@matigo one of my favorite people to follow is Craig Mod, who while staying in one place (Japan), nevertheless keeps "moving" or "traveling" by doing super long walks. I think he's inspired by Basho and Narrow Road to the Interior.
My point is - you might have a good idea on your hands. Of course, the economics of it is something you'll have to understand - you need patrons for this sort of a venture. There's already a flood of westerners who live in and explore Japan. There are plenty of Japanese camping youtubers. There are others who visit Japan for hiking, camping, etc (I loved go4x4media's Japan video).
I'm just saying that you need to find your niche. Maybe it's solo travel, maybe it's "travel with Ayumi", or maybe it's "efficient travel" with a focus on Japan, but maybe extending it a few years down the line to other countries.
Also, you have a captive audience here on nice.social who interact with you daily. A good place to start exploring this idea.
