Guiding Principles by Busaburo Otsuka
“Good product quality is the key to the operation of the factory, and packaging is part of product quality as well. We must produce and sell our products from the point of view of the buyers.”
This guiding principle was written by the founder Busaburo Otsuka (1891–1970), known as a superior calligrapher with a pen name of Otsuka Geppō, and familiarly known as “Oyaji-san” (meaning old man) by employees.
In 1946, with the company engaged in manufacturing and selling injection drugs, Busaburo wrote these guiding principles to clarify what his employees should do to ensure proper manufacturing, transportation, and sales: “Quality is vital in a factory and so is packaging. We have to manufacture and market, putting ourselves in the consumer's position.” Even today, the principles are displayed at the company's front entrance and at each plant. The philosophy of “Quality First” is deeply ingrained in each and every Otsuka employee.
Significance of the Corporate Symbol
A symbolic representation of Otsuka Group Corporate Philosophy, the corporate symbol adopts the initial “O” of the corporate name as its motif.
Representing the sky above, the large “O” is rendered in gradations of Otsuka BLUE intended to signify openness, freedom, intelligence, and future. The small “O” in Otsuka RED represents the focused energy of Otsuka, the wellspring of these tenets.
Offsetting the two forms poised in balance, the Otsuka name is spelled out in an open and friendly typeface. The corporate symbol conveys Otsuka group’s energetic commitment to human happiness through good health.
