Originally a holiday created in honor of the goddess Irashi, Pasora is a couples' holiday that has since been adopted by many people across the world.
The original intent of the holiday was to show devotion to Irashi by consummating relationships in fits of furious passion, therefore ensuring the continuation of bloodlines. Children borne as a result of this day were often considered to be offerings to Irashi, and generally favored by parents.
However, in recent times, the holiday has been corrupted somewhat into a mockery of its original purpose. Couples began to use the holiday to confess their love and express it. It is now popular to send gifts to lovers on this day, and the more utilitarian purpose of growing a family has been lost to time.
