Right lane is for overtaking only…
Did you notice the greenish shoe prints on the left lane?
In Japan, it is customary (or even mandatory?) for people to stand on the left side when using escalator (or in this case, a travelator). By doing this, people who are in a hurry can take space on the right to walk by.
Can you see the green shoe prints?…
I took these photos in Narita Airport, but the same ‘rule’ applies throughout at least Greater Tokyo Area (Kanto), if not whole Japan — except in some area including Kansai (Kobe, Kyoto, Osaka); they are applying “keep right” instead of “keep left”.
Interesting, no? What’s the custom in your country?
