"We do our best to confuse the foreigners.."
Article about the "green frog", the train car which was for many years prominently in Shibuya, next to the famous Hachiko statue. In Japanese, "green frog" is 青ガエル. 青 is actually "blue" but also used for "green". So "the traffic light turned green" in #japanese is expressed "青になりました", also using the kanji for "blue".
