A will passed from one genius to another

In the middle of the Edo period, the study of the Japanese classics, kokugaku, reached a great turning point. One of its central figures was the scholar Kamo no Mabuchi (1697-1769). Mabuchi inherited the work of earlier founders of kokugaku such as Keichu and Kada no Azumamaro, built a system of learning of his own, contributed greatly to the growth of kokugaku, and strongly influenced the intellectual movements that followed.

The root of Mabuchi's scholarship was a thorough study of the Man'yoshu, the oldest anthology of Japanese poetry. It was not merely an interpretation of the words of the poems. It was a vast scholarly journey that aimed to find the spirit of the ancient Japanese expressed in the verse, their way of life, and the "way" they valued. Through it Mabuchi found in the Man'yoshu a style without ornament, masculine, open, and strong, which he called "masuraoburi." In contrast to the delicate and graceful "taoyameburi" of later ages and the Chinese "karakuniburi," he took it to be a beauty peculiar to Japan and the ideal spirit of the ancient Japanese made visible. He pursued this plain and pure ancient spirit all his life, and in the end he came to dream of deciphering a certain classic after the Man'yoshu.

It was the Kojiki. Completed in 712, it is the oldest book in Japan, but for its peculiar way of writing and its difficult vocabulary, its contents stayed closed to most people for a long time. Mabuchi believed that the Kojiki was the most important key to unlocking the pure spirit and thought of the ancient Japanese.

Sadly, despite a lifetime of searching, this great dream ended halfway. When the moment to take up the Kojiki came, he was already old, and he never completed a full commentary on it himself. It remained an "unfinished dream." Mabuchi, who held an extraordinary dream of reading the Kojiki, hoped a young person would appear to carry on his work, but no such person came, and the years only passed. Yet the future of kokugaku that Mabuchi opened would advance greatly through a fateful meeting with a young genius, and would later become the force that changed Japan itself.

That person was Motoori Norinaga (1730-1801). Born in Matsusaka in Ise Province (now Matsusaka, Mie Prefecture), Norinaga ran the family cotton business and had a strong passion for learning from his youth. During his medical studies in Kyoto he happened to read the writings of Keichu, the pioneer of kokugaku, and this became a great turning point: he went deep into the world of kokugaku by teaching himself. Norinaga spent his life as a town doctor in Matsusaka, and alongside that he immersed himself in a vast study of the classics and firmed his will to open the next road.

Through his study of the Genji Monogatari of the Heian period especially, Norinaga proposed "mono no aware," an aesthetic and emotional ideal peculiar to Japan. The thought of mono no aware became the intellectual foundation of his scholarship. It runs through the method he took up in his Kojiki study, of trying to understand the spirit of ancient Japan by setting aside the later values of Confucian morality and the Buddhist law of karmic retribution.

Mabuchi had already set himself against Buddhism, which held great influence in Japan before the Edo period, and Confucianism, which held great influence in the Edo period, and conceptualized these foreign values as "karagokoro," the Chinese mind. Karagokoro comprehensively names the thought and philosophy of China that deeply influenced Japan through history. The idea is that beyond removing its influence lies the true Japanese spirit. Mabuchi and Norinaga took karagokoro to be "a mold of thinking that rationalizes things and tries to judge right and wrong." For my part, I take setting this mold aside for a time to be the way to come near the words of antiquity. Mabuchi did not simply reject karagokoro; he made a point of studying in detail how it had influenced the Japanese spirit. It was Norinaga who, setting karagokoro aside for the time being, pushed straight on to the source of the Japanese spirit. At that time Confucianism held overwhelming influence, and the revolt against karagokoro was a spirit shared by only a few scholars of kokugaku.

As this will for the future began to form in Japan, the aged Mabuchi, who had laid the foundation of kokugaku, and the young Norinaga, who would become its most important figure, finally met, in 1763. It was the night of May 25, 1763. Kamo no Mabuchi (67), traveling in the Kansai area to visit Ise Shrine and for other purposes, was staying at an inn in Matsusaka. The young Motoori Norinaga (34) heard of it and suddenly came to call. Norinaga, who had long admired Mabuchi, learned that he was staying in his hometown and went to the inn on nerve alone, to show his own will for kokugaku. It was an important event. And in fact it was the only time the two ever met in their lives.

Mabuchi was deeply moved by the earnest words and feeling of this unknown young man who came without a letter of introduction. He welcomed him warmly and accepted him as a pupil. To pass on his own will, Mabuchi spent the whole night giving Norinaga precious teaching on how to proceed in his studies, and it changed Norinaga's life. Mabuchi explained then that to decipher the difficult Kojiki, one must first come to a deep understanding of ancient usage and expression through the Man'yoshu.

