"右側通行" (yuu-soku tsuukou) refers to the practice of keeping to the right side of a road or pathway while walking or driving. This rule is commonly observed in many countries to ensure smooth traffic flow and enhance safety for pedestrians and vehicles. By adhering to this guideline, individuals can avoid collisions and navigate crowded areas more efficiently. In places like Japan, where "右側通行" is a standard, it is important for both locals and tourists to follow this rule. Public transportation systems, such as subways and buses, also encourage passengers to keep to the right to facilitate easier movement and boarding.
