Recently, Japan has promoted its import policy with Korea to lower the surplus of international payments and settle severe foreign trade disputes. Therefore, industrial imports are rising sharply, accounting for $1.061 trillion, more than 50 percent of total number of import. This report reveals that according to the report released by the department of Japanese trade, the substantial proportion of product imports has a great influence on adverse imports from Japanese field companies through overseas direct investment, accounting for $429 billion, 95 percent, in 1986 to 1990.

Accordingly, Japan still maintains the current structure of import-led primary products to export-led manufactures. In other words, Japanese development has been fueled by trade with foreign companies rather than progressing overseas Japanese corporations.
