Health and Sports Day (体育の日, Taiiku no hi^?), also known as Health-Sports Day or Sports Day, is a national holiday in Japan held annually on the second Monday in October. It commemorates the opening of the 1964 Summer Olympics being held in Tokyo, and exists to promote sports and an active lifestyle.

The first Health and Sports Day was held on October 10, 1966, two years after the 1964 Summer Olympics. October was chosen for the unusually late Summer Olympics to avoid the Japanese rainy season, and Health and Sports Day continues to be one of the fairest days of the year.^[1]
