I'm planning a trip through Japan at the moment and stumbling over the question of transport. I read that I (from Germany) need a translation of my driver's license (which should not be a problem), but also that apart from major highways, it might be difficult for foreigners to navigate the Japanese back-country.
Therefore I wanted to ask whether it's more viable to scratch that plan altogether and instead focus on railways and other public transport to go from place to place. The only obstacle I see in this plan would be that this might "skip over" interesting sights along the way, since you cannot just make a small detour along the way.
Am I wrong on any of those things? Am I putting too much thought on the topic?
