I've noticed some ukiyo-e artwork in the following games:

-Fatal Fury Special
Jubei's Stage, screen panels decorated with women, most likely by Kitagawa Utamaro

-Last Blade 2
Akari's win pose, the lantern ghost (serving something to drink - couldn't identify - it's fun to see him in this role), by Katsushika Hokusai
Akari's "super finishing move", the cat with a starfish patternd fabric on the head, by Utagawa Kuniyoshi (very famous for his warrior prints - musha-e - and always a good inspiration for SNK Staff, as seen in Last Blade and samsho)

Any more? Sure!!! Anyway, what does this freaking lantern ghost serves to akari, anyone knows? Whoooooouuo...I suggest grappa del piemento!
