About manufacturers

A manufacturer is a company that produces products. In Japanese, these are sometimes referred to as “Makers” or “Seizogyo.”
Manufacturers can also be subclassified according to the products they make such as automobile manufacturers, food manufacturers, and apparel manufacturers. A wide variety of manufacturers exist in Japan.
Depending on the size of the company and the products made, one manufacturer may handle the entire manufacturing process from material manufacturing to assembly. But this is often difficult.
For example, the automobile industry is subdivided into three manufacturers; manufacturers that produce raw materials for vehicles such as iron and copper, manufacturers that produce car parts using those raw materials, and manufacturers that assemble parts into finished products. The process of completing goods in this way can be further divided into “upstream industries,” “middle-stream industries,” and “downstream industries” like the flow of a river.
The work contents of manufacturers varies. In addition to “production workers” who actually make products, there are also “sales staff” who sell products to customers, and “production management” that manages product quality and production volume. There are also jobs such as “product planning” and “research and development” for developing new products, and “advertising / public relations” that publish product information.

About manufacturers An industry that proactively hires international students

Manufacturers are companies that make things. Japanese manufactures are currently proactive when it comes to hiring international students. International students are expected to strengthen and diversify companies for expanding overseas.
In terms of the ratio of companies hiring international students (by industry), 52.2% of the companies classified as manufacturers employ international students (Ministry of Economy, Trade and Industry survey from March 2015).

On the other hand, for trading companies, which are often compared with manufacturers, this is 24.3%, so manufacturers are recommended for international students who want to find employment in Japan.
