You can pre-order them from animate-onlineshop.jp but you will need some sort of shipping proxy to do so.
If you want to pre-order them you can buy going here.
If you buy all four from animate-online shop you will get a CD storage box while stock last. Amazon JP hasn’t currently listed any sort of bonus item just yet.
brave heart~LAST EVOLUTION Version~ by Ayumi Miyazaki which will cost and will be released February 19th 2020.
Beyond by Ayumi Miyazaki and will be released February 19th 2020.
At the moment I can only find those two CDs being listed on Amazon JP as of now.
