Highways
General
Routes
The routes of the highways changed little-by-little over time, often by improvements to get around natural barriars. Most of the highways below are still in use and are commonly called by their old names. One normally talks about "Kôshû Kaidô" rather than NR (national route) 20, for instance. The modern expressway network does not follow the old routes, however.
The following route descriptions are not meant to be detailed or to strictly follow Edo-period or earlier routes, but to allow someone with a modern map see how the roads went and what the major barriers were. The indication of the expressways is just to give the reader a general orientation, as those are usually easy to find on maps.
