Matsudaira Tadayoshi

Matsudaira Tadayoshi (松平 忠吉^?, 18 October 1580 – 1 April 1607) was the fourth son of Tokugawa Ieyasu with his concubine Saigo no Tsubone. When his mother died, he and his brother were adopted by Lady Chaa. His full brother, Tokugawa Hidetada, was the second shogun. Later, Tadayoshi was adopted by Matsudaira Ietada and succeeded him as the second lord of Oshi Domain. At the Battle of Sekigahara, he was attended by Ii Naomasa and was therefore at the forefront of the fighting. He was given Kiyosu Domain and remained there until his death at 1607. He was buried in Shinnyo-ji in Kakegawa.
