以臺灣與日本的經濟發展過程來看，自80年代以後，兩國可謂進入了經濟的高度成長期。然而，經濟的高度發展亦使兩個面臨了基層勞動力不足的問題。為解決此問題，於兩國國內均引發了外籍勞工引進與否的論爭。其結果，臺灣採行了開放門戶，大量引進外勞的「開國」政策，而日本卻維持特例來閉鎖門戶，少量引進外勞的「鎖國」政策。 在本研究中，正是以「鎖國」政策下之日本外籍勞工問題為探討對象。其主要論述內容包含日本外籍勞工之組成及形成背景，外籍勞工之存在意義，外籍勞工之就業現況等研究課題。

　　　　　The economic developments in Taiwan and in Japan have been approaching to the summit of economic growth since the 80'c. With the thriving development in economy, however, both countries have suffered the deficiency of labor-force at the basic level. To tackle this problem, both countries held fierce debates about the issue. What is worth noting is that they adopt decisive policies, respectively. The government in Taiwan opens its door to introduce the foreign laborers, whereas that in Japan closes its door and adopts Closed-door policies. In this research, we try to analyses on foreign laborer problems under the Closed-door Policies of Japan. Especially to discuss the problems about the composition, the meaning, and the employment of the present situation.
