Masuda

What Masuda does

Masuda Corporation (株式会社マスダ) is a privately held Japanese precision-manufacturing company founded in 1962 and headquartered in Miyada-mura, Kamiina-gun, Nagano Prefecture. Under founding-family ownership led by President Hiroshi Masuda (増田 博), it operates as a Tier-2/Tier-3 contract manufacturer of ultra-precision components for medical and optical equipment OEMs. Registered capital stands at ¥15 million, and the firm holds ISO 9001 quality and Eco Action 21 environmental certifications.

The company's core capabilities span seven technology lanes: precision cutting and EDM, brazing and micro laser welding, pipe bending and metal forming, optical equipment assembly, precision sheet metal, laser marking, and a separate Miyada Tofu Workshop food business. Manufacturing is anchored on sub-millimeter tolerances — ø0.05mm micro-drilling, ø0.1mm wire EDM, and ø0.1mm laser welding spots — supported by hydrogen furnace brazing, 50+ CNC lathes, 20+ machining centers, and KEYENCE measurement systems.

Masuda serves a concentrated enterprise customer base that includes Olympus Corporation (a global endoscope leader), Evident Corporation (formerly Olympus Scientific Solutions), and Beckman Coulter Mishima. Production runs across two sites — the Nagano headquarters with approximately 237 employees and INA MICRO OPTO in Cebu, Philippines with approximately 240 employees — forming a Japan-quality, offshore-cost dual-sourcing model that also provides business-continuity redundancy. Revenue mechanics are B2B contract manufacturing with small-batch, high-mix flexibility suited to regulated medical-device supply chains.

Revenue model

1. Precision Parts Manufacturing: B2B manufacturing services for precision components used in medical devices (endoscopes, surgical instruments) and optical equipment (microscopes, industrial endoscopes). Revenue generated through production contracts for precision cutting, EDM, welding, pipe bending, sheet metal processing, and assembly services. Primarily long-term stable orders from major medical and optical device manufacturers.
2. Optical Assembly Services: Assembly services for optical equipment centered on microscopes and industrial endoscopes, adding value through complete product assembly rather than just parts manufacturing.
3. Food Products (宮田とうふ工房): Production and sales of tofu and soybean products using local Nagano Prefecture soybeans and water from the Central Alps. Operated as a separate business unit with its own retail presence.
