4. Avoid eating on the go when you’re in Japan.
Street food in Shibuya, Tokyo.
In Japan, people don’t generally eat or drink on the go. Fast food sold at street stands and stalls is eaten standing up in designated areas (often marked with lines on the pavement). Drinks bought from the many vending machines available in public places are also consumed immediately and the can or bottle tossed in the recycling bin next to the machine. Similarly, eating or drinking on public transport is considered bad manners, but an exception is made for this on long-distance trains.
