Cleanliness

Japanese cities tend to be very clean. It’s rare to see trash lying around.

The air quality also tends to be great. No holding your nose up when you exit a building (I’m looking at you, New York city).

Strangely enough there are also very few public trash cans. Consider this when you buy a coffee from a vending machine: it might be a while until you can dispose of the empty can. Look for can bins next to vending machines itself, or ask a convenience store or restaurant to put your trash in their “gomi bakku” (trashcan).
