I don't have numbers for all breeds from last year, but there were only 252 Kishu pups and 306 Shikoku pups registered in Japan.
For some clarity on just how bad the decline in numbers is, in 1971 there were 7061 Hokkaido puppies registered with the HKH. In 2018 there were 242.
The early 70's were the heyday of the medium size Japanese breeds with 90074 new dogs registered over the 4 breeds in 1973. In 2018 there were 1661.
