Welcome to Flyertalk
There is a sticky thread at the top of the forum with lots of advice about ANA -
Virgin Atlantic (VS) Flying Club points redemptions on ANA (NH) - Master thread
I have just done a forum search on Air Japan and from what I can see, the consensus is that you should be able to, as Air Japan is a subsidiary of ANA, but I can't see any reports of success.
All I can suggest is HUCA.
