For instance I've got 6 full generations of Gakuhou here https://shikokuken.pedigreedatabaseonline.com/en/Gakuhou-Go-%E5%B6%BD%E5%B3%B0%E5%8F%B7/pedigree/42/i
And for kicks, I've connected the dots all the way through to the father of the Choushun line https://shikokuken.pedigreedatabaseonline.com/en/%E9%95%B7%E6%98%A5%E5%8F%B7/pedigree/618/i
So here we are at the very beginning of the breed. I was pretty excited when I realized I had an unbroken line of data all the way to Choushun.
I've currently got just over 600 dogs entered. My short term goal is to get 10 generations of data entered for all my dogs, and my friend's dogs. I'm contemplating crowdfunding this, since it is costing me a fair bit to create and maintain this site, and it's now very time consuming to get all this data entered (plus all the phone calls to NIPPO to confirm information). But yeah, have some fun and take a look at some of the entries. Right now it's just barebones stuff, no health data or anything like that.
Special thanks to Mr.Ishihara of the NIPPO Chiba branch for collecting this mountain of over 90,000 Shikoku entries, over all these years!
And protip (and another reason this data entry is costing me): NIPPO will send you copies of pedigrees on request, 200JPY/dog.
