Might need to make this an admin level setting - 99.9999 percent of all traffic signals in Japan are Always "no (left) turn on red" - I have seen maybe one or two in 10 years. This of course is the opposite of the US, where there are a few "no (right) turn on red" signals scattered around (1%?) at major bothersome / dangerous intersections. 

The signal type that really bothers me in Japan is their "red light with green arrows" - meaning the green arrow direction has the opposing traffic stopped, similar to a "red signal+green left turn arrow" in the US  - but imagine that for a "straight" green arrow - a "stop" red light with a "go" green arrow! - Or three "left right straight" green arrows *with a giant red light*!" It confused the hell out of me when I first saw it. This also means that the other directions without a green arrow cannot move (so no left or right turns (below example) regardless, until the red light goes away and a green signal appears or your own arrow is green. 

These are the "1%" signals in Japan - not so many, but often enough to be noticed daily.
