A blue disc carrying the arrows a driver may follow.
Also known as: Permitted directions Japan, No turn except as shown Japan
Restricts a Japanese junction to the movements shown, prohibiting every direction the arrows do not draw.
Permits only the movements its arrows show and prohibits all others.
Contexts: Road signage
States a prohibition by drawing what is allowed, which is why it is carried on a blue disc rather than a red one: the Japanese schedule reserves red for what a driver must not do and blue for what a driver may or must, and this sign is deliberately filed with the second.
Contexts: Road signage
A disc in a solid tone containing one, two or three arrows in a contrasting tone, each pointing along a direction that remains open.
