Nitto Co.

What Nitto Co. does

Nitto Co. (株式会社ニットー) is a privately held Japanese precision surface-finishing service provider specializing in ultra-precision flat lapping and polishing of hard and brittle materials. Founded circa 1945 and headquartered in Suzaka City, Nagano Prefecture, the company operates a single, integrated manufacturing site that combines batch-type double-sided polishing, single-piece polishing, mirror polishing, and Chemical Mechanical Polishing (CMP). It serves industry-leading material manufacturers and parts manufacturers in Japan, processing glass, ceramics, resins, metals, and composite structures into substrates and components requiring tight thickness, parallelism, flatness, and surface roughness specifications.

The company's technical foundation rests on a fleet of over 100 lapping and polishing machines — including 18 large-scale double-sided polishing units capable of handling 500mm+ substrates, described as top domestic class in Japan — supported by Class 100, 1000, and 10000 cleanrooms and a full suite of measurement instruments (laser interferometers, confocal laser displacement meters, SEM, AFM, surface roughness meters). Competence is built on decades of accumulated process know-how: the ability to optimize abrasive grain, pad, and operating parameters across millions of combinations to hit customer-defined surface quality targets, including difficult-to-process materials such as silicon nitride via CMP. The facility layout enables end-to-end workflow — cutting, grinding, lapping, CMP, washing, and cleanroom inspection — without subcontracting handoffs.

Commercially, Nitto runs a sales-led B2B model: customers reach the company via multiple website inquiry channels (general, technical consultation, casual consultation, trial production request, proposal), receiving quote-based pricing with trial runs available from a single piece through to mass production. The company is privately held, has no disclosed parent, no funding rounds, no subsidiaries, and no international footprint beyond Japan. Recent activity centers on talent development — new graduate and mid-career hiring through Mynavi (2027 and 2028 cohorts), internship fairs, and short-form web information sessions — and on technical content publishing via its lapping technology blog. No AI/ML, software products, APIs, public listings, or partnerships are disclosed.

Core offering

Nitto Co. is a precision plane lapping and polishing contract manufacturer that performs ultra-precision flat surface finishing for materials including glass, ceramics, resins, and metals. The company offers trial production from a single piece through mass production, using 100+ polishing machines (including 18 large-format double-sided machines for 500mm+ substrates), Chemical Mechanical Polishing (CMP), Class 100/1000/10000 cleanroom inspection, and multi-stage polishing process optimization to deliver flatness, parallelism, and surface roughness quality to industrial manufacturers.

Product overview

Nitto Co. (株式会社ニットー) is a precision plane grinding (平面研磨) manufacturing service company specializing in lapping and polishing services for various materials including glass, ceramics, resins, and metals. Their core service offering is contract precision grinding加工 — they do not offer standardized software products or modules, but rather provide custom manufacturing services where they apply their grinding expertise to customer materials. Services include single-sided lapping, double-sided lapping, mirror polishing (鏡面研磨), and CMP (chemical mechanical polishing). They also offer prototyping (試作), material procurement, cutting/slicing, and grinding (研削) as pre-processes before lapping. Quality management includes cleanroom inspection (クラス100/1000/10000).
