Basic Policy of Management

The Sumitomo Electric Group, in accordance with the Sumitomo Spirit and the Sumitomo Electric Group Corporate Principles, shall strive to be a group of companies worthy of society`s trust by conducting the business activities in an honest manner.

The Sumitomo Spirit

The Sumitomo Spirit grew out of the guiding principles set down by Sumitomo founder Masatomo Sumitomo in his "Monjuin Shiigaki" (the Aphorisms of Monjuin). This corporate spirit has been developed, deepened, and handed down over generations in the Sumitomo Family enterprise, and its essence was distilled in the Rules Governing the Sumitomo family established in 1882, and formulated into two business principles in 1891. Although there were some corrections to the wording, the Business Principles have been inherited with no change in the contents up to now.
