Dog fighting has been a part of Japan’s history since the 14th century. The Shikoku Inu breed was unbeatable in Japanese dogfighting arenas before Westerners arrived. However, after Commodore Perry arrived in Japan in 1854, Japanese dogfighters began to crossbreed their native stock with foreign canines. This led to the creation of the Tosa breed, a hybrid of Shikoku Ken and Western species. Bulldogs, Mastiffs, German Pointers, and Great Danes were among the Western dogs used to improve the breed. Saint Bernards and Bull Terriers may have also been involved, but it is unclear when they were used. 

The Tosa breed is highly respected in Japan, where they are considered the equivalent of Sumo wrestlers and are a symbol of great honor and ceremony. In the United States, the Tosa Ken serves as a companion dog and guardian of the home.

The Tosa Inu is a big dog with a short coat. They have a robust and agile body and a dignified manner. Their bodies are slightly longer than they are tall. The head is big and broad, with a square-shaped muzzle, droopy lips, and a noticeable wrinkled flap of skin hanging from the neck. The ears are medium-sized, droopy, and set high. The tail is thick at the base, tapers off at the tip, and is not cut. In addition, these pups can be a single color, striped, black with markings, or a mix of colors. They should look like a powerful and flexible athlete—a true dog samurai.


The Tosa Inu is usually a chill and obedient dog with a calm but watchful nature. They’re a bit reserved with strangers but affectionate with their own family. They are also naturally wary of other dogs and may react aggressively if they think other dogs are intruders. Keep in mind that positive-enforced training works best with this breed because they want to make their owners happy. It takes a while for Tosas to mature, and some pups might not reach their prime until they’re four years old.


The Tosa Inu breed has a short, dense coat that doesn’t require much grooming. Brushing them once in a while is enough. Also, if you give them a bath once in a while, they’ll look great. Don’t forget to keep their nails trimmed regularly with a nail clipper or grinder to avoid any problems. Check their ears regularly to prevent any buildup of wax and debris that can cause infection. Lastly, brush their teeth to keep their dental health healthy.


Tosas are known for their calm disposition, but like all dogs, they require regular exercise to maintain good health and mental well-being. Outdoor activities such as running in a fenced backyard, going for walks, hiking, and retrieving balls can help them expend energy and stay fit. On the other hand, indoor activities like playing fetch with a ball or learning new tricks can also provide mental stimulation and physical exercise. Additionally, participating in dog sports such as agility, obedience, or rally will offer a fun and effective way to keep your Tosa Inu intelligent, active, and healthy.

Tosas are smart and love to make their owners happy, but they can also be quite stubborn sometimes. It”s best to use training methods that are firm but still fair, like positive-reinforcement training, and make sure to always stick to the rules.

You also need to socialize Tosa Inu puppies early and often to avoid them becoming too defensive. If you notice that your pup is showing signs of aggression from an early age, get help from someone who knows about dog behavior. If these signs are ignored, it could lead to bigger problems later on, especially since Tosa Inu dogs can be quite large and strong.

Many readers have loved learning how to train their dogs based on scientific methods from a free workshop conducted by Dr. Alexa Diaz (one of the top service dog trainers in the U.S.) and Eric Presnall (host of the hit Animal Planet TV show “Who Let the Dogs Out”) at the K9 Training Institute. In the free online dog training workshop, you’ll discover:

    1. How to train your dog using body language rather than verbal cues
    2. The 3 key techniques that service dog trainers use to train dogs and how you can use them too
    3. The most important step that “normal” dog owners have been missing (this is very important to get your dog’s attention, and it works 100% of the time)
    4. How to stop bad behaviors like excessive barking, pulling on the leash, jumping, etc.
    5. Why a lot of dog owners are unable to establish the amazing bond that service dog trainers have with their dogs


Whether your dog is a puppy or an adult, this pre-recorded workshop will help you train them successfully. You may not want to miss the chance to learn these groundbreaking techniques. Here’s the free workshop.


Most Tosas are healthy dogs, but some may face health issues during their lifetime. If you’re planning to adopt a Tosa Inu, you should work with a responsible breeder who can tell you about specific health concerns that affect the breed. A good breeder would have tested the adult Tosas before breeding them, so you can be sure your pup won’t inherit any health conditions you don’t want.


Tosas are mastiff dogs weighing between 100 and 200 pounds. They might eat a lot, but you should keep an eye on their portions, especially when they’re puppies. They need to grow slowly to avoid joint issues like hip and elbow dysplasia. Feeding them smaller portions of high-quality food several times throughout the day might be the way to go. That can help prevent bloat, which is super important. Also, try not to feed them right before or after they exercise.

If you’re considering bringing a Tosa Inu into your home, you should know that they love to exercise and need a large fenced yard to run around. They can handle different types of weather, but they need plenty of fresh water in the summer to stay cool and hydrated.
