I did a quick look around, and this signal-grid naming issue seems to be pretty big, but only in Hokkaido. I never noticed this, as I have not been to Hokkaido yet.  several cities up there (Sapporo, Chitose, Obihiro, etc). all have this issue: they use different names on each signal of the intersection signals to show what grid section you are entering, which means people going through the junction in different directions see different signal names.   There are probably several hundred signal sets in Hokkaido that are named in this manner (a ton of individual signals). 

Checking out cities on the Main Island Honshu, as well as Shikoku, Kyushu, and Okinawa all don’t seem to have this grid issue. I couldn’t find one outside Hokkaido. 


I spent 20 seconds in each city, (And I have visited 17 of them)  looking over a high zoom level for these odd signal names, but I didn’t see any.  Maybe there is a few oddly named signals in the following cities, but it seems like they use a standard “one name, one set of signals” idea for the named signals in their downtown areas. 

 This list covers all of the larger cities in Japan, besides Sapporo. 

So I’m guessing this grid issue is related to Hokkaido’s long time territory (-do) status (though that is just a guess), and not really an issue in the rest of Japan.


But since there are several thousand individually named signals in hundreds of sets, then we need to:

- come up with a solution that can handle this issue (1 icon, 4 labels) 

or

 - follow the route of google/Zenrin/Mapion/Yahoo and make a single name with the different high/low grid values for the set (1 icon, 1 label).
