两个不互通,需要分别注册哦,可以使用同一邮箱分别注册日本亚马逊和美国亚马逊,我就是这样的,中亚、日亚和美亚用的是同一个邮箱。各个国家的亚马逊网站账户是独立的,所以不会有冲突,但都需要分别注册。希望对你有帮助
The two are not interoperable, so you need to register them separately. You can use the same email address to register Amazon Japan and Amazon US separately. I did this, and I used the same email address for Amazon Central, Amazon Japan, and Amazon US. The Amazon website accounts of each country are independent, so there will be no conflict, but they all need to be registered separately. I hope it helps you
