The language barrier is probably higher than you think in Japan. Many Japanese are shy in speaking English, and if they are forced to do so, they may give up ordering your merchandise in the first place. But it does not mean that they do not understand any English. Most of them, especially the younger generation, can read and write basic English. So, at least the orders and questions should be taken by fax, not only by telephone.
Fax is convenient from the point of difference in time as well.
If you can prepare the order form in Japanese, it would be better. In Japan, there are several laws and regulations for the sales and mail-order business, and you have to observe those laws and regulations. In order to avoid any possible troubles with Japanese consumers, this information should desirably be in Japanese. Japan Direct Marketing Association 1997, All rights reserved.
