Japan is a high speed operation and a teamwork demanding society. The concept of the industrial chain reflects not only in society but also in the enterprises (especially the large ones). Therefore, because of the language ablility, that one could not communicate the information with the people around, will no doubtly give a strong affection on work progress and also cause the pressure of work and trouble on others. This is the first reason why Japanese company do not like make employment of foreigners.

Secondly, if you take a careful observation on some Japanese SMEs, you will find that the ambition to work in Japanese big companies remains entrenched, so for small companies, it is hard to obtain the outstanding Japanese talent. Objectively speaking, the vacancies in this community offer a lot of chances for foreigners to find jobs. Although some Japanese aliens may not yet know Japanese, but as a company operating technology development man, the company can compromise with this. From the long-term plan, it is important that look at how long this person is willing to stay in Japan. If it's only three or four years, many companies will refuse the foreigner, especially for those highly technical company. And this perhaps relates to Japanese companies' residual lifetime employment system as a custom.
