This article explores the traditional Japanese beauty standard, the average height of Japanese girls today, and what Charles R. Tokoyama, CEO of Japan Insiders, considers to be the ideal height for a girl in Japan. Factors that contribute to this ideal height include age, body type/proportions, region within Japan, genetics and diet. The ideal range is between 5'1" - 5'4" (155cm - 163cm) depending on her body type/proportions rather than her age or region within Japan.
