Year: Day to Day Men: January 21

The Small Silver Medallion

The twenty-first of January in 1598 marks the birth date of Matsudaira Tadamasa (松平 忠昌), an early to mid-Edo period Japanese samurai and daimyō, a feudal lord. He was noted for his skill in the martial arts and distinguished himself in combat by his prowess with the spear.

Matsudaira Tadamasa was born in Osaka as the second son of Yūki Hideyasu (結城 秀康), a respected samurai and daimyō of the Fukui Domain in Echizen. In 1607, he was received in an audience by his grandfather Tokugawa Ieyasu (徳川 家康), the First Shōgun of the Tokugawa Shogunate of Japan, and his uncle Tokugawa Hidetada (徳川 秀忠), Second Shōgun of the Tokugawa Shogunate. Hidetada arranged to raise the nine-year old Tadamasa in the Tokugawa household with Ieyasu’s tenth son Tokugawa Yorinobu (徳川 頼宣), who was four years older.

In 1607, Tadamasa was assigned a fief of ten-thousand koku, and became First  Daimyō of the Kazusa-Anegasaki Domain. He accompanied his uncle Hidetada during the 1614 Siege of Osaka; however, he was frustrated that, due to his youth, he was not allowed to participate in the battle. Tadamasa petitioned his uncle to perform his genpuku ceremony, a classical coming of age ceremony, before the start of the Osaka military campaign in the summer. Hidetada agreed and granted him a kanji, which is a script character for his name, and the court rank of Senior Fifth Rank, Lower Grade as well as the courtesy title of lyo-no-kami.

At the 1615 Battle of Osaka, Matsudaira Tadmasa proved his prowess with the spear; his weapon from that battle  became an heirloom of the Echizen-Matsudaira clan. As a reward for his service in battle, he was given in 1615 a fief of thirty-thousand koku and transferred as Seventh Daimyō to the Shimotsuma Dormain in Hitachi Province. When Shōgun Matsudaira Tadateru (松平 忠輝) was relieved of command and exiled, Tadamasa became Daimyō of the Matsushiro Domain in Fukui with a fief of five hundred-thousand koku.

 In 1626, Tadamas’s rank was raised to Senior Fourth Rank, Lower Grade. He accompanied Shōgun Tokugawa Iemitsu (徳川 家光), the Third Shōgun of the Tokugawa Shogunate, to Kyoto in 1634. During the Shimabara Rebellion in 1637, he was disappointed that he did not receive orders to lead his troops into battle; he visited the battle as a private citizen with twelve retainers. Tadamasa ordered construction work in 1643 for the rebuilding of the Mikuni Harbor as the main port for shipping in the Fukui Domain.

 Matsudaira Tadamasa died at the age of forty-seven in September of 1648 at the domain’s residence in the city of Edo. Upon his death, seven of his senior retainers committed junshi, a honorific suicide ritual for the death of their lord. Matasudaira Tadamasa is buried at the Temple of Eihei-ji in Fukui.

Notes: The koku, a Chinese-based Japanese unit of volume, is equal to about one hundred-eighty liters or one hundred-fifty kilograms of rice. In the Edo period, one koku of rice was considered a sufficient quantity of rice to feed one person for a year.
