The Four Great Men of Kokugaku, a group of scholars pivotal to mid-Edo period Japanese intellectual history, counted Kamo no Mabuchi among their number. Born in 1697 in the village of Iba, he dedicated his career to the rigorous study of ancient Japanese literature and the linguistic roots of the nation, shaping national discourse through his research.
Early Development and Education
Born as the third son of Okabe Masanobu, Mabuchi spent his formative years in Tōtōmi Province. In 1707, he initiated his training under Sugiura Kuniakira, a practitioner of kokugaku who operated a private academy in Hamamatsu and served as a disciple of Kada no Azumamaro. Mabuchi moved to Kyoto at age 37 to pursue direct instruction under Kada no Azumamaro. After his teacher died in 1736, he relocated to Edo in 1738 to establish his own teaching practice.

In 1746, Mabuchi secured a professional position with Tokugawa Munetake, the leader of the Tayasu branch of the Tokugawa clan. He maintained this role for 14 years, concluding his service in 1760. Four years later, he settled in the Hamachō area of the Nihonbashi district. There, he opened the Agatai academy, where he spent his final years focusing on writing and mentoring a wide circle of students, including Motoori Norinaga, Arakida Hisaoyu, Kato Chikage, Murata Harumi, Katori Nahiko, Hanawa Hokiichi, Uchiyama Matatsu, and Kurita Hijimaro.
Intellectual Contributions
Mabuchi is credited with the initial identification of Lyman's Law, a principle governing rendaku in the Japanese language. His academic output centered on the theory of magokoro, which he identified as essential to Japanese history. His primary written works include the Kokuikō, which outlines his veneration for the poetic style of the Man'yōshū, alongside the Engi shiki noritokai, Goikō, Man'yōkai, Kanjikō, Nihimanabi, and Noritokō. These texts provided commentaries on norito, kagura, the Tale of Genji, and various liturgical prayers.
Legacy and Final Years
A notable intellectual encounter occurred in 1763, when Motoori Norinaga visited Mabuchi during a journey to Ise Shrine. Their single night of discussion in Matsuzaka remains a significant moment in the transmission of his ideas. Mabuchi died in 1769 in Edo at age 73. His remains are interred at Tōkai-ji Temple, a site designated as a National Historic Site in 1926. A memorial museum currently stands at his birthplace in Hamamatsu.
