Catalog portraits for Japanese are AI-generated adult subjects; the measurements on this page come from documented photographs of real people, not from these images.

Overall face shape

n = 43 assessable

Macro-level shape of the face derived from facial outline (forehead width, cheekbone width, jaw width, face length).

ValueSharen
RoundLength and width approximately equal; soft jaw and forehead curves.58%25
OvalLength approximately 1.5x width; balanced forehead and jaw with widest point at cheekbones.19%8
Oblong / longLength substantially greater than width; balanced forehead and jaw.12%5
SquareLength and width approximately equal; angular jaw and forehead.12%5

Vocabulary: Overall face shape (face_shape_qualitative)

Cheekbone (zygomatic) prominence

n = 43 assessable

ValueSharen
Full / youthfulAnterior midface fullness; smooth nasolabial fold; defined cheek apple.64%27
BalancedAverage midface fullness.33%14
Flattened / agedReduced midface fullness; deepened nasolabial fold; visible tear-trough; mid-cheek descent.2%1

Forehead shape (sagittal)

n = 41 assessable

Profile shape of the forehead in lateral view.

Vocabulary: Forehead shape (sagittal) (forehead_shape_qualitative)

Jaw width (bigonial)

n = 43 assessable

Width of the lower jaw at the gonial angles (bigonial breadth) relative to the cheekbones (bizygomatic breadth).

ValueSharen
Narrow (tapered)Bigonial breadth substantially less than bizygomatic; tapered lower face.26%11
BalancedBigonial breadth approximately 75-85% of bizygomatic; aesthetic reference range.9%4
WideBigonial breadth approaches or exceeds bizygomatic; squared or wider-than-cheekbones lower face. Common in East Asian populations.65%28

Vocabulary: Jaw width (bigonial) (bigonial_breadth_qualitative)

Mandibular angle (gonial angle)

n = 43 assessable

Sharpness of the gonial angle.

ValueSharen
Soft / obtuseSmooth, rounded transition with no distinct angle. More common in female physiognomy and with subcutaneous fat coverage.84%36
ModerateStandard 120-130° angle; defined but rounded gonial transition.14%6
Sharp / angularVisible 90°-leaning angle at the gonial point; defined jawline. More common in male physiognomy and in East Asian populations.2%1

Vocabulary: Mandibular angle (gonial angle) (gonial_angle_qualitative)

Chin shape (frontal)

n = 43 assessable

Shape of the chin in frontal view.

ValueSharen
RoundedSmooth U-shape; no distinct point or angle.84%36
PointedV-shaped chin with narrow apex.14%6
SquareWide, flat chin with sharp lateral angles.2%1

Vocabulary: Chin shape (frontal) (chin_shape_qualitative)

BalancedPogonion approximately at the Riedel reference plane.93%40

Vocabulary: Chin projection (sagittal) (riedel_pogonion_qualitative)

Where these numbers come from

43 publicly documented portraits of notable Japanese people were assessed by a vision model against the full 22-vocabulary schema, one value per dimension. Values are what the photographs show, read by a model, not population measurements. Each table counts only portraits where the value could be assessed; covered, obscured and unclear portraits are reported separately.

Notable-people corpora skew older, so hair color over-represents gray and white, and image quality varies. Treat shares as a description of this sample.

These rows are not yet in the published catalog dataset, which currently carries the earlier single-row analysis; see the methodology. A family page exists only when at least 10 portraits carry an assessable value.
