I don't understand why this would be interesting.

These "digital nomads" who would travel to Japan for work+sightseeing aren't taking local jobs and don't have a Japanese bank account.

Does Japan want to tax income produced within its borders, regardless of where one is actually a tax resident? Most countries I'm aware of treat people as tax residents if they reside there for more than 180 days a year.
