The Japanese Bobtail’s tail is undoubtedly its most differentiating characteristic. Consisting of one or more ‘welded’ vertebrae, it can be folded on itself in any way, unique to each individual. The overall length of the tail is variable, but in general at its longest extension, the tip should be no more than 3 inches away from its body. This results in a pompom with long hairs spouting out in all directions (even on the short-haired variety). Poetically, they have been compared to chrysanthemum flowers that grow in Japan.

Japanese Bobtails’ bodies are muscular but slender and delicate as they have a semi-foreign medium body type. They are well-proportioned, and even their truncated tails fit beautifully with the rest of their bodies. Their hind legs are slightly longer than their front ones, but are slightly bent (as if ready to pounce), meaning that their back is straight. Their head is an almost perfect equilateral triangle, with soft, curving lines and prominent cheekbones. Their ears, are large, and are placed at right angles to their heads. Their eyes form a pronounced angle when seen in profile, and are large and oval shaped.
The Japanese Bobtail has virtually no undercoat. Their soft, silky hair is attached to their bodies and makes them look like porcelain statues. Both long haired (Longhair Japanese Bobtail) and shorthaired (Shorthair Japanese Bobtail) varieties exist. The longhaired variety can have beautiful collars that complement their chrysanthemum-esque tails.

They are very human oriented, and therefore it’s not surprising that they’re extremely affectionate! But they won't rest in your lap for very long. They prefer to wander and roam!

They’re an extremely playful breed who can have as much fun playing on their own with their toys as playing a game of fetch with their owner! If you don’t play with your Japanese Bobtail, they’ll easily find games to play in the house on their own...although these ‘games’ aren’t always appropriate!

They would much rather join in the fun, or better yet, create it!

Their curious and energetic nature makes them resourceful and intelligent cats. They pick things up and take in information very quickly.

They usually adapt well to strangers, but this character trait does depend on the individual cat.

Despite being very attached to their owner, they do like to go about their own business ... and they can definitely keep themselves occupied.

They are known as very chatty cats. They are often actually considered good ‘singers’, as their "vocabulary" and vocal register are rather beautiful, making their noises a pleasure to listen to.

They need activity and play. Their short tails do not hinder their jumping ability or their ability to balance.

They don’t have a high tendency to runaway, but their curiosity can get the better of them, causing them to go outside and explore. Their curiosity can be increased by a lack of exercise and stimulation.

They are not fussy eaters, so you’ll have to keep an eye on them to prevent overeating!

They are only really known for getting on with other members of their own breed, but with adequate introductions, they can also get on with other breeds of cat.

They get on very well with dogs as long as they’re given enough time to adapt!

They have a reputation for loving children. Perhaps this is due to their playful nature? Nevertheless, you’ll still need to monitor their interactions though, to reduce the risk of incidents between animals and children.

Since they’re very active and require a lot of interaction, their owner must be prepared to deal with these characteristics. These are not sofa cats, and if you fail to meet their activity needs they’ll get up to all kinds of feline mischief!

Shedding is minimal on these cats.

They live 16 years on average.

Their lack of undercoat can make them sensitive to cold temperatures. However, their coat is reasonably waterproof and they adapt well to warmer climates.

The Japanese Bobtail has a slight tendency for obesity. Therefore you need to pay attention to their diet and exercise.

They don’t suffer from any particular genetic diseases. Obviously, they can develop all the same physical and oral diseases as all domestic cats, but they are generally a healthy breed. The dominant gene responsible for its unique tail is different to the Manx gene and thus is not associated with spinal abnormalities.

There is nothing in particular to report concerning their reproduction. They are only authorized to breed with other Japanese Bobtails, but Shorthair and Longhair individuals can mate together, as they are fundamentally the same breed.

There are many legends regarding cats in Japan, but it seems that the first cats came from mainland Asia, possibly from China or Korea. No one knows exactly when the genetic mutation responsible for the chrysanthemum tail occurred, but since it is present throughout Asia, it potentially existed prior to its arrival in Japan. The mutation is a dominant gene: thus when it is transmitted to the kitten, it forms automatically. The pompom tail spread very quickly in Japanese cats, as the country is a set of islands, and are therefore quite isolated.
The first Japanese Bobtails were given to the Emperor of Japan over 1000 years ago. He loved them so much that he considered them aristocrats and members of the court and the little cats were treated as such. However, in the 1600s, the sale and purchase of cats became illegal and the authorities demanded that all cats were released into the wild to be free. Why did they do this? Silk production was threatened by vermin that ate the worms and their cocoons. As natural hunters of this vermin, the cats were a desperate measure to protect the silk industry in Japan. However, as a result of this, Bobtails became alley cats in Japan.  
They are an entirely natural breed and are in fact one of the oldest still in existence. In 1968, the first specimens were imported to the United States where breeders Judy Crawford and Elizabeth Freret worked on getting them recognised by the various feline associations.
