The job of making car parts is very important. This job is an integral part of the automotive industry and involves the production of various parts and components for cars.

Specific tasks include machining metal, molding plastic, and assembling parts. The work requires the use of state-of-the-art technology to produce high-quality, reliable parts.

Attractiveness and Opportunity to Work in Japan

Japan is home to many of the world's leading automakers. There are various automakers that you have heard of, such as Toyota, Honda, and Nissan.

This is why there is so much attention paid to technology and quality, and the brand value of "Made in Japan" is recognized. Working in such an environment, engineers not only acquire great skills and knowledge, but also have many career opportunities in the future.

In addition, the number of people working in Japan is decreasing due to the fact that there are fewer children and an increasing number of elderly people. This is why expectations for foreigners are increasing, and the government is promoting a "multicultural society.

What Do You Do at a Job Making Auto Parts

A car is made up of an amazing number of parts. Depending on the model of the car, there can be as many as 20,000 parts or more assembled together.

When we make cars, we often use a conveyor system. This is a system in which various operations are carried out in sequence according to the machining procedure, and the work is carried out in motion throughout the process.

The main steps in the process are "processing," "assembly," and "inspection. These steps are repeated to complete the final product!


Manufacturing and processing are performed using equipment and tools. For example, press work is required to produce metal parts such as bumpers and doors. In this process, metal is set in a machine and pressure is applied to change its shape.

The material used is not only metal, but also resin (plastic) is sometimes used. The mold is used to shape the part into a specific shape, which is then cooled, hardened, and finally removed from the machine.


In assembly, manufactured parts are smoothly combined to make automobile parts.

Since large parts are assembled by many people working together, it is necessary to communicate with each other and concentrate on the task at hand.


Inspection is an important part of making automobile parts. Quality is checked by checking how firmly welded parts are attached, whether the paint is well applied, and so on.

Some factories use automatic equipment for inspection, in which case we operate the equipment. But if a defect is missed, the car itself may be recalled, which is a big problem. So inspection is an indispensable step.
