I'm using Method 1 Kindle for the Mac for both the Amazon Australian and Japanese store. I just realised that Mac doesn't let you have two versions of Kindle for Mac with two different stores on the same computer. Macs do allow you to have multiple versions of Kindle for Mac on the one computer but they will all open the one store. Has anyone worked out how to have two or more Kindle for Mac's on the one computer but registered with different stores?
Luckily I have two different mac computers so I can have one store on each computer but if someone knows how to have two stores on the one computer please let me know. I could keep on de-registering and registering I suppose...Not sure if its possible to have multiple copies on Windows either or if it only lets you have one copy on the computer...
