Good Japanese copywriters are few and far between but they do exist. Translators and copywriters produce work that is worlds apart. Write copy, don't translate. Third, treating Japanese customers with less urgency and consideration than domestic customers. Domestic customer service staffs have a bad habit of de-prioritizing transactions from overseas.
Japan is too often out of sight and out of mind.
However, just like domestic customers, Japanese customers are in a hurry, need instant stock and order status information, and do not want any hassles even though they are shopping from overseas. Successful direct marketers treat their customers in Japan with the same level of urgency, expediency, and care as they would domestic customers, plus they go out of their way to systematically eliminate foreseeable problems that arise in international transactions. It's just like any other business, you have to sympathize with the customer's point of view to win. Fourth, believing the myth that you have to have a physical presence in Japan. Most service providers and consultants like to say that locating in Japan is a must, primarily because this increases their own importance and earning power.
