Competitive Strange/Origin

Origin
Health and Sports Day, 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 held in Tokyo, and exists to promote sports and an active lifestyle. As Health and Sports Day is a day to promote sports and physical and mental health, many[citation needed] schools and businesses choose this day to hold their annual Field Day (運動会 Undō-kai?), or sports day. This typically consists of a range of physical events ranging from more traditional track-and-field events such as the 100 metres or 4 x 100 metres relay to more uncommon events such as the tug of war and the Mock Cavalry Battle
