Marudai Kiko Co

What Marudai Kiko Co does

Marudai Kiko Co (丸大機工株式会社) is a Japanese precision contract manufacturer founded in December 1975 and headquartered in Nikaho City, Akita Prefecture. The company offers total-solution manufacturing services covering mechanical design, electronic circuit design, software design (PLC/PC/microcontroller), large-scale precision machining (including 5-sided machining on tables up to 2,500×5,000mm), precision parts machining, welding/fabrication, cleanroom assembly (Class 4–5 cleanliness in constant-temperature factories), and on-site installation and calibration — all performed in-house across six specialized factories.

The company generates revenue primarily through project-based OEM and ODM contracts for semiconductor manufacturing equipment (harness assembly, soldering, sputtering, lens molding), industrial machinery and factory automation customers, and automotive and medical-device manufacturers. A secondary, smaller revenue stream comes from self-developed proprietary products such as the FB-150A automated fireworks shell paper-wrapping machine and industry-academia co-developed products including the Ubiquitous IV Stand Cover (with Akita University) and the CP-01 Cell Stamper (with Akita Prefectural University). Marudai also provides professional technical services including on-site installation, calibration, and adjustment.

Go-to-market is direct enterprise B2B sales targeting Japanese manufacturers, with no retail or e-commerce channels, no publicly disclosed pricing, and quotes issued per project specification. The company is privately held with no disclosed external investors, listed registered capital of ¥500 million, FY2025 net sales of ¥6.17 billion (up ~20.5% YoY), and 289 total employees as of April 2026. Leadership comprises Chairman Masatoshi Shibuya (渋谷正敏) and President Kenji Kikuchi (菊地兼治). Government designations include METI Regional Future Traction Enterprise (2017), METI 300 Leading SMBs (2019), Akita Manufacturing Core Enterprise (2019), Akita SDG Partner (2021), and the 58th Good Company Award — Excellence Award (2024); ISO 9001 (2016) and ISO 14001 (2008) certifications are held at the headquarters factory.
