Stop Signs in Japan

  • According to the international standards, a stop sign has an octagon shape, but it has an inverted triangle shape in Japan.


    Originally, Japan had used an octagon shape for the stop sign following the US, but in 1963, we changed it into an inverted triangle that had been used in Germany, because the shape had a high visibility.

    However, in 1968, since an octagon shape was decided as the international standards, Germany changed stop signs into octagon shapes.

    Finally, only Japan has been left behind.

    Also, recently the Japanese government seems to consider changing the stop sign into the octagon shape in concert with the Tokyo Olympic in 2020.

    Since the number of stop signs on Japanese roads is about 1.7 billion, it will cost 22.5 billion yen (192 million dollars) to replace all of them.

    ※Sorry, the number 22.5 billion was wrong, and the correct number is 25.5 billion (217 million dollars).
