As always a great trip report.
Looking forward to Narita -LAX leg.
Having flown JAL FC over a decade ago, I was greatly impressed by the size and general makeup of the FC lavatory, which IMHO would match that and exceed that of Bling Airlines ( other than the on board shower, which was just not offered by any carrier in the 1990s).
Look forward to the next installment of your TR
Cheers!
