We support your local and overseas sourcing with Japanese-style quality control and a robust domestic and international procurement network built over more than 90 years.









We offer a wide range of fasteners—including screws, bolts, and nuts—covering standard sizes, specifications, and various international standards.
Custom-made and semi-custom parts based on drawings are also available, from small lots to precision machining.
As an authorized distributor, we supply special components and related parts from partner manufacturers, ensuring stable supply and reliable quality.
Many of the fasteners used were JIS-standard products imported from Japan, resulting in procurement costs far higher than local market prices.
By leveraging our extensive overseas sourcing network, we proposed switching to overseas-manufactured parts, leading to a significant reduction in component costs.
Previously, parts were imported from the Japanese parent company, with 100% visual inspection conducted in-house.
By proposing a shift to local procurement, we reduced component costs and also took over inspection processes, contributing to lower indirect procurement and quality-control costs.
Direct transactions with local suppliers had caused chronic delivery delays, forcing bulk purchases and resulting in excess inventory.
By maintaining price and quality standards while enabling weekly deliveries of required quantities, we helped improve inventory control and reduce overall management costs.
We are a Japanese-owned company engaged in the manufacturing and sales of various metal-processed products, including screws, machined parts, cold heading, hot forging, press work, and forming.
Combining the technical expertise of a manufacturer with the sourcing and proposal capabilities of a trading company, we support a wide range of customer needs. Our Vietnam base is located in the Long Duc Industrial Park, Dong Nai Province.
