Shōryōuma (精霊馬) refers to a traditional custom in Japan during the Obon festival, which is typically held in August. The shōryōuma is a "vehicle" made to welcome and send off the spirits of ancestors who are believed to return to visit their families during this time.

Usually, the shōryōuma takes the form of a horse made from straw. In some variations, a cucumber horse is made to symbolize a speedy journey, while an eggplant cow is created to represent a slower, more peaceful return. Though the practice of making shōryōuma may differ by region, it is always a deeply respectful gesture honoring the ancestors.
