Santen Pharmaceutical Co., Ltd. is a Japanese ophthalmology-focused pharmaceutical company founded in 1890 in Osaka. Its current corporate logo, featuring a symbolic design built around the initial “S” from Santen, was introduced on July 4, 1992, the company’s founding anniversary. The logo marked the first time Santen used alphabetical notation, a decision made in recognition of the expansion of its corporate and business activities on a global scale.[1]
Design and History
The 1992 logo consists of two large “S” shapes stacked on top of each other. According to Santen’s official account, the design expresses the company’s commitment to cutting-edge technology and strong growth. The upward movement toward the right signifies the company’s dedication to “Tenki ni Sanyo Suru” (Exploring the secrets and mechanisms of nature in order to contribute to people’s health), which is both the source of the Santen company name and its core principle.[1]
The company name “Santen” traces back to 1890, when founder Kenkichi Taguchi opened a private firm called Taguchi Santendo. Taguchi borrowed the Chinese characters “参” (San) and “天” (Ten) from a passage in a Chinese philosophical classic. The name has remained unchanged for more than 130 years.[1]
Meaning and Symbolism
The logo uses two shades of blue, officially named SANTEN BLUE and SANTEN DEEP BLUE. The lighter, fresher SANTEN BLUE serves as the corporate color and signifies the company’s commitment to providing clean, high-quality products.[1]
The stacked “S” design also carries a directional meaning: the movement pointing upward to the right toward the sky (“ten” in Japanese) reflects the origin of the company name and its founding philosophy of contributing to people’s health by exploring the secrets of nature.[1]
