He was the first son of Nakai Shuan (1758 d), one of the Kaitokudo"s two founders, and was influenced by his teacher and mentor Goi Ranju.
He became the administrative head of the Kaitokudo in 1797 during the Tokugawa era in Japan. They both focused on the epistemological study of virtue in the merchant class of Tokugawa Japan, furthering the work of Goi Ranju and consolidating previous thought around the Kaitokudo school. Together, through their scholarly works they would bring a level of prestige to the Kaitokudo with their study of virtue.
Ultimately they wanted to reconcile merchants and contemporary views of merchants in Tokugawa society.
The first son of Nakai Shuan, one of the two main founders of the Kaitokudo, he was just as adept in the external bureaucratic maneuvering of administration as his father. He attended the Kaitokudo from a young age, where his interests in the epistemological study of virtue were cultivated by the scholar Goi Ranju.
Both felt that education should be their primary concern rather than working on the side to supplement their income, something symptomatic of many Jusha who preferred to operate pharmacies on the side. This earned them scorn from many of the Osaka merchants who contributed to the school"s cost of operation.
Shuan left a fund of twenty kan to insure against emergencies to be managed by Chikuzan.
In this way Shunro would be responsible for formal activities and Chikuzan would be in charge of financial activities "to assure the immortality of the academy-Eitai sōzoku no yō." (Najita 151-52). Chikuzan whole-heartedly denounced Ogyū Sorai and contended that all people have potential, even commoners could become scholars, while he also denounced religion and superstition.
An extrovert known for his bureaucratic skills and his firm precise kanji, Chikuzan was vastly different in demeanour to his brother Nakai Riken, although their underlying epistemologies, beliefs and degree of tenacious individualism were similar.
