The symbol-mark of "SK", designed using Roman alphabet initials of "SanKyo" is meant to "Safety" and "Know-how" (the ability required to form the expertise thing). There is no way that expertise and safety respectively intended to be pursued separately, both are always two sides of the same coin. We pursue the ultimate technology and the spirit of innovation, and we believe that it is the Safety itself. The two characters of S and K also include the third meaning which is the improvement of Service required for the company in the future, and the fourth meaning which is the accumulation of Knowledge.
