Japan '86?

Since Queen loved Japan as they loved Queen, I've always wondered why no Japanese cities were included in the Magic Tour?  Could it be:
1.  It was too expensive to haul the tremendously large rig there?
2.  They simply didn't want to tour the world?

Any thoughts or facts as to why this didn't  happen?

I've wondered the same thing

Fred exhausted physically?
In part 2 of the documentary Roger does mention he got "The vibe from Freddie he felt he wasn't maybe able to do any more"
and "I think he had an idea he might not be terribly well"
