Core Principles

At Sumitomo Chemical, we are guided by our core principle that we must not only seek business profits but that we must contribute broadly to society through our business activities. This “Sumitomo Spirit” is based on the guiding principles of Masatomo Sumitomo, a Buddhist monk and the 17th century founding father of the House of Sumitomo, who urged family members to conduct business with honesty, prudence, and certainty.

Sumitomo Chemical’s core principles are clearly expressed in our Business Principles (established in 1891), our Business Philosophy, and our Corporate Statement.

The Sumitomo Spirit: Sumitomo’s Business Principles

  1. Sumitomo shall achieve prosperity based on a solid foundation by placing prime importance on integrity and sound management in the conduct of its business.
  2. Sumitomo’s business interest must always be in harmony with public interest; Sumitomo shall adapt to good times and bad times but will not pursue immoral business.

Sumitomo Chemical’s Business Philosophy

  1. We commit ourselves to creating new value by building on innovation.
  2. We work to contribute to society through our business activities.
  3. We develop a vibrant corporate culture and continue to be a company that society can trust.

Corporate Statement

Sumitomo Chemical started business in 1913 as a producer of fertilizers from sulfur dioxide gas emitted by copper smelters. This business, which solved the environmental problem of air pollution while meeting the social demand for more agricultural production, embodied the business philosophy of the Sumitomo family handed down from the 17th century.

“Our business must benefit society, not just our interests.” Throughout our history of almost a century, we at Sumitomo Chemical have lived by this credo. We have worked to build better lives by developing various businesses that meet people’s evolving needs. At the same time, we have continuously delivered technological innovation while paying special attention to product quality, safety, and the environment.

Looking to the future, we will create new value beyond the boundaries of chemistry by combining a variety of ideas, views, and technologies. We will also continue to take up the challenges facing the globe, from meeting basic needs, to protecting the environment, to addressing the issues of adequate supplies of food, energy, and other resources.

In this endeavor, each of us at Sumitomo Chemical will work together to enhance our capabilities, explore new possibilities every day, and overcome the challenges lying ahead with enthusiasm and a strong sense of mission.

Sumitomo Chemical will seek to continue to build trust and bring joy to people across the world through constant innovation.
