A Japanese triangular stop sign
Red means go faster! No, wait, that's not right. Red means stop!
In Japan stop signs look like this. However, many places the word "Tomare" which means "Stop!" in Japanese is just painted on the ground without a sign accompanying it. This confused me when I first began to drive, because in America any intersection which requires a stop includes a sign. Not so here, but recently Japanese city planners have been trying to beef up there usage of signs. Still, small country villages or even the outskirts of Kumamoto itself, you can find lots of stops with no signs. Drivig becomes a full time job, and if you haven't read my post on driving which I made last month, go check it out!
