Tadasuke Takata was a prominent scholar in the study of Chinese characters in modern Japan. The concept of graphic variation reflected in his work Kochūhen holds significant theoretical value and research importance. This paper focuses on his writings to systematically examine Takata’s歸納 and interpretation of the evolutionary patterns of Chinese characters. From a diachronic perspective, his theory of graphic variation summarises five major patterns of character evolution from the standpoint of structural change: component addition, component omission, semantic adaptation, component substitution, and comprehensive transformation. At the same time, it reveals the mechanisms behind the development of Chinese characters from both internal and external dimensions, discussing the influence of human writing habits and other factors on graphical evolution. His approach was not only methodologically pioneering but also provided an important reference for subsequent research on character evolution. As a foundational study on the structural evolution of Chinese characters, it is a cornerstone of modern East Asian character theory. His systematic歸納 and research demonstrate considerable advancement and offer valuable insights for understanding the development of East Asian character studies. However, his work is also limited by inconsistent classification, lack of depth in analysis, frequent misinterpretations of character forms, and superficial theoretical explanations, which overall restrict its academic impact.
