Okomu no kata, also known by her Buddhist honorary name Hôshin-in, was a concubine of Tokugawa Tsunayoshi.
She gave birth to Ienobu's first son, a boy named Iechiyo, on 1707/7/11, and was promoted within the hierarchy of the Ôoku as a result; granted the status of oheya, she was given her own room within the Ôoku compound. However, little Iechiyo died two months after being born.
