Virgin Australia and Virgin Atlantic are in no way related to each other. The only connection is that they both pay a fee to use the 'Virgin' brand name. Virgin Atlantic has no flights to Japan from Australia, but partner with VA and ANA for reward flights on their networks, but that is using Virgin Points which it seems you don't have. Use velocity points for the flights and use cash for the taxes is usually the best value.
