You’re walking along a path and another person approaches from the opposite direction.
Do you tilt your head to signify which direction around them you intend to go? Is that head tilt understood by others?
Should we start pointing also?
Install hand blinkers?
No, never heard of people doing that and most likely wouldn’t understand it. I generally just pass people on the right, seems to be what 99% of people are doing as well so it’s rarely an issue. If it’s a really narrow path I might just step to whichever side is safer and let them pass.
I choose right too because America drives on the right. Interestingly, Japanese tend to walk on the right too despite driving on the left.
Some recreational trails will have signage reminding people to keep to the right unless passing around someone
I feel like that’s generally understood to be the standard
The left vs right thing in Japan depends on the city. Particularly for escalators. Some places will have signs that say to stand on left while others say to stand on right. Others also say not to walk on the escalator, but people always ignore that.
