Awesome trip, and congrats. We just recently got back from our honeymoon in Asia, and we're considering doing the Maldives next winter! I think I flew on the same flight from BKK-NRT in J, and it was perfectly fine for the amount of time we were on it. Make sure to mention you are on your honeymoon. We ended up with a huge bag of candy and a toy plane for the future child we apparently will have (according to the flight attendant). Have you made any restaurant reservations in Tokyo? If not you definitely should, ask your hotel concierge to help you. I'm very familiar with the Tokyo food scene if you would like some recommendations. The Sakura lounge in Narita is great, though it does get crowded. Looking forward to your report.
