In the Meiji era, girls' school regulations explicitly stated "standing urination prohibited," indicating that a significant number of women engaged in this practice. One method of female urination involves bending forward, sticking out the buttocks, and squatting slightly to direct the stream backward. During the Tokyo Olympics, special urinals for this purpose were installed in stadiums for female athletes. Another method of standing urination without aids involves using fingers to spread the labia majora and labia minora to control the flow. More women than one might expect relieve themselves without squatting. Standing urination was perfectly common until the Edo period, and even today, many women continue the practice without concern for being seen. Witness the acts of 55 women urinating standing up, recorded both indoors and outdoors.
