Department stores in Japan's Kansai region are experiencing a business boom, largely bolstered by the success of foreign trade. Reinforcing their international consumer base has emerged as a critical strategy for these businesses amidst fluctuating local market conditions. The rise in revenues signals the escalating globalization of Japan's retail sector and underscores the importance of overseas markets, particularly in large urban zones like Kansai.

In Japan, department stores are not just places to shop, but they represent a culture, housing a variety of businesses including high-end fashion, food courts, and more. Their success or failure is reviewed seriously. The fact that foreign trade is boosting these stores indicates a shift in Japan's consumer landscape. Japanese retailers are adapting their business strategies to cater to foreign tastes and demands to ensure survival and success.

In the US or EU, diversifying business and targeting overseas markets are common strategies. However, the level of dependence on foreign trade, especially in retail, seems higher in Japan due to its unique blend of local and international consumers. It's also reflective of the rapid growth of e-commerce, ICT goods and services, as well as shifting demographics and tourist trends in Japan.
