I have traveled to Japan, Tokyo specifically, on numerous occasions and decided to share some of the things I have learned as I plan my next trip. I am big on convenience. You could say it borders on being lazy, as such, the title of these posts. I woulkd be willing to pay extra for a bit of convenience.
At this time, I can only comment on United and ANA flights that I have flown on. Haneda is much closer to Tokyo than Narita. In comparison, a 15-minute local train ride over a 1-hour express to reach the Yamanote line. The airport monorail or Keikyu line are available or a taxi should the trains stop running past midnight. Over the last few years, Haneda has opened up to international flights. These flights arrive at extreme times, early morning or late evening. The first flight arrives around 6am and departs from the US around midnight. For those that can sleep during the flight, it may help to reduce jet lag as you can get a good nights rest and awake upon landing ready to hit the ground running. That was my thought at least. Even as late as the departure was, sleep would be elusive and I was awake the whole time except for 1 or 2 15-minute naps. After landing, I had at least 8 hours before I could check in. Half-asleep, I busied myself until then.
The other flight departs around midnight to land at 1030pm. With this, I get my bags, go to the hotel to check in, then fall asleep. This schedule worked out better for me last year and its the same one that I will follow this year. Since I am tired by the time I land, it is easy for me to get some sleep so I can be ready to go out the next day. Departures from Haneda that I have taken, leave shortly after midnight. This gives you the whole day to do last minute things before you head home. Time enough to grab a nice dinner in town as well. Could possibly save you a nights expense at a hotel.
The flights to Narita take off around 11am to land approx 3pm-4pm at Narita. These are some of the busiest hours of the airport. Customs lines can be long. Most times, you will get into Tokyo around dinner time. If you are up to it, catching some night life. Flights from Narita depart around 5pm-6pm. Then you have to factor in the transportation time to the airport and buffer time while at the airport. This can make for a harried morning trying to get everything packed. You could probably squeeze in lunch before getting on the train. Easy access to Narita provided by the Narita Express or the Skyliner. I have only ever taken the N'ex.
