I want to help you with this so been searching online for minutes now trying my hope to fix this for you. Some articles are saying they tend to lock your account for "security purposes" meaning you're buying too much and Amazon themselves are thinking the credit card could be stolen or not your payments. If you are totally locked out of your account cannot logon you need to submit a plan of action from the main email address on the Amazon account

[quote.]The plan of action needs to. address think caused Amazon to close your account. . You need to do a self-evaluation trying figure out why Amazon had a problem with your selling privileges. Sometimes the issue is easy to discover. Sometimes the issue is harder to figure out.You could make ya new Amazon Account set it up as Japanese then turn the language to English maybe if you want to go down that path?


If you find it easier just contact support via telephone. I wouldn't email as it takes days even weeks for one simple reply I find.
