What shape is Japan’s standard stop sign, unlike the octagonal U.S. stop sign?

Japan’s standard stop sign is an inverted triangle.

Japanese stop signs are distinctive because their red signs use a downward-pointing triangular form rather than the octagon familiar in the United States and several other countries. The Japanese word 止まれ, meaning “stop,” appears on the sign, and newer signs also include the English word “STOP” to assist international drivers.

The inverted triangle is strongly associated with stopping in Japan, while triangular signs in many other countries usually warn of hazards. This difference is one reason visitors should learn local sign conventions rather than relying only on shape recognition.

At a Japanese stop sign, a driver must come to a complete stop before the stop line or intersection and confirm that it is safe to proceed. The sign’s design is part of Japan’s national road-sign system, which has developed alongside international standards but retains country-specific features.
