This article explores the long-standing convention of why track events, particularly in athletics, are run counter-clockly, or to the left in Japan. It delves into the history, the physiological reasoning, and the cultural norms surrounding this curious phenomenon, drawing insights from academics, athletes, and sporting officials. The piece also casts a wider global perspective, questioning if this practice is universal and how different nations approach this athletic tradition.

In Japan, people pay attention to historical norms and traditions, even in sports. The left-turn rule in track events is not just accepted blindly but is of genuine interest as it's part of a larger cultural pattern. The physiological aspect, such as the heart being located on the left side, is often brought up, linking sports practice to natural human design.

In the US and EU, the same counter-clockwise tradition exists in track events. Some suggest this practice is due to most people having a dominant right leg, so turning left allows better balance and speed. While there is interest in the topic, there is arguably less press coverage compared to Japan, reflecting the specific cultural interest Japan has in tradition and norms.
