Shoshinsha mark
The shoshinsha mark (初心者マーク, beginner's mark) or wakaba mark (若葉マーク, sprout mark), officially Beginner Drivers' Sign (初心運転者標識, Shoshin Untensha Hyōshiki), is a teal and yellow V-shaped symbol that beginner drivers in Japan must display at the designated places at the front and the rear of their cars for one year after they obtain a standard driver's license. Drivers who consider themselves beginners may continue to display the sign, even after the period of a year.
