Sounds like this reporter pissed off the Japanese side and the American side is enforcing it.
For those that don't know, Misawa Air Base is shared with the USAF and the JASDF. They each have their own portion of the base, though the American portion is larger by a magnitude. They can complain about the ban all they want, it ain't gonna be lifted.
Also FYI, JAL uses the runway and has it's own gate to the flight line.
