Recently, something has been going on with Amazon Japan. I may plan on ordering from there sometime soon (It will be a couple more customs I'm gonna do).
This is the bug I've been getting on checkout recently (It doesn't matter if it's in stock or out of stock):

It's crazy to see this happen.
Sometimes, my cart fully resets. I never see this issue happen before. I hope it gets resolved soon.
