My favorite deck is the 'Tarot of the Samurai'. The artwork is a little hokey to me, because I know what a properly worn kimono looks like, and how a proper 'chon-mage' (the stereotypical samurai hairdo) looks. The artwork is a bit too cartoony for my liking, but the backs of the cards are a very pretty ukito-e print whose name escapes me at the moment XD lol. I like that it gives the interpretations as poignant little phrases rather than keywords or overly specific stuff.
Also, the court cards are inspired by legendary and/or historical Japanese figures.
