Sumitomo Riko Company Limited traces its origins back to December 1929 in Yokkaichi-shi, Mie, Japan, initially established as Showa Kogyo Co., Ltd. The company's foundational business was the production of rubber belts. A year later, in 1930, its name was changed to Kabata Chotai (Belt) Co., Ltd., reflecting its core product. The trajectory of early ownership and strategic direction saw a significant shift in 1937 when the company became part of the Sumitomo Group, leading to a renaming as Tokai Rubber Industries, Ltd. This integration was a crucial turning point, aligning the company’s operations and future growth with the expansive Sumitomo conglomerate.

While specific details regarding the names of individual founders or their initial equity stakes at the company's inception are not publicly available, the rapid sequence of name changes and its eventual incorporation into the Sumitomo Group suggest an early ownership structure that was more corporate than individual-centric. The Sumitomo Group served as the primary early supporter, providing essential foundational backing and strategic guidance, deeply rooted in the Sumitomo Spirit, which emphasizes integrity and sound management practices. There are no readily accessible records detailing specific early ownership disputes, buy-sell agreements among founders, or founder exits during this initial period, as the company's development became intrinsically tied to the Sumitomo conglomerate's overarching vision for the industrial rubber products sector.
