Morozumi Toratō served as a bushō and multi-generational retainer of the Takeda clan of Kai Province.
Toratō was the younger brother of Itagaki Nobukata, a relative and multi-generational retainer of the Takeda. He was first named Itagaki Naokata, and after being adopted by Morozumi Toramitsu, received the name of Morozumi Toratō.
Toratō served as a lieutenant for his older brother, Nobukata, guarding Uehara Castle while others were away, and served as lord of Kashiwabachi Castle in Shinano Province.
In 1561, Toratō inherited the family after the death of his adoptive father, Toramitsu, at the Fourth Battle of Kawanakajima. Toratō then died in 1564, and was succeeded by his son, Morozumi Masamori. Masamori, however, was removed from his position in 1570 following a dispute with Hara Moritane (the son of Hara Toratane). Thereafter, the Morozumi name disappears from historical records.
