The uncensored Japanese edition came with two stickers on the front; one Japanese game award from 2018, and a sticker advertising included DLC and the reversible cover insert. Inside the box there is a manual, DLC sheet, and an online survey card with a Devil May Cry 5 advertisement on the back. The game retailed for 8580 JPY.
A download code was supplied on an included sheet for Chris and Jill models of the Samurai Edge. It expired on 2019.06.25.
Supposedly the reversible cover was a first print exclusive, or exclusive to the more expensive editions. However, all copies seem to have the reversible cover.
First come, first served copies sold by e-Capcom came bundled with a masking tape wrapped in a plastic sheet and sealed with a paper sticker, resembling an ink ribbon. There were four variants, but only one was included with each game, selected at random.
