1. purchasing behavior: individuals purchase goods from Japan and earn the difference. But this method has the disadvantages of high unit price and time-consuming and laborious replenishment. With the in-depth development of imported cross-border e-commerce, personal purchasing with small quantity and high price will be gradually eliminated, resulting in Japanese purchasing being cheap in Taobao.

2. Cost factor: Japan's commercial retail system attaches great importance to integrity and procedures. According to the previous wholesale procedures, Japanese brands will restrict a large number of importers in order to protect the interests of domestic lower-level wholesalers and retailers. However, with the popularity of cross-border e-commerce in China, Japanese brands have seen huge benefits, which has also shaken the previous retail system and made it cheaper to buy Japanese goods on Taobao.
