Epigastrium (chūdan)
Upper-abdominal / solar-plexus line
The epigastrium, often described in modern glosses as the solar-plexus line, is the central chūdan upper-abdominal target represented in this map. The coordinate is a normalized editorial projection onto the upper abdomen and should not be read as a meridian or esoteric point. Its inclusion follows the kata-integrated atemi classification rather than kyūsho-jutsu theory.
