As a global chemical manufacturer, Tosoh's shareholder base is diverse, with significant holdings by financial institutions. Understanding this ownership structure is key to grasping the company's governance and strategic decisions.

Tosoh Corporation's origins trace back to its founder, Tokusaburō Iwase, who established the company as Toyo Soda Manufacturing Co., Ltd. in 1935. The initial objective was to produce sodium carbonate, a vital component for Japan's burgeoning glass industry. While precise details regarding the founder's initial stake or early investor allocations are not readily available, the company's foundation was firmly rooted in industrial development.

The external auditors provide an independent perspective, free from significant business dealings or investments in Tosoh, ensuring an objective review.
