KIX-NRT by train
Just did the Shinkansen KIX to NRT (usu. it's the other way). Very nice and smooth ride with good views. About same time footprint as DH, but on your schedule. Metro from Namba station to Shin-Osaka. Bought green (reserved) seat ($50 extra but well worth it). One transfer at Tokyo airport to catch the NEX (Narita express) to NRT. You can get off at terminal 1 or 2 to catch Hilton hotel bus. Recommend #2 since its first off the train and last bus pick up before heading to hotel. Fare was 22,680 yen, about $10 under bank. Very helpful people in stations giving directions, etc.
