Six breeds—the Akita, Hokkaido, Kai, Kishu, Shikoku, and Shiba—are Nippo’s natural-monument breeds; this wider list also includes dogs developed in Japan, a breed linked to Japanese court culture, and an indigenous Okinawan dog.
These 11 breeds have different histories and roles, so their shared association with Japan does not mean they have the same origin or temperament. Breed history and standards can help you understand a dog, but they cannot predict an individual dog’s health or behavior.

The six Nippo natural-monument breeds
Nippo identifies six breeds: Akita, Hokkaido, Kai, Kishu, Shikoku, and Shiba. Its historic standard groups them by size: Shiba is small; Hokkaido, Kai, Kishu, and Shikoku are medium; Akita is large. This official group is only part of the broader list of Japanese-associated breeds below.
1. Akita
The Akita is the large member of Nippo’s six. The Japan Kennel Club (JKC) traces it to Akita-matagi dogs used to hunt bears. After 1868, crosses with Tosa and Mastiff-type dogs increased the breed’s size and weakened some of its spitz-type features; later preservation efforts shaped the modern large Akita.

JKC’s Japanese Akita standard gives ideal shoulder heights of 67 cm for males and 61 cm for females, with a 3 cm tolerance for each. Akita classification varies between registries: the Fédération Cynologique Internationale recognizes the American Akita and Japanese Akitainu as separate breeds. The name “Akita” alone may not tell you which registry type a breeder means.
2. Hokkaido Inu
Hokkaido Inu is a medium Nippo breed from northern Japan, historically associated with Ainu hunting culture. JKC says its ancestors came with people moving from Honshu to Hokkaido in the Kamakura period, and describes the dogs as used to hunt bear and other game in severe cold and snow.
JKC gives a height range of 48.5–51.5 cm for males and 45.5–48.5 cm for females. This history describes the breed’s background; it does not guarantee how an individual Hokkaido will behave.
3. Japanese Chin
The Japanese Chin is a companion breed closely linked to Japanese court culture, but its deeper origin is described as Chinese in the American Kennel Club’s account. That account says ancestors were gifts from Chinese emperors to Japanese nobility, where the dogs became prized companions.
The Chin is a notable exception among the breed names discussed here: the Japanese name does not use inu, meaning dog. Its cultural history is a reason to include it in a broad list of Japanese-associated breeds, not to call it one of Nippo’s six natural-monument breeds.
4. Japanese Spitz
The Japanese Spitz was developed in Japan and is not one of Nippo’s six natural-monument breeds. JKC traces its development to large white German Spitz dogs brought to Japan around 1920 via Siberia and northeastern China. The breed appeared at a Tokyo exhibition around 1921, and JKC established a unified standard in 1948.
Its distinctive features include an abundant pure-white coat, pointed muzzle, triangular erect ears, and a plumed tail carried over the back. JKC’s standard gives males a height of 30–38 cm; females are slightly smaller.
5. Japanese Terrier
The Japanese Terrier is a small breed developed in Japan, not one of Nippo’s six. JKC says Smooth Fox Terriers arrived in Nagasaki from the Netherlands in the 1700s and were crossed with small local dogs; planned breeding fixed the breed in the early Showa period.

