Koyasu Jizo Bosatsu is a form of Jizo Bosatsu (Kshitigarbha), a widely venerated bodhisattva in Japanese Buddhism known for compassion toward children, travelers, and those in suffering. The "Koyasu" (safe childbirth) designation reflects a folk tradition in which this figure is invoked by expectant mothers and families seeking protection and ease during pregnancy and delivery. Statues and shrines dedicated to Koyasu Jizo are commonly found near temples throughout Japan, often visited as part of local customs surrounding childbirth and child-rearing.
