[Tagging] Named junctions

[tomoya muramoto]

In Japan, a name plate is attached to a traffic signal, but the name is
widely recognized as "junction" name. So I think it's reasonable to tag it
as a junction.

However officially (legally) the name is "place" name. It causes some
problems.

Small problem: No junction

There is traffic signal with name and zebra zone, but no junction here. Is
it a junction name or a signal name?
(I think it can be treated as a junction name to keep consistency)

Severe problem: Different names
https://www.google.co.jp/maps/@43.0932299,141.3406141,3a,75y,36.3h,85.98t/data=!3m6!1e1!3m4!1sXMdPZfgudt0fNJT3iY-l2w!2e0!7i13312!8i6656
It's not so big junction. There are four physical traffic signals.
However each name of traffic signals are different, 北27西6, 北27西5, 北26西5,
北26西6(北=North, 西=West). Because they are "city block" name.
I don't have any idea to map them correctly.
