True bantams of great antiquity, these are without counterparts in the large breeds. They are the shortest legged of all varieties and are standardized in three feather forms: plain or normal feather, frizzle feather and silkie feather. The frizzle feathered shall follow both the type and colours of the plain-feathered standards, but the ends of all feathers are to curl back and point towards the head. Feathers must be broad and as closely curled as possible. The silkie feathered refers to the feather construction. All birds must follow closely the general Standard, but body feathers shall have a silky, loose feather structure (i.e. feathers have no main centre vein). This cannot apply to primary and secondary wing feathers or to true tail feathers, which would nullify any true Japanese type.
