Sodashi is a pure white Japanese Thoroughbred racehorse who won the 2021 Japanese 1000 Guineas. She was also one of the best two-year-olds in Japan in 2020 when she was unbeaten in four races including the Sapporo Nisai Stakes, Artemis Stakes and Hanshin Juvenile Fillies. In 2021 she won the Oka Sho but sustained her first defeat when running unplaced in the Yushun Himba. The filly returned to the track in August and defeated older rivals in the Sapporo Kinen.

A white horse is born predominantly white and stays white throughout its life. A white horse has mostly pink skin under its hair coat, and may have brown, blue, or hazel eyes. "True white" horses, especially those that carry one of the dominant white (W) genes, are rare. Most horses that are commonly referred to as "white" are actually "gray" horses whose hair coats are completely white. Gray horses may be born of any color and their hairs gradually turn white as time goes by and take on a white appearance. Nearly all gray horses have dark skin, except under any white markings present at birth. Skin color is the most common method for an observer to distinguish between mature white and gray horses.
