Honda Yasunori served as a bushō and daimyō from the Azuchi-Momoyama to early Edo periods. He was the second lord of the Mikawa-Okazaki domain and the second head of the branch of the Honda family descended from Honda Hirotaka.
In 1579, Yasunori was born in Tahara in Mikawa Province as the eldest son of Honda Yasushige, the first lord of the Mikawa-Okazaki domain and a retainer of the Tokugawa clan.
In 1591, Yasunori attended his coming-of-age ceremony and received from Tokugawa Ieyasu one of the characters in his name. In 1601, he was invested with the titles of Junior Fifth Rank (Lower) and Governor of Ise. In 1611, after the death of his father, Yasunori inherited the headship of the clan.
In 1614, Yasunori participated in the Winter Campaign of the Siege of Ōsaka, attacking Aoyaguchi from a sandbar between the Shimano and Yodo rivers. After the war, following a settlement between the Toyotomi and Tokugawa clans, Yasunori joined Matsudaira Tadaakira and Honda Tadamasa to serve as magistrates overseeing work to destroy the stone walls and fill-in the moats surrounding Ōsaka Castle. In 1615, when the settlement collapsed, triggering the Summer Campaign of the Siege of Ōsaka, Yasunori deployed in the division of the right wing led by Maeda Toshitsune. Yasunori fought valorously against Ōno Harufusa, a commander on the side of the Toyotomi.
Afterwards, Yasunori engaged in the construction of Okazaki Castle. In 1623, he accompanied Tokugawa Iemitsu, the third shōgun of the Edo bakufu, on a visit to Kyōto. Later, he fell ill and, on 9/25, died. He was forty-five years old. Yasunori was succeeded by his eldest son, Honda Tadatoshi.
