Born the third son of Tokugawa Yorifusa, lord of Mito, he was later chosen as heir over his elder brother.
Wild in youth, he was deeply moved on reading the biography of Bo Yi in the Chinese history Shiji and turned to study. He reportedly also agonized over succeeding ahead of his brother.
He opened a historiographical office at his Edo residence and began compiling the Dai Nihonshi, a history of Japan; the Mito domain continued the project into the Meiji era.
On his father's death he became lord of Mito. He made his elder brother's son his own heir, honouring his duty to his brother.
He reformed the domain's government, banning junshi and reorganizing temples and shrines.
He named his historiographical office the Shōkōkan and gathered scholars from across Japan to research sources.
He retired as lord and lived at the Seizansō in Hitachi. The tales of "Mito Kōmon" travelling the land punishing evildoers are later fiction.
He erected a monument to Kusunoki Masashige at Minatogawa in Settsu, inscribed "Alas, the grave of the loyal retainer Lord Kusunoki".
He died at the Seizansō. The reverence for the emperor spread through the Dai Nihonshi (Mito learning) strongly influenced late-Edo loyalist thought.
