Philtrum (jōdan)
Upper-lip midline target
The philtrum is recorded here as the jōdan (high-level) face target retained in the kata attack vocabulary. Its point is shown on the upper-lip midline because the manuals name the face line rather than provide normalized diagram coordinates. This is a historical target label for the kata tradition, not a strike instruction.

Kodokan Judo Institute, Kime-no-kata (primary_canonical)
The Kime-no-kata technical specification, in its jōdan face-attack sequence, documents the high-level face/upper-lip line represented here; the normalized coordinate is editorial.
Jigoro Kano, Kodokan Judo (primary_canonical)
Kano’s Kodokan Judo, in its discussions of kata and self-defence, documents atemi as an auxiliary striking element within judo’s broader throwing and control curriculum; it does not supply the normalized body coordinate used here.
