I still don't quite understand the application of this ban, I was able to order
https://vgmdb.net/album/73688 (avex classics) through amazon.co.jp and it didn't do any geo-restriction and let me place the order. We'll see if they actually ship it or not. That same album, along with every other avex * album isn't even available on CDJ, though you can tell they still have them in their database because 1) you can see the entry on neowing.co.jp 2) if you search for a banned product, the "similar products" footer still shows things related to it. For example if you search for AVCL-25956 on CDJapan, the footer shows Takayuki Hattori [artist] and Doraemon [series] as things you can subscribe to.
This has got to be the dumbest and most inconsistently applied export ban ever.
