I'm a Japanese/Australian born in Kanagawa, Japan. A translator by trade, I hunt, breed, and show the Nihon Ken.
Is Ibuhime out of coat? That picture makes her coat look very short.
Yes, I heard she was out of coat at that time. However, the Choushun line does have shorter coats than the Hata line. I can see the difference here in my kennel when the dogs shed, especially comparing Bishoume and Kunitaka.
It's almost as if they were trimmed/shaved. Interesting to know.
