The Japanese Akitainu is the largest of the native dog breeds of Japan — a large, sturdily built, well-balanced Spitz-type dog whose head, triple coat, and curled tail are defining physical features of this unique breed. It is an alert, independent, dignified, and self-confident breed, loyal and protective of its family.
The Akita is the only Nihon Ken included in the "large" class, designated as a national natural monument in 1931, and is well-known not only in Japan but also overseas, where it became the first Nihon Ken to be readily recognized.
A Hunter's Dog of the Snowy North
The Matagi of northern Japan are hunters who have existed for hundreds of years, utilizing their hounds — the Matagiinu — to track and bay bear, boar, and deer. The Matagiinu was a medium-sized hunting dog with stand-up ears and a curled tail, and is considered the ancestor of the modern Akita breeds. The Akita Inu traces its roots to the Matagi Inu, a medium-sized dog historically used by the traditional hunters of the Tōhoku region for tracking and subduing large game such as the Japanese black bear, wild boar, and Japanese serow in snow-covered mountain terrain.
Towards the end of the Edo Era, civil unrest in the Dewa region resulted in peasant uprisings. Consequently, the nobility and those in the upper socioeconomic strata began using the local dogs to guard their property, breeding the medium-size Matagiinu toward a larger, more imposing size. During the Meiji and Taishō periods, to increase size for guarding and dogfighting, the Matagiinu was mixed with the Tosa Fighting Dog and other foreign breeds, creating the Shin Akitainu ("new Akita dog").
By the early 1900s, Japanese academics and breeders felt the Shin Akitainu had lost its native Japanese dog characteristics. Influenced by a wave of nationalism and a growing desire to preserve native dogs, breeders were encouraged to breed back to the Nihonken morphology. In 1927, the Akitainu Hozonkai (AKIHO), the Akita Dog Preservation Society, was established in Ōdate, Akita Prefecture. In July 1931, the Akita Inu became the first domestic dog breed designated as a national natural monument. In 1934, the first Japanese breed standard for the Akita Inu was listed.
The breed experienced a huge decline during World War II, when it was used for its meat and fur, with efforts made to preserve the breed by crossing the remaining lines with German Shepherds to prevent extinction. After the war, Morie Sawataishi and others began breeding the Akita for a standardized appearance — a major reason the breed exists today. It was not until the 1960s-1970s that the foxier Japanese type started to diverge from the American type, and the two became completely separate breeds with their own standards. The Japanese Akitainu was recognized by the AKC in 2023.
Large, Sturdy, and Well Balanced
The Japanese Akitainu is a large, sturdily built, well-balanced Spitz-type dog. Males stand 25 to 27½ inches at the withers and weigh approximately 65 to 75 pounds; females 22½ to 25 inches and 55 to 65 pounds. Males have a height-to-length ratio of 10 to 11; females have a slightly longer body length.
The breed's defining physical features are its head, triple coat, and curled tail. The head is large and bear-like, with erect, triangular ears set at a slight angle following the arch of the neck, and small, dark, deeply set, triangular eyes. The thick, waterproof triple coat comes in red, white, or brindle, all with urajiro — whitish fur on the ventral areas, the sides of the muzzle, cheeks, and inside of the legs. The tail is thick, well-let-down, and carried in a single or double curl over the back. The gait conveys stamina through brisk, powerful movement.
Alert, Independent, and Dignified
The Japanese Akitainu possesses composure, a strong courageous character, loyalty, obedience, dignity, keen senses, and agility. Its outward appearance reflects an inner spirit of calm, quiet strength, and courage. The breed is loyal and protective of its family members, but can be reserved and aloof around non-family members, especially strangers, and some may be intolerant of other dogs, particularly dogs of the same sex.
A survey on canine behavior in five "ancient" breeds found the Akita to be the most aggressive toward other dogs, with most human-directed aggression involving a visitor on the Akita's territory — highlighting the defensive nature of the breed. Because of their strong will and intelligence, they are not recommended for first-time dog owners.
Exercise and Activity
The Japanese Akitainu has moderate energy and is a sturdy dog capable of long hikes and trekking, as well as being a watchdog. Today the breed is used primarily as a companion dog, but also competes in conformation showing, obedience trials, tracking trials, and agility competition.
| Dog | Daily exercise | Notes |
|---|---|---|
| Puppy | 3–4 short play sessions of 10–15 minutes | Keep walks gentle; avoid hard surfaces while growing |
| Adult | 30–45 minutes total walk or play | Split into two shorter sessions if preferred |
| Senior | 20–30 minutes of gentle walking | Slow the pace and shorten distance with age |

Training a Japanese Akitainu
The Japanese Akitainu is very strong-willed and intelligent, and once a bond is formed, they can be very responsive to training. Early and thorough socialization is essential — dog-on-dog aggression has been noted in the breed, so socialization at a very early age and throughout life is essential. They are known to be wary of strangers and unknown dogs.
The Dog Training Guide and Puppy Care Guide offer a solid foundation.
Grooming a Japanese Akitainu
The Japanese Akitainu has a thick, waterproof triple coat that sheds heavily twice a year when it "blows" its undercoat — during these times, daily brushing is essential. The rest of the year, weekly brushing is sufficient. Routine care includes nail trimming, ear cleaning, and tooth brushing.
| Task | Frequency | Notes |
|---|---|---|
| Brushing | 1–2 times a week | Brush in the direction of the coat and check for tangles |
| Bathing | Every 6–8 weeks or as needed | Use a mild dog shampoo |
| Nail trimming | Every 3–4 weeks | Trim when you hear nails clicking on the floor |
| Ear checks | Weekly | Look for wax, redness, or odor |
| Teeth brushing | 2–3 times a week | Dental chews help as a supplement |

Feeding a Japanese Akitainu
A Japanese Akitainu should be fed high-quality food appropriate to its age, size, and activity level, typically in two meals per day. As a deep-chested large breed, avoid vigorous exercise immediately after meals to help prevent bloat, which can be life-threatening.
| Life stage | Meals per day | Portion per meal (approx.) | Notes |
|---|---|---|---|
| Puppy (under 6 months) | 3–4 meals | 1–1.5 cups | Use a large-breed puppy formula |
| Adult | 2 meals | 2–3 cups | Adjust to activity level and body condition |
| Senior (7+ years) | 2 meals | 1.5–2.5 cups | Consider a senior or joint-support formula |
Your veterinarian can recommend the right diet and portions.
Health and Veterinary Care
The Japanese Akitainu is generally hardy, with a UK study finding a life expectancy of 11.4 years — dogs can live for over 10 years. Due to their size they can suffer from hip and elbow dysplasia. They are also known to suffer from amelogenesis imperfecta (a health issue affecting tooth enamel), entropion, progressive retinal atrophy, gastric dilation volvulus (bloat, which can be life-threatening), a blood-clotting disorder called Von Willebrand Disease, and a range of immune system problems.
| Check-up | Frequency | Notes |
|---|---|---|
| Wellness exam | Annual | Includes dental and weight check |
| Vaccinations | Annual booster | Follow your veterinarian's schedule |
| Heartworm prevention | Monthly (or as advised) | Year-round in most regions |
| Dental check | Annual cleaning as recommended | Watch for tartar buildup |
| Hip and elbow dysplasia screening | Discuss with your vet | OFA/PennHIP on parents |
| Senior wellness checks | Start from age 6–7 | Early detection of age-related conditions |
