General appearance calls for a small to medium dog with a profuse pure white coat, pointed muzzle, triangular pricked ears, and plumed tail carried over the back.

The coat is a double coat consisting of a soft dense undercoat and a straight outer coat standing off from the body. The coat is short on the face, ears, and fronts of legs, but profuse on the rest of the body. Only pure white coloration is acceptable.

Other Organizations
The Japanese Kennel Club, as the breed's country of origin registry, maintains the foundational standard upon which other organizations base their descriptions. The Kennel Club of the United Kingdom recognizes the breed in the Utility Group with a standard closely aligned with the FCI specifications. The Canadian Kennel Club also recognizes the breed in the Non-Sporting Group. Australian and New Zealand kennel clubs follow similar guidelines emphasizing the pure white coloration, spitz-type characteristics, and balanced proportions. All major kennel organizations agree that the Spitz Japonais should present as a companion dog of elegant appearance with a profuse pure white coat, alert expression, and friendly but dignified temperament.
