Since their founding in 1885, Fujikura has contributed to betterment of society by providing advanced technologies backed by uncompromising reliability. Their strength in the past has been a highly stable business built on strong partnerships fostered with a number of blue-chip customers. However, the markets upon which the future survival of Fujikura depends lie in the highly competitive global arena. However, in order to not only survive but also win in this market of constant and dramatic change, it is necessary to fundamentally reform their corporate culture. To achieve this objective, they have formulated the "Mission, Vision, Core Values" in August 2005 to be shared by all Fujikura Group employees - a new set of business principles that will help us successfully navigate a new and successful course through their reformation and the Third Era. Since then, the competitive environment surrounding their group has continued to become ever more intense and they have determined that they need to step up their reform efforts in order to build a stronger corporate structure that will enable us to maintain high profitability and achieve sound and stable growth. With this in mind, they formulated the 2015 Mid-Term Business Plan and, in a related development, the previously formulated corporate philosophy, "Mission, Vision, Core Values," was publicly re-established in October 2011 as the Fujikura Group Corporate Philosophy. This was carried out to encourage all group employees to join forces under a set of shared principles and work together to enhance their corporate strength.
