I've been looking at going to Australia next month and have been looking at entry requirements for Australia and Japan (since it looks like I may have to transit through Tokyo to make it work). Does anybody have experience non-reving through Japan or Australia? Is not having a confirmed return or onward ticket an issue for entering either of these countries (I hold a valid US passport)? Any tips or tricks you guys know? I'm hoping the APC brain trust can impart some wisdom to help this trip go smoothly.
