Japanese Akitainu.

FCI 255 utilization: companion dog. FCI history: the Akita Matagis, medium-sized bear-hunting dogs, were used as fighting dogs from 1603 in the Akita region and from 1868 were crossed with Tosas and Mastiffs, which increased size but lost Spitz type; dog fighting was prohibited in 1908 but the breed was kept and improved as a large Japanese breed. UKC: a member of the Spitz family, originally used for bear hunting, crossed with the Tosa-inu and European Mastiffs to increase size and value as a fighting dog; today a dignified, quick and agile breed, loyal and highly protective of its family. Japan Kennel Club (translated): in the old Akita region there were Akita Matagi dogs (bear-hunting dogs); the dog is now classed as a companion (family) dog. Wikipedia (English): the breed traces to the Matagi Inu, a medium-sized dog used by the Matagi hunters of the Tohoku region; it was also used in the Russo-Japanese War to track prisoners of war and lost sailors..

AKC and Wikipedia ranges overlap; both stand and the span covers both.

Coat

UKC: triple coated; the outer coat is a coarse, straight guard coat, the second is a thicker, somewhat soft undercoat, and the third, closest to the skin, is generally thicker and wool-like; red, brindle and white are acceptable and all but white need urajiro; long coat is an eliminating fault, pinto markings and black mask are disqualifications. FCI: outer coat harsh and straight, undercoat soft and dense, slightly longer hair on the withers and rump and on the tail; red fawn, sesame, brindle and white, all but white with urajiro; long hair (shaggy) and black mask are disqualifying. Wikipedia (English): a short double coat similar to other northern spitz breeds.

The work

What it was built to do in the field, and what a test or trial asks of it.

Role

FCI 255 utilization: companion dog. FCI history: the Akita Matagis, medium-sized bear-hunting dogs, were used as fighting dogs from 1603 in the Akita region and from 1868 were crossed with Tosas and Mastiffs, which increased size but lost Spitz type; dog fighting was prohibited in 1908 but the breed was kept and improved as a large Japanese breed.

Editorial and national-club views are shown beside the standards, labelled; where they disagree both stand (Chad, Oct 8 2026).

Primary game

UKC: bear hunting (the breed's original use). FCI and Japan Kennel Club: the Akita Matagi, a medium-sized bear-hunting dog, is the foundation. Wikipedia (English): the Matagi Inu ancestors were used for tracking and subduing large game such as Japanese black bear, wild boar and Japanese serow in snow-covered mountain terrain.

Breed clubUnited Kennel Club

The game is that of the ancestral Matagi dog; no source read describes present-day hunting use of the Japanese Akitainu itself. Editorial and national-club views are shown beside the standards, labelled; where they disagree both stand (Chad, Oct 8 2026).

Field trial standard

FCI 255: without working trial.

How to read this page

Every value carries a label. Measured means peer-reviewed data on many dogs. Studied means peer-reviewed, smaller or indirect. Breed club means a club or registry states it. Editorial means expert opinion with no measurement behind it. Where two good sources disagree, both are shown and neither is averaged.

Published when the entry rests on the best information available from no fewer than three independent sources, checked by a second pass that did not write it. 5 sources on this page. Found something wrong? Tell us and the correction is logged with its date.
