The paper describes the activities of carpenters engaged in construction at Koyasan Temple. In the late 11th century, carpenters from Koyasan Temple worked on small construction projects, while carpenters from Todaiji Temple worked on large ones. In the middle of the 12th century, Kyokou participated in construction projects jointly with Sankou. For the construction of Amanosha Shrine, completed in the early 14th century, a Kyokou was given of Sodaiku. Since then, the Sodaiku was inherited from generation to generation by a carpenter from the Kyokou guild. Such inheritors were entitled to bear the name Saemonjiro.
