Brief Personal History
He became a foster child after the adoption of Tadakata MATSUDAIRA, who had been adopted to be the successor to the ruler of the Oshi Domain, was dissolved.

He succeeded as family head and became the lord of Domain after Tadakuni MATSUDAIRA (Musashino Province, Oshi Hanshu) in 1863. His major achievements were as Kyoto Guard and the suppression of the Tengu Group at Mito Domain. After the Battle of Toba and Fushimi in 1868, the domain was divided over whether to rebel against or follow the new government and Tadazane could not unify the domain's opinion. However, with the help of the retired Tadakuni, the domain decided to follow the government and Tadazane gave in to the new government troops. He died at the age of 30 year, soon after his foster father, Tadakuni's death in 1869.

Hogo (posthumous Buddhist name): Reigeninden junkei ryoutaku daikoji. His grave is at the Myoshin-ji Temple school of the Rinzai sect, Kaitosan, Tensho-ji Temple in Saitama, Gyoda City, Saitama Prefecture.
