Japan has given the world several unique dog breeds, but the most recognizable are the Akita Inu and Shiba Inu. At first glance, they are almost twins: proud posture, standing ears, fluffy bent tail and sly expression of the face. Often people confuse these breeds, thinking that the Shiba is a small Akita. In reality, they are two completely different personalities, two histories, and two lifestyles. Let’s take a look at five key differences that will help you figure out who’s who.
1. Size and weight
This is the most obvious criterion. The Akita Inu is a giant among Japanese dogs. Its height can reach 70 cm at the withers and its weight exceeds 40 kg. This is a dog that impresses with its strength and massiveness. Shiba-inu, on the contrary, looks like a pocket version: its height ranges from 33 to 43 cm, and its weight usually does not exceed 12 kg. On a walk, they are easy to distinguish, even to a person who knows little about breeds. If you are looking for a compact friend for an apartment, the Shiba is the best choice, while the Akita requires space and a lot of exercise.
2. historical purpose
The Akita Inu has a noble past. These dogs once accompanied samurai and were used to guard and hunt big game – boars or even bears. Its character was formed as that of a reliable defender and a serious warrior.
Shiba-inu, on the contrary, was the assistant of simple hunters in mountainous areas. It was characterized by its agility and ability to move in difficult terrain. Her main task was to drive hares, birds or other small animals out of the bushes. That is why Shiba is energetic, attentive and has quick reactions.

3. character and temperament
The Akita Inu is a calm and poised giant. It is reserved with strangers, but extremely loyal to its family. Often Akita owners note that their pets have their own code of honor – do not fuss without reason, but are always ready to stand up for the owner.
Shiba Inu is quite different. It is an explosion of energy with the character of a true individualist. She is inquisitive, active, loves to explore everything around her and sometimes behaves as if she decides what to do. Shiba owners know well: training this breed requires patience, because it is stubborn and does not always willingly follow commands.
4. coat and color
Both breeds have a thick double coat that protects them from the cold. However, the Akita’s coat is much bulkier and requires more grooming, especially during shedding.
In terms of color: the Akita is common red, white, tiger or sesamo. The Shiba also has an interesting palette – from red to black with undercoat, as well as cream and sesamo. A characteristic feature of the Shiba is the so-called “urojiro”: light-colored areas of fur on the muzzle, chest and inner side of the paws, which give expressiveness to its appearance.

5. Life expectancy and health
Due to the difference in size, the life expectancy of these breeds is also different. The Shiba Inu lives an average of 13-16 years and is considered a long-lived dog. The Akita Inu has a slightly shorter lifespan of about 10-13 years. Large breeds are prone to joint and musculoskeletal problems, so Akita care requires special attention. At the same time, the Shiba, although it lives longer, has its own vulnerabilities: it can suffer from eye diseases or allergies.
Conclusion
Akita Inu and Shiba Inu are not “one dog in two sizes” but two different dogs. The Akita is majestic, calm, loyal and serious. The Shiba is perky, savvy, independent and stubborn. Both breeds are beautiful and charismatic, but you should choose them with your own lifestyle in mind. If you need a guard and a reliable friend in the country house – it is Akita. If you are looking for an active friend for walks in the city – this is the Shiba.
