For my stay in Tokyo, I chose to stay at the airport. While the first part of my plan (checking in early to freshen up) did not go quite as expected, it was convenient for the second half of my plan: Being able to get to the airport at a leisurely pace for my late morning departure.
As a Hilton HHonors gold member, I was given a voucher for a complimentary breakfast at their restaurant. The buffet was a vast collection of Japanese and Western dishes, but I chose to not take photos as it was rather busy and I didn’t feel like explaining what I was up to.
