On August 15, the 10th memorial service for the late Mrs. Masa Nakayama—the former Shinbashira’s wife—was solemnly observed in the Memorial Hall with the Shinbashira presiding as chief officiant. Attending the ceremony were members of the Nakayama family and their relatives, Church Headquarters’s staff members, head ministers of directly supervised churches, diocese superintendents, general church head ministers, Yoboku, and other followers. A total of 28 marquees were set up in Church Headquarters’s Inner Courtyard and were filled with large numbers of followers including staff members of the High School Division of the Students Training Course, which had closed after the morning service on that day.
Shortly before 11:00 a.m., the Shinbashira and other officiants left the Staff Quarters for the Main Sanctuary and the Foundress’ Sanctuary before proceeding to the Memorial Hall. The ceremony then took place in the Memorial Hall, where the Shinbashira read a prayer, expressing his gratitude and respect for Mrs. Nakayama’s painstaking efforts and accomplishments.
