The tactics used to deliver a bomb in Germany would have had to be different than Japan. The Luftwaffe still had some fighters operational till the last month of the war in Europe. I would think that stopping one large B-29 trying to deliver one bomb to a target would be easier to shoot down than 1000 B-17s on a conventional mission.

I believe the Japanese also had fighters active at the end. They just didn't think a single aircraft, they thought it a reconaisance plane, worth engaging.
