Who is Soseki's Mother, Omitsu from Kokoro and what is their importance?

Omitsu appears to be the more traditional wife of Japanese culture. She worries over her husband's health but, succumbing to his will, does not pressure him to slow down. Uneducated with the world and perhaps in her blind hope her husband will recover, Omitsu mistakes his deteriorating health for progress. When Soseki's father begins to lose control of his faculties, Omitsu shows her loyalty to her husband by reminding his sons of the formidable character he used to be. Omitsu also appears conflicted when she speaks to her son. On one hand, she wants him to find a good career in order that his father is satisfied before his death. However, when Soseki informs her he must go to Tokyo to find a position, she tells him he cannot leave with his father in his condition.
