[Sangetsu]

This law is designed primarily for Brazilian auto workers, who, for the most part, haven't seemed to want to learn or to speak Japanese. Most other workers in Japan do not stay for so long. Teachers get 1 to 3 year visas, as do most other professionals who work in the country. Most professional jobs require little Japanese knowledge, and as most assignments to Japan are usually temporary, there is no great need to learn the language.

Auto workers, on the other hand, often work in the factories for many years. For safety's sake, and for the sake of preventing a non-literate second class of people to develop, the visa plan is a good idea.
