Omizutori' is officially called Shunie (a Buddhist mass held in February by the lunar calendar), where people repent and confess all their sins and mistakes to Juichimen Kannon, the hall's principal image, and pray for their happiness and prosperity as well as their country's peace and stability.
「お水取り」は正式には修二会（しゅにえ）と言い、二月堂本尊の十一面観音に対してもろもろの罪や過ちを懺悔し、国家の安泰と人々の幸福を祈る行事である。
