Moerai is a traditional Japanese practice that involves the use of fire to purify and bless objects or spaces. This ritual is often performed during festivals or special occasions, where participants gather to create a sacred fire. The flames are believed to carry away impurities and bring good fortune. The term "Moerai" can also refer to the specific offerings made to the fire, which may include food, incense, or symbolic items. This practice is rooted in Shinto beliefs, where fire is seen as a powerful element that connects the physical and spiritual worlds, similar to other rituals in Shinto and Buddhism.
