Yajima Giken

What Yajima Giken does

Yajima Giken Co., Ltd. (矢島技研株式会社) is a Japanese factory automation (FA) equipment manufacturer founded in 1988 (incorporated as a stock company in 1991) and headquartered in Hikone, Shiga Prefecture, with administrative operations in Nagoya and a production facility in Nagano. The company designs, develops, and manufactures custom industrial automation and labor-saving machinery, including self-developed automated guided vehicles (AGVs) with a patent-pending proprietary control system achieving ±1mm positioning accuracy and double the tact time of standard AGVs, robotic welding line systems incorporating nut feeders, precision assembly equipment with sub-millimeter press-fit and clinching depth accuracy via inline measurement, and conveyance systems that integrate MUJIN image processing for bulk-material picking. Its technology stack combines mechanical engineering, servo-press and servo-nut-runner multi-axis systems, image-based inspection (including 0.001mm air-micro hole-diameter detection), and integration with third-party vision platforms.

The company's customer base is concentrated in the Japanese automotive supply chain, with named major customers including Denso (株式会社デンソー), Aisin (株式会社アイシン), Toyota Industries (株式会社豊田自動織機), Hitachi Astemo (日立アステモ株式会社), Advix (株式会社アドヴィックス), Chuyo Spring (中庸スプリング株式会社), and Metal Tech (株式会社メタルテック), alongside industrial machinery and electrical control component manufacturers. Revenue is generated primarily through one-time custom equipment sales, design, and integration projects, with pricing quoted per customer specification. The company sells directly through its three offices in Japan, targeting enterprise buyers via inquiry-based engagement.

In April 2024, Yajima Giken merged with Aitechno Yajima (株式会社アイテクノ矢嶋) to consolidate both firms' FA operations into a reconstituted Yajima Giken entity, while transferring the feeder business to parent company Yajima Kogyo (矢嶋工業株式会社). The company operates with approximately 24 employees and ¥10 million registered capital under Representative Director Ishikawa Kazuyuki (石川和幸), with no disclosed external funding, public listing, or international operations.

Core offering

Yajima Giken is a Japanese factory automation (FA) equipment manufacturer that designs, develops, and builds custom industrial automation and labor-saving machinery for automotive parts manufacturers and general industrial clients. Its in-house portfolio includes self-developed automated guided vehicles (AGVs), robotic welding line systems, precision assembly devices, and conveyance systems, with integration of MUJIN image processing for bulk material handling. The company operates from Hikone (HQ), Nagoya (admin), and Nagano (production), and serves tier-one Japanese automotive suppliers including Advix, Denso, Aisin, Toyota Industries, and Hitachi Astemo.

Product overview

Yajima Giken is an FA (Factory Automation) equipment manufacturer offering a portfolio of self-developed automation and labor-saving mechanical devices. The core offering consists of proprietary automated guided vehicles (AGVs) with patented control systems, robotic welding line systems, precision assembly devices, and conveyance systems — primarily serving automotive parts manufacturers and general industrial clients. The company's feeder business (covering nut feeders and peripheral equipment) is operated by its parent company, Yajima Kogyo Co., Ltd., following a 2024 reorganization in which Yajima Giken and Aitechno Yajima merged their FA divisions into a new unified entity.

• Epson: Epson's Robotics division supplies SCARA and other industrial robots widely used in assembly automation for electronics and small-parts manufacturing. It is comparable to Yajima Giken in targeting precision assembly automation, though with a different robot architecture focus.
• Kawasaki Heavy Industries: Kawasaki's Robotics Division supplies industrial robots for welding, assembly, and material handling across automotive and industrial customers. It competes with Yajima Giken for automotive automation programs but operates at much larger scale.
• Panasonic Connect: Panasonic Connect (formerly Panasonic Industrial Solutions) sells FA solutions including welding systems, sensors, and assembly automation. It directly competes with Yajima Giken in automotive welding lines and electronic-parts assembly, while operating at significantly larger scale.
• Yaskawa Electric: Yaskawa Electric is a global leader in motion control, servo motors, and industrial robots used in welding, assembly, and material handling. It overlaps directly with Yajima Giken's welding line systems, servo press, and assembly equipment categories.

Emerging players

• MUJIN: MUJIN is a Japanese AI-robotics software company whose image processing system is already integrated into Yajima Giken's conveyance devices. It is a technology partner and an emerging player in intelligent robotics, with overlapping customer use cases in bulk-pick and random-orientation handling.

Direct peers

• DAIHEN: DAIHEN manufactures welding equipment, welding robots, and FA systems, and is one of the closest direct competitors to Yajima Giken's welding line systems and automotive parts assembly automation. Both are mid-sized Japanese suppliers focused on welding-centric automation for automotive customers.
• Nabtesco: Nabtesco produces precision reduction gears and motion control components that go into industrial robots and automation equipment. It is a comparable Japanese specialist supplier of high-precision components feeding into the same automotive automation value chain as Yajima Giken.
