New user trying to use multiple amazon accounts

Hi

I'm a new user here. I came here because I'm trying to figure out a multilingual problem. I read in multiple languages, but my Kindle Paperwhite is registered with amazon.co.jp in Japan. This means I can only use DRM free books, or purchase them from Amazon Japan.

My goal is to open a second Amazon account with Amazon France, and someone get those books onto my Kindle and read them.

Someone pointed me to this DeDRM plugin:

But this is all new to me. Are there any like users out there who have figured out how to purchase books from various Amazon accounts (Japan, France, Mexico) and get them all on the same Kindle device?

Thanks in advance for any pointers including forums that are for this. :help::thanks:
