 Furthermore, Princess Kazu retained the customs of the Imperial palace, which caused considerable friction with Lady Tenshō-in.However, she apparently enjoyed such a good relationship with her husband that they are usually called the closest couple out of all the Tokugawa "shōguns", and Iemochi only once took a concubine, which the princess gave him permission to do.Eventually Tenshō-in would reconcile with Princess Kazu, and the "bakufu" submitted to her order to address her as "Kazu-no-Miya-sama", as opposed to the traditional "Midai-sama".
