Nihon Exceed Corporation

Nihon Exceed Corporation is a Japanese company specializing in precision polishing and cleaning of semiconductor materials, oxide materials, compound materials, and metal materials. Founded in October 1946 and headquartered in Jōsō, Ibaraki Prefecture, the company has evolved from optical instrument manufacturing into a leading contract polisher for advanced semiconductor substrates. Its core expertise is encapsulated in its 'Five Ultra' technologies: ultra-flattening, ultra-smoothing, ultra-strain-free, ultra-cleaning, and ultra-thinning. These capabilities allow the company to process a wide range of crystalline materials, including hard-to-handle compounds such as SiC and GaN, to nanometer-level surface roughness and micrometer-level thickness control. Nihon Exceed operates two plants in Ibaraki—the main plant in Jōsō and the Moriya plant—and serves customers both in Japan and internationally. The company is privately held with capital of 85 million yen and is led by President Yosuke Ohashi. It has been recognized as a 'Vibrant Manufacturing SME' and a 'Regional Future Leader' by Japanese authorities.

Nihon Exceed Corporation traces its origins to October 1946, when it was founded as a company in Japan. In March 1961, it was established as Kawaguchi Optical Instruments Co., Ltd., a limited company, and in October 1963 it was reorganized into Kawaguchi Optical Instruments Co., Ltd. (kabushiki kaisha). In November 1966, the company built a factory in Kawasaki and relocated there, entering the field of silicon wafer polishing. This marked its transition into semiconductor materials processing. In November 1981, the company changed its name to Nihon Exceed Corporation. In December 1982, all operations were relocated to Mitsukaido City (now Jōsō City) in Ibaraki Prefecture, where the main plant was completed. The second plant was completed in August 1984, and the third plant in October 1988. In October 1995, capital was increased to 85 million yen. In June 2000, the Moriya plant was completed and began operations. The company obtained ISO 9002 certification in November 2000, ISO 9001 in November 2003, and ISO 14001 in October 2004. In March 2006, it was selected as one of the '300 Vibrant Manufacturing SMEs' by the Japanese government. In March 2009, it established a mass production line for hard materials (SiC and GaN). In March 2016, it expanded its oxide line and began production. In October 2020, it was selected as a 'Regional Future Leader' company. Today, Nihon Exceed continues to lead in precision polishing technology, serving the semiconductor industry with its 'Five Ultra' technologies.
