It's been a while since anything Kai related went up on the blog, and since I was scraping around in my Kai files and doing a touch of research I thought I'd throw these up on the blog.
Mr.Yanagisawa was a extremely influential in the Kai as a breed from its very early days. While he lived in Nakano, Tokyo, he wrote many articles about the breed and worked hard to push for its preservation as a hunting breed. While he passed away a while ago, his family still runs the shop (at least they did last time I looked which was a few years ago). Mr.Yanagisawa had a famous male named Komarou who ended up being an amazing hunting dog. The dogs of his line were named after this dog, so are referred to as 'Komarou Kei' (Komarou Line).
Here's a few pics of three of the famous males, Komarou, Ichirou, and Gengorou.
