Hello D&F
Air Japan don't own any of their own aircraft. They dry lease machines from ANA. ANA have 19 767 300 ER's.
Air Japan have approx. 60 foreign pilots and 20 ANA pilots, with plans to expand to 100 or more foreign pilots.
As AJX grows, it will take more of the 767 flying from ANA, international flights.
Sorry if the answer's a bit vague but that's how the system works here.
