As so many foreign tourists visit Japan nowadays, you might have heard of this one unique Japanese invention or you've already experienced.
The invention is a taxi door. What's special about it? It is automatic and you don't have to open the door yourself. The driver opens it for you using the lever at the driver's seat. The only thing you have to do is to wait for the door to be opened.
Today the automatic door has got very common in Japan but yet there are also still a few taxies with manual doors. To avoid confusing customers, taxi campanies put the stickers on the windows so that customers can know whether the door is automatic or not.
When you take a taxi in Japan, you can know whether the door is automatic or not by the sticker or simply you just wait for a second and see what happens!
