Citizen Micro Co., Ltd.
Who we are

Based on the ultra precision machining technology developed from manufacturing Citizen watch components, the motor business has developed and manufactured thousands of types of micro gear motors from 1964 to today. These unique products that combine micro motors under 35 mm in diameter that are the forte of Citizen with gear heads and encoders are renowned worldwide for their accuracy, performance, and reliability and area widely used as the drive mechanisms in a variety of fields including medical devices, industrial equipment, optical devices, and robots. We will continue the challenge of innovating micro gear motors to contribute to society and to become the foremost micro actuator producer in Japan and the world.

Our values

The Company was established in 1958 in the form of its predecessor entity Sayama Precision Co.,Ltd. in the eponymous city of Sayama in Saitama prefecture as the first watch part processing and manufacturing company of Citizen Watch Co.,Ltd.

The Company advanced into the manufacturer of micro motor decelerators using gear-tooth indexing technology derived from the Company's expertise in the ultra-fine machining technology of watch parts manufacture. In 1963, Koma Precision Co., Ltd. (Saitama prefecture, Hidaka city) was established, followed by Chichibu Precision Industries Co., Ltd. (Saitama prefecture, Chichibu city) in 1980. The inception of in-house motor development and manufacture connected to the creation of reduction-device equipped motors (geared motors) which were to become the industry-standard, marking the origin of the Company's motor manufacturing operations today.

Including the subsequent founding of Comatec Co., Ltd. through the merger of Koma Precision Co., Ltd. and Chichibu Precision Industries Co., Ltd., the consolidation of Citizen Watch Group companies in October 2013 gave rise to the current Citizen Micro Co., Ltd.

On October 1, 2018 respectively the 60th and 55th founding anniversaries of Sayama Precision Industries Co., Ltd. and Koma Precision Co., Ltd., the Company relocated its head office from Sayama city to Hidaka city. Moreover, following the resumption of operations at the Chichibu Factory in August, with the operations structure of the Hidaka Head Office Factory and Chichibu Factory the Company made a new step forward.

The transition and history of watch part manufacture accumulated since the founding days of the Company find expression in the motto Small but First Class as the Company continues to provide quality and services of excellence that meet the expectations of customers in the design and manufacture of ultra-precision molds, the machining, plasticity, and forming processes of smmallsize and precision components, and the design and manufacture of micro gear motors.

Today the motor types manufactured by the Company find application in a wide range of fields such as medical equipment, industrial equipment, housing accommodation and security equipment, and optical equipment, serving their purposes day after day hidden from people's eyes as they go about their lives. For all employees of the Company this has been a source of inspiration and encouragement to do their best.

True to its corporate Small but First Class,Citizen Micro Co.,Ltd. will continue to push ahead with the evolution and advancement of its proprietary micro core technologies, and with customer satisfaction as the overriding concern aim to be a company that takes up new challenges in the pursuit of ever more diverse fields in micro technology.
