Aiming for a future where Japanese manufacturing creates the world

About Proto


Great because it takes time

We perform integrated production from aluminum casting to processing, and specialize in manufacturing various industrial parts.
We can cover not only prototypes of small lots (from one unit) but also mass production / assembly and mass production of final products.
We will continue to propose various solutions based on the concept that "means for solving problems are required, not prototypes or products themselves."

About employee development


Companies and people grow by working as a team

Acquiring skills is not something that can be done immediately.
Proto recommends working in teams to develop individual skills.
By doing so, there is a mechanism that synergistically enhances the quality of organizations and services.

Working companion


Work in the 20s and 30s is the mainstream and finds rigor and rewarding

Prototypes are manufactured in a variety of small lots with different drawings for each part type.
It takes time and the materials provided are not the same.
Each time you work in an environment where you encounter and think about problems and where people grow with your products.
t is not an easy job, but we are aiming to create a good environment where younger generations can speak and play an active part.
