The origins of Sumitomo Chemical Company are deeply rooted in the Sumitomo Group, a prominent Japanese conglomerate. Its establishment in 1915 as a fertilizer plant in Niihama, Ehime Prefecture, was a strategic initiative by the Sumitomo General Head Office to mitigate environmental impact from copper smelting operations.

Genesis as a Fertilizer Plant Sumitomo Chemical began its operations in 1915 as a fertilizer manufacturing plant. This venture was a direct response to environmental concerns stemming from copper smelting activities. Environmental Solution The company's initial purpose was to convert sulfur dioxide emissions from copper smelting into valuable agricultural fertilizers. Incorporation as Independent Entity In June 1925, the chemical division was established as a separate company, Sumitomo Fertilizer Manufacturing Co., Ltd. This marked a transition from a division to a corporate structure. Public Investment The company's capitalization was increased through the sale of stock shares to private investors, indicating an early diversification of ownership. Name Change and Product Expansion In February 1934, the company's name was changed to Sumitomo Chemical Co., Ltd. This reflected an expansion of its product line beyond fertilizers to include industrial chemicals. Early Ownership Structure While specific details on initial equity splits are not readily available, the incorporation and share sales suggest an ownership structure that moved beyond sole control by the Sumitomo family.

The transition from a division under the Sumitomo General Head Office to an independent company, Sumitomo Fertilizer Manufacturing Co., Ltd., in 1925, was a significant step. This move allowed for increased capitalization through the sale of stock shares to private investors, broadening the ownership base beyond the direct control of the Sumitomo conglomerate. The subsequent name change to Sumitomo Chemical Co., Ltd. in 1934 further solidified its identity as a diversified chemical producer.
