|摘要: || 自古以來，八咫鏡、草薙劍、八坂瓊勾玉之三種神器被視為日本王權的象徵。在日本文學中，關於三種神器的描述也不少。其實，關於鏡、劍、玉的記載在中國文學中早已出現，鏡、劍、玉各自背後皆有其涵義。另根據儒教與道教經典，可瞭解中國王權思想與「天」的思想有所關連，而天的思想也對中國的王權造成莫大影響。因此在論及日本王權思想之時，必須追溯至中國古代天的思想。|
The Imperial Regalia of Japan consists of the sword Kusanagi no Tsurugi, the mirror Yata no Kagami, and the jewel Yasakani no Magatama. From ancient times, they have been regarded as the symbol of power, which belongs to Emperors of Japan. There are quite a few descriptions about the Imperial Regalia of Japan in Japanese literature as well. Actually, the thought of mirror, sword and jewel has already been described in Chinese literature, and each of them has their own meanings. In addition, according to the books of Confucianism and Daoism, the ideology of the emperor of China is relative to the thought of “sky,” and the thought of sky also greatly influenced the power of Chinese emperors. Therefore, it is necessary to trace back to the thought of sky in ancient China while mentioning the ideology of the Emperor of Japan.
How should the power of the Emperor of Japan be explained by means of Shinto? As everyone knows, emperors of Japan rule the country as descendants of Amaterasu due to the ideology of the emperors’ unbroken line. Actually, the proof of it is called “Tenjo Mukyu no Shinchoku”, which has already shown in “Kojiki” and “Nihon Shoki.” It means the oracle, which is as eternal as heaven and earth, and the Imperial Regalia of Japan just became the symbol of the oracle.
In this thesis, literatures of ancient Japan and medieval Japan will be used to describe the origins and meanings of the Imperial Regalia of Japan. Next, I will manage to explore the connection between the Imperial Regalia of Japan, ideology of Japanese emperor and Chinese ideology from a comparative point of view, and expound the ideology of the emperor of Japan symbolized by Imperial Regalia of Japan. By means of the above research method, the ideology of Japan and China is expected to be clarified in order to know more about the innate ideology of Japan — Shinto.
