We pursue high product accuracy and perfection by uniting precision machining and polishing technologies.

We have established an integrated production system from material processing to final finishing by linking up with the surface treatment business. Our high-grade watch casings have a 30% share of the market in Japan. We participate in overseas expositions and promote sales to manufacturers of European brand products. We are also developing new fields of business in medical instruments, equipment, and devices. We have experience conducting joint research with Tohoku University Graduate School of Dentistry and the College of Engineering, Nihon University.

[Company strength]
We provide products merging precision metal working and our corporate culture of beautiful Monozukuri craftsmanship as value for our customers. We have advantages in cold forging, high-accuracy machining, and decorative and functional polishing unique to our company. These are core technologies we have accumulated in manufacturing watch casings since our foundation. We have established an integrated production system from material processing to final finishing by joining up with the surface treatment business.

[Business description]
Our company was established in 1921. We have three main lines of business:

We are also extending our business to manufacturing medical equipment, implant implements for plastic surgery, and automotive parts.

Metal working

[Strength of products/technologies]
The watch casings we have been creating since our foundation require not only accuracy, but also quality and beauty. We have unrivaled high-accuracy forging and final mirror polishing technologies as the sole specialist manufacturer in Japan. Our new basic technologies are special anodic oxidation (AL ADVANCE), alumite treatment for thick and hard films, and nitrogen absorption (Pure Bright). These epoch-making technologies provide nickel-free ferrite stainless steel corrosion resistance equivalent to austenite and with greater hardness than martensite.

[Representative's message]
Our company has been manufacturing high-grade watch casings since its foundation in 1921. Our manufacturing technology is highly appreciated among manufacturers in Japan. We have demonstrated our technical power in various expositions and fairs and have been promoting sales to brand product manufacturers in Europe to exploit overseas sales channels. We are actively developing our new field of medical instruments, equipment, and devices. We provide “Made In Japan” products following the corporate philosophy “Make Good Things.”

[Company structure for market development/overseas expansion]
We have a business development group in the management administration department of the head office to acquire new customers and extend our sales channels. If new technical development is necessary, this group will cooperate with the merchandise development group, which has Monozukuri craftsmanship functions. We will also use public cooperation systems to promptly meet customer needs.
