Bon Odori originates from the story of Maha Maudgalyayana (Mokuren), a disciple of the Buddha, who used his supernatural powers to look upon his deceased mother. He discovered she had fallen into the Realm of Hungry Ghosts and was suffering.[3] Greatly disturbed, he went to the Buddha and asked how he could release his mother from this realm. Buddha instructed him to make offerings to the many Buddhist monks who had just completed their summer retreat, on the fifteenth day of the seventh month.
