2000 with the slogan “Designing The Future,” renewed it to “Tomorrow, Together” in 2019, and adopted “Spark Your Journey” in May 2026. [3] The current corporate logo guidelines include versions with the slogan “Spark Your Journey” displayed alongside the KDDI wordmark. [4]
Meaning and Symbolism
KDDI Blue was chosen for its associations with futuristic high-tech on one hand and solid reliability on the other. [2] Contemporary reporting at the logo’s unveiling described the color as evoking futurity, high-tech and space, while the thick, stable letterforms expressed reliability and reassurance. The arc within the mark was said to represent the earth, information communication and the unity of the three merging companies. [1]
KDDI’s official brand guidelines define KDDI Blue with the specifications PANTONE 2747C, CMYK C100% M90% Y0% K32%, and RGB R14 G13 B106. [5]
