Hayashi Tokei Kougyou Co., Ltd.

We are a manufacturer of precision machinery and equipment that also handles original products.

We are a manufacturer of precision machinery and equipment founded in 1930. We mainly manufacture and sell LED lighting equipment, electric screwdrivers, and cooling units. We have been accumulating know-how on precision machines and tools since our foundation, and we receive consignment orders. These include semiconductor assembly for optical and microwave communications, optical fiber terminal processing, wristwatch assembly, microscopic examination, thick film printing, clean washing, and HDD/SSD screening endurance testing and breakdown study. We also manufacture in-house products such as Lumina Ace illumination for microscopes, Hi-Matic torque-controlled micro-screw electric screwdrivers, and a cooling unit using a Peltier element.


Sales Pitch

Our company excels at micro assembly.
Thick film printing and sintering
Our company prints thick films, which is currently rare.
We can also conduct leak tests.
Semiconductor assembly, prototyping, mass production
Our business is assembly and mounting on semiconductor packages, which is becoming rare in Japan.
There may not be many companies engaged in this work.
Microscopic work
There may be few companies doing micro inspection and assembly in a cleanroom.

Other presentation

[Company strength]
All of our manufacturing units provide support from trial manufacturing to mass production, including in-house products (LED lighting equipment, electric screwdrivers, cooling units, and so on). We can also perform die manufacturing and automated assembly in-house. Each unit has its own technology strength, such as processing technology, semiconductor assembly technology, electric design and mechanical design, and so on. We have an advantage in assembly and inspection in cleanroom using a microscope.

[Business description]
Our company was founded as a wristwatch assembly factory (we have celebrated our 85th anniversary). We are now expanding our business by pursuing our original technology in each business unit, with a focus on our in-house products (LED lighting equipment, electric screwdrivers, cooling units, etc.). We have advantages in precision assembly and precision processing, which we have been cultivating since our days as a wristwatch manufacturer.

Precision machinery and equipment manufacturing

[Strength of products/technologies]
We developed our in-house product Lumina Ace as illumination for microscopes in our days as a wristwatch manufacturer. We have also marketed the Hi-Matic torque-controlled micro-screw electric screwdriver, and a cooling unit using a Peltier element. We possess manufacturing units in the Tohoku region and overseas, which contributes to cost-cutting in manufacturing. 

[Representative's message]
“Now is the time to enhance our group’s comprehensive technology power and promotion power in the market, and practice creative destruction (innovation) with the courage to invent new enterprise value.” This is our group’s corporate slogan for this year. Our goal is to advance market cultivation, overseas expansion, and enlarging our business.

[Company structure for market development/overseas expansion]
Each business unit in our company, and particularly the precision assembly and precision processing units, pursues its original technology and develops its own business. We actively participate in various exhibitions to advertise products and collect customer needs in order to develop the market for our original products. We have set up a sales base in Hong Kong, and a sales base and consignment processing company in China (Shenzhen). We are expanding our business bases to Southeast Asian countries such as Thailand, Malaysia, Singapore, the Philippines, and Taiwan centering on our base in Hong Kong.
