By comparison, the Hata line is characterized by its heavier bone structure. The front body is more developed than the rear. This line possesses a wider skull, smaller ears, and a rich undercoat. There is also a difference in the shape and color of the eyes. The Hata Shikoku is mostly sesame and red. Black & tan is rare. Most influential dog: Goma-go [BOB at the Nippo National Show, 1937].

After the war, the Shikoku dog was bred and known by two bloodlines. The Choshun line (Honkawa line) and Matsukaze line (Hata line). The Choshun Shikoku were descendants of Choshun-go. The Matsukaze Shikoku was descendants of Matsukaze-go (descendent of Goma-go. BOB at the Nippo show, 1950). These two lines, Choshun and Matsukaze, were bred separately after the war until about 1955. It was following this time that the lines were mixed to improve the breed. Presently, there is no separation between the Honkawa line and Hata line, although characteristics of each can be seen represented in the breed.

The Shikoku, as it is known today, is a medium-sized dog ranging in weight between 30-50 lbs. The accepted coat color for the Shikoku is sesame, red sesame, and black sesame. The standard markings are called "urajiro" which can be interpreted as white or lighter color defining the ventral area of the dog [the sides of the muzzle, the cheeks, below the jaw and neck, on the chest and abdominal area, the underside of the tail, and on the inside of the legs] and areas defining the brow of the eye. Crème or white Shikoku ken and markings other than urajiro may occur and can be argued as not acceptable for show.

Although this breed resembles a large Shiba-Inu, there are differences between the two breeds. The Shikoku dog’s general temperament exhibits more of a calm nature with less willfulness or stubborness. They have a tolerant disposition and are naturally obedient and submissive to their owner. The Shikoku dog's primitive nature requires an experienced dog owner. This breed is reserved and aloof, especially around strangers. It is best to give this breed proper socialization from an early age. Shikoku dogs possess a high prey drive and are very quick to react to this instinct.

The Shikoku dog is extremely rare and only a small number are known to exist outside of Japan. Great efforts are being made to protect and preserve this breed. The Shikoku dog is truly a natural treasure.
