Tsukinamisai or the monthly service is the performance of the entire Mikagura-Uta, the sacred songs of the service, which is the service for world salvation.

Generally, mission headquarters and grand churches ( churches with 100 or more under it ) have the monthly services performed on the third Sunday of every month ; other churches perform on any other Sunday of the month.

The monthly service at the Jiba is performed on the 26th of every month, the day of the month in which Tenrikyo was first conceived – October 26, 1838.
