Japanese Traffic Signs - YAML

Japanese traffic signs are essential traffic facilities installed under the Road Act and Road Traffic Act to regulate and instruct road users on traffic methods, warn of dangers, and guide to destinations. Regulatory and mandatory signs are installed and managed by prefectural public safety commissions, while warning and guide signs are managed by road administrators (national government, prefectures, and municipalities). Each color and shape has specific meanings designed for intuitive understanding by drivers and pedestrians.
