He falls into the working class category. In 1931, the Kai Ken Aigokai registry was formed to preserve the dog. In fact in this year Dasuke Adachi discovered these dogs and in 1934 was actually designated a Natural Monument in Japan and also protected by law.
The Kai Ken was recognized in 1934 by the Japanese Kennel Club. It is not 100% certain but it is thought that the dog was brought to the United States in the 1950s.
An ancient breed, the Neapolitan Mastiffs are massive dogs with a history of protecting their family and their property. The breed has deep rooted protective instincts and they are very frightening in appearance. The Neapolitan is of the Molosser group of dogs, all of whom probably came from the same line. It is known that all the mastiffs in Europe are descendants of the Tibetan Mastiff. The Tibetan Mastiff is considered the most ancient of all canines.
The Asian Mastiffs came from India to Greece around 300 BC with Alexander the Great. Then the breed was brought to the Romans by the Greeks and then introduced them in their circus in fights. Another possibility is that around 500 BC the mastiffs came to Britain from the Phoenicians. Either way the Roman Molossus is the ancestor of the Neapolitan Mastiff.
The Romans crossed the breed with the English Mastiff around 55 BC and developed a premiere war dog that was called a Mastini.
The breed eventually became extinct in Europe with the exception of Campania. The breed was recognized in 1946 with the standard accepted in 1949. However, it is believed that the Neapolitan Mastiff has been continuously present in Campania for over two thousand years. The breed was initially developed as war dogs and for the Roman coliseum spectacles.
In 1946 Dr. Piero Scanziani established a program to breed them in Italy. He wrote the breed standard in 1949.
Today the Neo is a farm dog, an army dog, a police dog and a guard dog. They were shown in Italy for the first time in 1946 but only in 2004 was the breed recognized by the American Kennel Club (AKC). It was 1973 when the Neapolitan Mastiff Club of America was born and 1996 when the standard was approved by the AKC. They are still a rare breed in the United States.

With a lifespan of 14 to 16 years, and given the genetic purity of the Kai Ken, you aren't likely to battle with congenital health problems with your dog, but it is always good to be aware of certain minor health issues that he could succumb to.
He can suffer from a few common dog diseases such as progressive retinal atrophy or hip dysplasia.
This is a disease of the eye where there is wasting of certain parts, and in this case the cells of the retina develop abnormally. This can eventually lead to blindness. It’s an inherited disease that can occur in pure- and mixed breeds, and dogs with PRA shouldn’t be used for breeding.
It isn’t a painful condition, and the first symptom usually noticed in a dog is night blindness where you may notice him bumping into things at night and being reluctant to walk around in the dark.
The Neapolitan Mastiff is prone to many of the same issues as any massive, extra large breed. The most common of these is Cherry Eye.
Even though the coat is thick, the Kai Ken will require basic canine care, so a brush twice a week will be enough to keep the coat free of loose hair. He sheds more heavily a couple of times a year and then he will require more brushing.
He has always been used to hunt so he is a dog that will require regular exercise such as walks, hikes, swimming and ball games.
The nails of the dog should be trimmed regularly once they become long as long nails can be hazardous and can hook onto things, causing injury to the nail area.
The ears of the dog should be checked regularly for fleas and ticks, and teeth should also be brushed with canine toothbrush and toothpaste.
