The present study presents several suppositions regarding the conditions for success in Japanese market on the basis of research done on korean corporations. The summary of such analysis is as follows. First, the common factor among successful korean corporations in Japan in the aspect of business environment is the distribution strategy. Like the `eisan` case presented in the study, until its business with Sony, it kept abnormal dealings for a long time with the existing business partners because of the general practice. Second, regarding the research on the characteristics of Japanese consumers, results reemphasized the past research results. However, it was revealed that in addition to the consumers` prudence leading to the decision of the purchase, they tend to regularly use the purchased item for a long time. Third, the corporations that succeeded in the beginning approached preferentially the more accessible market. Amongst the cases in the present study, GOSEI proceeded with such caution. It ventured into the market targeting korean residents in Japan before expanding to various other markets in Japan. Fourth, in view of the strategy regarding business environment and managing resources, the importance of learning mechanism has been set in new light. It is not easy even for a product that has been recognized its superiority to be met with the expected fervor by the Japanese consumers. In conclusion, in order to succeed in Japanese market appropriate establishment of distribution channel and accurate understanding of consumer`s taste must be acquired. Government`s efforts toward stronger and wider collaboration between the two countries` corporations would be ideal.
