Ishikawa Phenotype - Face Features & Origin
The Ishikawa phenotype is a east asia human phenotype documented in historical anthropology literature. This page presents the Ishikawa phenotype average face composite, its geographic distribution, physical characteristics, historical background, and academic references.
Average Face
The Ishikawa phenotype average face is a composite synthesized from multiple individual photographs by historical anthropologists. It represents a statistical impression of recurring facial features, not a real person.

Geographic Distribution
The Ishikawa phenotype is native to East Asia. The historical distribution below reflects approximate centers of prevalence documented roughly 1500 years ago; modern borders and population movements have since blurred these boundaries.
Approximate coordinates: 35.00°, 110.00° (latitude, longitude).
Physical Characteristics
Yellowish light brown skin with coarse straight to wavy hair. Short, mildly macroskelic, ectomorph to endomorph. Mesocephalic, orthocranic. Mesorrhine, sometimes mildly platyrrhine nose, often with a depressed root. Face moderately short, straight and shallow, jaw weak. Eyes are relatively large, the cheekbones are weakly prominent. The Mongolian fold appears sometimes.
Historical Background
Special Japanese type, influenced by ancient regional elements. Named after the Ishikawa region of Honshu. Probably represents admixed variant of the Ainuid Miyato Island dwarf type of the Neolithic. Most common in the northern middle and northeastern part of Honshu Island. Sometimes in Ainu. Occasionally found across all Japanese islands.
