Marc-Tobias has been visiting Hiroshima in Japan and shred these awesome street maps that he spotted. He said:
“As usual in Japan streets are unnamed. To add confusion many
shops are stacked and not next to each other (‘3F’ means 3rd floor)I saw only those two sheets. Unclear who made them, which purpose,
if they’re updated. I don’t think people use them for navigation.”Despite the weirdness (to us at least) of the Japanese addressing system people manage to find their way, mail and goods get delivered. Clearly it works.
