This is a good era to discuss any cat breed because it is before the recognized cat fancy and it taps in to the long history of this cat breed before photographs of cats were seen. What interests me is the appearance of the cat in these paintings compared to the appearance currently. At the time of this painting the Japanese bobtail had been in known existence for some 800 years. I have discussed the history on the Japanese bobtail page.
I am sure that the cats in the painting below are both bicolor and tricolor. I have marked the tricolor cats with red connecting lines to show what I think is the same area of color. The cats in the top right hand corner and bottom left hand corner of the picture are bicolor Japanese bobtail cats. The bicolor and tricolor were and remain the favorite types of coat for this breed in Japan.

I think the pictures make a nice comparison and the only real difference between the old and modern Japanese bobtail is that the old one is much more cobby (stocky) if the depiction is reasonably accurate. The modern breed standard states in my words that..:
If the body conformation is "cobby" (like a Persian or a Manx cat for example) then the cat will be penalized in competition.I would suggest that the cats depicted by Kuniyoshi Utagawa in this painting Four Cats In Different Poses, would all be penalized in competition and not win a thing in the show ring today.
It seems as if the modern breeding program has gone for a more “foreign” (slender) appearance (see Cat Body Types) and drifted away from the original appearance. The modern Japanese bobtail should be long, lean and elegant with no cobbiness according to the CFA breed standard. If I am correct and I am speculating, the cat fancy in the USA has refined this cat breed to make it more delicate looking (refined looking if you like) and attractive by modern standards. This is in line with what has happened to the Siamese cat and indeed other breeds (see Siamese cat history).
The Persian went in the other direction becoming excessively rounded including a very flat face (see Persian cats).
One last thing. The cat that is bottom right of the painting is waving the classic welcome with the palm of the paw outwards. This is the welcoming cat beckoning - the Maneki Neko ("Beckoning Cat"). The beckoning cat is placed outside shops etc. to bring good luck.