The standard describes a tri-colored head and a predominantly white body with black or tan markings; JKC lists an approximate height of 30–33 cm for both sexes.
6. Kai Ken
Kai Ken is a medium Nippo breed from the Kai region, now Yamanashi Prefecture. JKC says it was used chiefly for hunting boar and deer. Its brindle coat is a visible differentiator: the standard lists brindle, black brindle, and red brindle, and notes that brindling can become apparent as a puppy matures.
Ideal height is 50 cm for males and 45 cm for females, with a 3 cm tolerance for each, according to JKC’s standard.
7. Kishu Ken
Kishu Ken is a medium Nippo breed associated with the mountainous Kishu region, now linked with Wakayama and Mie. JKC says it was used mainly to hunt boar and sometimes deer. Its permitted colors are white, red, and sesame, though white became especially common after 1945.
Rank #3
JKC’s standard gives a height of 52 cm for males and 49 cm for females, with a 3 cm tolerance for each. JKC also notes that the breed’s colors were standardized in 1934.
8. Ryukyu Inu
Ryukyu Inu is an indigenous Okinawan/Ryukyu dog associated with Okinawa’s Yanbaru region and Ishigaki Island. A peer-reviewed review describes it as following a separate development path from the six main Japanese breeds.
Its recognition and preservation descriptions vary, so it should not be presented as one of Nippo’s six natural-monument breeds or assigned an unsupported registry status.
9. Shiba Inu
Shiba Inu is the small member of Nippo’s six and one of the most familiar Japanese dogs internationally. JKC describes it as a native Japanese dog used in mountain regions facing the Sea of Japan to hunt small animals and birds. The breed declined through crossbreeding; Nippo adopted its standard in 1934, and it received natural-monument designation in 1936.

JKC lists red, black-and-tan, sesame, black sesame, and red sesame. All accepted colors require urajiro markings. Standard height is 39.5 cm for males and 36.5 cm for females, with a 1.5 cm tolerance for each.
10. Shikoku
Shikoku, also known as Kochi-ken, is a medium Nippo breed from the mountains of Kochi on Shikoku. JKC describes it as a boar-hunting dog. The region’s relative isolation helped preserve the Honkawa line, and the breed received natural-monument designation in 1937.
Rank #4
Sesame is especially characteristic; JKC also lists red and black-and-tan. Its standard height is 52 cm for males and 49 cm for females, with a 3 cm tolerance for each.
11. Tosa Inu
Tosa Inu is a large mastiff-type breed developed in Japan. JKC says it was created by crossing Shikoku dogs with Western breeds including Bulldog, Mastiff, German Pointer, and Great Dane. Its history includes use in dog fighting; JKC describes its current use as a guard dog.
JKC describes a powerful dog with a short coat, dropped ears, square muzzle, and thick-based hanging tail. Minimum height is 60 cm for males and 55 cm for females. Breed history should not be romanticized, and local rules may vary; check current requirements where you live before considering any dog.
How this list is classified
The six Nippo natural-monument breeds are Akita, Hokkaido, Kai, Kishu, Shiba, and Shikoku. The Japanese Spitz, Japanese Terrier, and Tosa were developed in Japan from imported or mixed ancestry. The Japanese Chin is associated with Japanese court culture but has a Chinese origin story, while the Ryukyu Inu is an indigenous Okinawan/Ryukyu dog with a separate regional history.
These 11 are a defined popular list, not an exhaustive account of every historical or regional dog population associated with Japan. “Japanese dog breeds” is a useful umbrella term, but it should not blur differences in origin, recognition, or status.

FAQ
What are the six native Japanese dog breeds?
Nippo identifies Akita, Hokkaido, Kai, Kishu, Shikoku, and Shiba as its six natural-monument breeds. Their size groups are not all the same: Shiba is small, Akita is large, and the other four are medium.
Are all 11 breeds in this list native Japanese dogs?
No. The list combines the six Nippo breeds with Japanese-developed breeds, the Japanese court-associated Chin, and the indigenous Okinawan/Ryukyu dog. These categories have different histories and official statuses.
Is the Japanese Chin originally from Japan?
The American Kennel Club’s account describes the Chin’s deeper origin as Chinese and says ancestors were gifts to Japanese nobility. The breed is strongly associated with Japanese court culture, but that is different from calling it one of Nippo’s six native breeds.
Is Ryukyu Inu one of Nippo’s six natural-monument breeds?
No. The supplied research identifies the Ryukyu Inu as an indigenous Okinawan/Ryukyu dog with a separate development path; it is not among Nippo’s official six.
Recommended Free Tools
Are Japanese Akita and American Akita the same breed?
Registry classification differs. The Fédération Cynologique Internationale recognizes American Akita and Japanese Akitainu separately, so ask which registry and breed type a breeder or rescue means.
