I currently have a seller account in the United States.

From the Seller Central dashboard, I followed these steps:

'Global Selling' -> 'Japan' -> 'Create an Amazon.co.jp selling account' -> 'Start Selling Now.'

However, I am redirected to a page that asks me to select a seller and marketplace. The message says,

'Please select a seller and marketplace. You may be trying to sign in with a new device or have cleared your cookies. To get started, please select a seller and marketplace. You can change this selection anytime from the navigation bar at the top of the page.'

Additionally, when I try to register through the Amazon.co.jp seller account registration page (https://sellercentral.amazon.co.jp/home) while logged in with my US account, I receive the message: 'Unauthorized. This email address is not registered as a selling account.'

The options on that screen are 'Register' and 'Return to sign-in page,' but selecting 'Register' redirects me to the Amazon.com Seller Central registration page.

I would like to create a seller account specifically for Japan. Could you please advise on how I can create a seller account for Amazon.co.jp?
