The number 88 holds great significance in Japanese culture due to its association with Buddhism, luck, and spiritual growth. It originated from counting only the impure desires in Buddhism, and is considered lucky because it sounds similar to the word for prosperity. There are several pilgrimage routes in Japan that include 88 temples or shrines, collectively known as the Shikoku Pilgrimage, which is believed to bring good luck and spiritual benefits. The number 88 is often used in business and advertising, and is deeply ingrained in Japanese culture.