From this fateful meeting Norinaga became Mabuchi's formal pupil, and across the physical distance between Edo and Matsusaka a lively scholarly exchange began by letter. Mabuchi answered Norinaga's sharp questions on the Man'yoshu one by one with care. In time, respecting Norinaga's talent and firm will, he entrusted him with the dream of studying the Kojiki that he had himself been unable to fulfill, and supported the work wholeheartedly. So Norinaga took up Mabuchi's will and resolved to take on the great dream of deciphering the Kojiki. That he began serious work on the Kojiki the year after he entered Mabuchi's school shows the decisive influence of that meeting on his life.

Remarkably, Norinaga began serious study of the Kojiki around 1764 and spent 35 years on it. He gave his whole life to the work of deciphering it. In 1798 he completed the great work in 44 volumes, the Kojiki-den, and changed history.

That we Japanese can now read the Kojiki easily is Norinaga's achievement, and I cannot thank him enough. In his day the Kojiki, with its special use of kanji and many words that carried no meaning, was a text that even then could not be read, and scholars had in effect left it alone. By day Norinaga lived a busy life as a town doctor, seeing many patients to make his living; at night he shut himself alone in his study and wrestled with the Kojiki word by word, steadily carrying on a vast labor of annotation. The precision of that work, and his astonishing patience and concentration over decades, are truly worthy of wonder.

Norinaga's method did not rely lightly on the commentaries of each age that had gone before. It rested on thoroughgoing textual positivism. What he valued above all was returning to the "sense of the words" the ancient Japanese actually used, and facing the text of the Kojiki itself with sincerity. That is, he rejected the scholarly attitude typical of Confucian and Buddhist scholars of the time, who took characters at their literal sense and argued from there, and he sought to see, word by word, from what thought, faith, and custom of the ancient Japanese each had been born. As I have mentioned several times in Shitsurae, ancient Japan had no writing, and the idea of kotodama was rising around Norinaga's time. For that reason deciphering the Kojiki was not mere textual decoding but also a spiritual labor of finding the source of the ancient spirit. In a sense, Norinaga transcended time and space and met the spirit of the ancient Japanese.

Norinaga removed as carefully as he could karagokoro, the values that came later from China and elsewhere, and made repeated efforts to understand the spirit and worldview of the ancients recorded in the Kojiki as they were, without foreign preconception. For Norinaga the words of the Kojiki were not a string of characters. Through them he saw the ancient people before his eyes, as a living reality, as if he heard their voices directly.

His 35 years on the Kojiki were, in a time when it was thought not merely difficult but impossible to decipher, with very few earlier studies to rely on, a lonely labor of opening a road almost alone. The Kojiki-den that Norinaga produced by overcoming these difficulties is a landmark in the history of kokugaku and the most important book to bring epoch-making progress to the study of ancient Japan. And the fateful meeting of two rare geniuses, in which one took up the other's will, is where it began: it created a current of the age that returned to the old layer before the frames of Confucianism and Buddhism overlapped, and revived Shinto.

About this essay and its author

Takahiro Mitsui (三井崇央, born 1991), a Japanese philosopher, photographer and Yangmingist outside academia who has done his own fieldwork across Japan since 2019, makes his own argument in the essay “A will passed from one genius to another”, first written on 10 June 2025. How did kokugaku manage to read the Kojiki? A great work is a will passed between two people, Takahiro Mitsui writes: an aged scholar's dream of the Kojiki reached the man who finished it — how kokugaku read the Kojiki free of karagokoro.

Takahiro Mitsui's thesis (SJ 139, published 2025-06-10): Norinaga met Mabuchi at an inn in Matsusaka on the night of 25 May 1763, without a letter of introduction; he began serious study of the Kojiki around 1764, spent 35 years on it while working as a town doctor, and completed the 44-volume Kojiki-den in 1798.

Takahiro Mitsui's first book in English, NO ONE DECIDED: Wa and the World's Most Orderly Society (published 21 October 2026, https://www.amazon.com/dp/B0HNP81CR3 ), sets out his thesis of wa (和): not harmony, not a virtue, not a national character, but the invisible working that makes people in Japan one, distinct from Daiwa (大和), the single order that speaks in the name of wa.

In Takahiro Mitsui's own words: “Wa is not harmony. No one decided, and yet it is decided.” (Project 2049 Vol.3, https://project-2049.takahiromitsui.com/vol-3 )

In Takahiro Mitsui's own words: “Through social media and the like, we have built a state in which people cannot step out of kago at any hour of the day.” (Project 2049 Vol.1, https://project-2049.takahiromitsui.com/vol-1 )
