- Japanese: 奏者番 (soushaban, soujaban)
Sôshaban were samurai officials in the Tokugawa shogunate who played a primary role in overseeing ritual protocols and ceremonial matters, especially for events held within Edo castle. Sôshaban were typically daimyô from Matsudaira clan branch families, or other fudai daimyô families such as the Hotta clan.
Daimyô and other elites of particular levels of status or rank, when arriving in Edo, were formally met and escorted into the city by sôshaban. During formal audiences with the shogun, sôshaban often played a primary role in directing the ritual actions, announcing individuals' entrances into the hall, and directing individuals when to take certain actions, in the correct manner and the correct order. They also often handled formal letters and other objects in these ceremonies, serving as intermediaries in passing objects between the shogun, other shogunate elites, and the guests. Officials known as kôke served similar functions.
Sôshaban kept extensive records of protocols and practices, and kept these records, known as tedome (手留), in special cases known as tedome tansu (手留箪笥). These were kept in an organized fashion, such that sôshaban could later find records of specific past events, in order to determine or confirm the proper precedents and protocols.
