OUR STORY
[ Value Creation Story ]
- Steadily Accumulating Value -
In 1950, TAIYO YUDEN started selling its first product, barium titanate tubular ceramic capacitors. This product was used as an essential component in radios, which were the leading form of entertainment at the time, and helped to bring enjoyment to people's lives. Later, our multilayer ceramic capacitors (MLCCs) and other electronic components have helped to advance progress in TVs, video recorders, CD players, PCs, mobile phones, smartphones, automobiles, AI servers, and many other kinds of electronic equipment. We have steadily built up value by working toward greater comfort and convenience for people and by addressing social issues.

[ Management Philosophy of TAIYO YUDEN ]
Employee well-being Betterment of local communities
Responsibility to provide returns to shareholders
Hikohachi Sato, the founder of TAIYO YUDEN, worked as a researcher in ceramic materials
before the second world war. Following the belief that 'product commercialization should start from the development of materials,' Mr. Sato launched TAIYO YUDEN to develop and commercialize titanium-oxide porcelain capacitors in 1950.
He also believed that affection for others was the most valuable thing a person could have. The Company's management philosophy has three major compo-
nents, all of which are designed to improve the social nature of the Company and contribute to cultural development by creating an environment in which employees and their families can live their
lives in happiness and prosperity.
The beliefs and philosophy of Mr. Sato live on as the underlying
spirit of TAIYO YUDEN.
