Max Weber's social theory is so wide-ranging, so powerful, and so well constructed, that sociology since his time is often said to be nothing but footnotes to Max Weber. As we know, Weber's theory was constructed on the basis of his intimate knowledge of Europe, the Near East, India, and China, but not that of Japan, which hardly figures in any of his writings. Thus consideration of the Japanese case potentially throws a new light on Weber's social theory, and can suggest its revision.
