Luggage by color
When your flight is over, you find yourself standing around with the rest of the passengers waiting for your luggage to appear. It can take a while and you often almost take someone else’s luggage by accident because it looks so much like your own. When it finally comes you are glad but wish the process was easier.
Well with the Japanese, they will sometimes color coordinate everyone’s luggage after the flight is over to make it easier for people to find their suitcases. You can just look at the colors everything is lined up in until you find your property and leave. No more mistakes and time wasted.
