Nippon Technart Inc.

Nippon Technart Inc. is a Japanese manufacturer of precision assembly tools and electrical test and measurement instruments, headquartered in Nakano, Tokyo, with a second site in Toda, Saitama. The company's name derives from the English phrase "state of the ART TECHNOLOGY," and its stated mission is to solve customers' problems with "art-level technology" — a positioning that frames it as a specialist engineering house rather than a mass-market tool vendor. The company's business is organized around two product pillars. The first is ultra-high-precision torque drivers, driver tools and controllers used for screw fastening where tightening torque must be controlled with extreme accuracy. Nippon Technart develops, assembles and sells its own-brand torque drivers, and its products are used in hard-disk drive assembly and watch assembly, applications where very small screws and tight torque tolerances are critical. The second pillar is electrical insulation and safety testing equipment: breakdown testers for evaluating insulating materials, lithium-ion battery separator insulation testers that use a proprietary impulse technique to detect metal-particle contamination, pinholes and scratches, automatic insulation/withstand-voltage testers, ultra-high-voltage withstand-voltage testers (up to 50 kV), and insulation resistance meters. The company also offers custom/contract development and standard radio-wave receivers. Nippon Technart serves customers in research and development, quality control and production engineering, and it emphasizes conformity with domestic and overseas safety standards. Its product literature highlights problem-solving themes such as over- and under-tightening of screws, fastening-data management, torque setting, narrow-pitch and multi-axis synchronized fastening, run-out countermeasures, static-electricity countermeasures, ultra-precision screws, screw floating, insulation breakdown testing, and reduction of production man-hours. The company is led by representative director Toyoji Kojima (小島豊司). It maintains a corporate site with sections on company profile, a message from the president, management philosophy, overseas expansion, access and recruitment, and it publishes news items on its homepage. Its headquarters and Control System Division are located in Nakano, Tokyo, while its Saitama office houses the Measurement System Division. The company presents itself as internationally oriented, with a dedicated "overseas expansion" section, and describes its products as evaluated as "world-leading" in demanding applications.

Nippon Technart Inc. is a Japanese precision-instrument company based in Tokyo. Its corporate name is explicitly derived from the English phrase "state of the ART TECHNOLOGY," and the company describes itself as a professional group that solves customers' problems through "art-level technology," supplying advanced technology and high-grade products. The company operates from a head office and Control System Division in Nakano, Tokyo (Yayoi-cho, near Nakano-shimbashi Station), and a Saitama office and Measurement System Division in Toda, Saitama (near Kita-Toda Station). The company's historical development is closely tied to two fields. In precision fastening, Nippon Technart developed its own-brand torque drivers and integrated development, assembly and sales in-house. Its torque drivers are used where ultra-high-precision tightening torque is required; the company states that its products hold the world's leading share in hard-disk drive assembly and are widely adopted for watch assembly. This reflects the broader Japanese precision-manufacturing ecosystem, in which suppliers of specialized fastening tools serve electronics and precision-device makers. In electrical testing, Nippon Technart built a portfolio around insulation evaluation and safety compliance. Its breakdown testers determine the dielectric breakdown strength of electrical insulating materials and are used mainly in research and development and quality control. Its lithium-ion battery insulation tester applies a proprietary method to detect separator insulation defects — metal-particle contamination, pinholes and scratches — in lithium-ion batteries, electric double-layer capacitors and lithium-ion capacitors, applying weak energy to minimize damage to the device under test. Its safety-related testers include automatic insulation/withstand-voltage testers that perform insulation resistance and withstand-voltage tests in a single unit, ultra-high-voltage withstand-voltage testers with a maximum test voltage of 50 kV and transformer capacity up to 2 kVA in a separate-type configuration that isolates the control section from the high-voltage generation section, and analog insulation resistance meters capable of external control and test-result output. Beyond standard products, the company offers contract development (受託開発) to realize customer requirements with advanced technology, and it manufactures standard radio-wave receivers with weather resistance and stable reception sensitivity. It also addresses production-engineering problems such as over- and under-tightening, fastening-data management and storage, torque setting, narrow-pitch and multi-axis synchronized fastening, run-out countermeasures, static-electricity countermeasures, ultra-precision screws, screw floating, insulation breakdown testing, and reduction of production man-hours. The company is led by Representative Director Toyoji Kojima. Its website includes sections on the company profile, a presidential message, management philosophy, overseas expansion, access and recruitment, and it publishes corporate news. The company presents itself as internationally oriented through a dedicated overseas-expansion section. No founding year, ownership structure or listing status is disclosed in the available evidence, so those details remain unconfirmed.
