I was under the impression that that the names would be the same in all directions (as the signal set itself is named), as all the signals I have seen and surveyed all are this way. Tomoya showed me that towns in Hokkaido (and only in Hokkaido, it seems) have names based on what "grid segment" is being entered, which means each signal in the set have a unique name (4 signals in a simple junction). The solution that other map makers have used- Google, yahoo, Mapion, etc - is to list the values as a single label for the entire junction, so it is in line with the rest of Japan and compatible with routing software that expects the signals to have a single name. I did a quick check across Japanese urban centers, And this issue does not affect (I estimate) ~99% of signals in Japan, and not present at all outside Hokkaido (AFAIK). Sapporo and surrounding cities probably have several hundred signal sets that are affected by this. I wrote this information up in a previous post with a little more detail on the issue.
