Company information
From a single pin to a jet engine, many of the things that surround us are "polished." When did the act of "polishing" objects, which is closely tied to human life, actually begin? The act of "polishing" is said to be a human instinct, with its origins tracing back to prehistoric times. Archaeological records indicate that the history of polishing began with Neanderthals in the early Paleolithic era, who used sandstone polishing stones to sharpen stone axes. It is also said that Japan has had polishing techniques for metal mirrors, needles, and magatama (comma-shaped beads) since ancient times, and since then, the world of "polishing" has continued to evolve alongside centuries of civilizational progress. Our company was founded in 1926 in Arakawa, Tokyo, later moved to Adachi, Tokyo, and in 1990 relocated our factory to Oshin, Shirakawa City (the complete relocation was finished in 2002), and we have continued to this day. We will contribute to the creation of a rich society by integrating the know-how and technology we have cultivated through the manufacturing of polishing materials. Please pay attention to "KOYO of Polishing."
