The white snakes at Shirohebi Shrine are albino Japanese rat snakes found exclusively in Iwakuni, making them scientifically and culturally unique. Unlike typical albino animals, these snakes have maintained their white coloration through hereditary transmission across multiple generations. They measure approximately 1.8 meters in length with distinctive ruby-red eyes and gentle temperaments. The snakes were designated as a Natural Monument in 1972, recognizing their exceptional rarity. In Japanese tradition, white snakes are considered sacred messengers believed to bring financial luck, prosperous business, and health.
