>>2224304>>2224390>>2224390>>2224399simply not true in a country where almost 70% of the landmass is mountains and forest and the majority live cramped in cities. It's very easy to be alone on the trail even in the west of Tokyo, especially if you have a bike or a car (you see a lot of people with old suzuki jimnies). Obviously the most scenic and touristic places like kamikochi are heavely developped, but that's only if you choose to walk on that trail.
