I just go for a simple "torimasu" but yeah, good point. Don't want to scare the old folks with words. That's what my face is for.Migi/hidari torimasu
Works for me.
I found that if I don't inform them which side I'm approaching from it causes panic and suffering in the older folk and a general wiggling right to left from the younger.
I just whistle loud.
I find saying right or left (in Japanese) confuses them - as they do not know if it means you are going left or right or they are to move left or right.
Nope, get it all the time in Japan, people hear right or left and as they turn their head that way the body or bike invariably follows. Walkers and runners are worse than cyclists.Never once had this issue.
It has always meant "I'm passing on the right". That's it, no confusion ever.
