The quality of Amazon Japan's Business Customer Service has deteriorated markedly from the situation that previously applied up until the middle of 2024 and to the extent that it is no longer possible to feel confident that issues, should they arise, will be dealt with efficiently and effectively. Previously Business Customer Service was very customer centric, efficient, courteous and effective, and freely available in English. Now English Language Support is almost impossible to obtain via chat and can only be obtained via email, lessening the efficiency of the Support Process. Yet Amazon is very happy to enable Business Accounts in Japan to be conducted in English. I have used Amazon Japan for over 10 years and whenever I needed assistance in the past, the experience was very positive. Now, however, this is no longer my experience. Huge, huge thumbs down to Amazon for whatever change in Japan it has recently made to its Japan Customer Service operation.
