Pedigrees and health results


Now 9649 dogs


Welcome to the Database

The Nihon Ken (the Japanese Dog) are the 6 aboriginal Japanese breeds designated in Japan as 天然記念物 or Natural Monuments. This includes the Akita, Kishu, Shikoku, Kai, Hokkaido, and Shiba. As the populations for many of these breeds decrease every year it is becoming increasingly critical to collect as much data as possible about the remaining breeding stock. This data will hopefully help the guardians of the breed to make the best possible plans for breeding and preservation.

The most important part of this database is the health test results collected from breeders, clubs and databases from various countries, and the database's ability to calculate inbreeding coefficients (COI) and AVK. It is also possible to see the COI/AVK of a planned litters, to check health-results of listed dogs or just to browse through multi-generational pedigrees.

This database is set up to register dogs from all 6 breeds. In the top left corner of the website is a dropdown tab titled 'allBreeds'. The default setting of the site will allow you to browse dogs from all 6 breeds at the same time. If you wish to be more specific, toggle the 'allBreeds' dropdown menu and pick the breed of your choice. You will now only see dogs of this breed listed in browse and search.


There is still limited data available regarding genetic health issues in the Japanese breeds. As with all dogs, the Nihon Ken have been diagnosed with hereditary and non-hereditary health issues. As guardians of the breeds, their health is paramount, so tracking and removing the hereditary issues is an important focus. Some conditions that have been seen in the Nihon Ken are panosteitis, other joint related issues, hip dysplasia, possible IMPA, sebacious adenitis, VKH, split or abnormal heats, allergies, epilepsy, entropion, luxating patella, male infertility, pyometra, hypodontia, and cryptorchidism to name a few. Each breed seems to have it's own batch of health issues that affect it, so in the future we will sort out a list of what we are trying to track and focus on in each breed.

Entries to the database can be made by anyone with a breeder account. This is now an open database, so please be sure the data you are entering is correct. If you have any questions regarding this or other issues (such as incorrect data being entered to the site), feel free to contact us via the contact tab at the top of the site. Many of the pedigrees will be entered in Japanese, some in English, and some bilingual. The best way to search for individual dogs will be by using registration numbers. If you are looking for a user generated (and more user oriented) pedigree database for a simple google search should bring up databases for the Akita, Shiba, Hokkaido, and Shikoku.


If you would like specific pedigrees entered into the database, would like to make corrections to listed data, or need to get ahold of the administrator of the site, Shigeru Kato, can be reached at kato.the.walrus@gmail.com
