The japanese Yakuza Kiwami cover is surely not one of the best, it's a little plain compared to the beaufitul arts we've seen in the series on both japan and western relases.
But I find a wonderful official artwork that could be used as a perfect cover for the western edition of Yakuza Kiwami.
The artwork comes from a Famitsu Cover (don't remember the number but I can provide if needed).
I just did a quick mock up to give an idea of a possible final result with all the logos:
The art is probably done by Sega Japan (so there shouldn't be problems to use) and it's perfect fit to stand between the colorful covers of Yakuza 0 and Yakuza 6, and it would probably stand out much more in the store shelves.
In comparison this is the original japanese cover of Yakuza Kiwami:
what do you think?
Sega Atlus please consider my humble suggestion, thank you.
