My kid will stop over at Narita Airport in a week. The flight is supposed to arrive by 9pm at terminal 1, but in the past month or so this particular flight has always delayed by 1 to 2 hours. So most likely flight will not arrive until 10pm to 11pm.
I booked a hotel for him at Nine Hours Hotel Airport, located near terminal 2 (http://ninehours.co.jp/en/narita/). However, the free shuttle bus service between terminals 1 & 2 stops running at 10:30pm. (as posted on https://www.narita-airport.jp/en/access/terminal/index.html).
Also, it seems all the public transportation, bus and train, stops severing the Airport about the same time.
After searching on this forum, it was mentioned that it is almost impossible to walk from one terminal to another even they are in walking distance.
What options does he have to go to his hotel/terminal 2?
BTW, My kid speaks English and does not understand Japaneses at all. This is his 1st independent international travel at 17 years old.
