Hello, I have a question for you frequent fliers out there. I am currently planning on a business trip to China in mid - late Oct and my return trip has a connecting flight in NRT. My itinerary is below:


ALL NIPPON AIRWAYS SHANGHAI TOKYO 1015A 215P
NH 922 WEDNESDAY PUDONG INTL NARITA
Z BUSINESS TERMINAL 2 TERMINAL 1
NON SMOKING MEAL NON STOP
RESERVATION CONFIRMED 3:00 DURATION



CONTINENTAL AIRLINES TOKYO HOUSTON TX 355P 150P
CO 6 WEDNESDAY NARITA G.BUSH INTERCO
Z BUSINESS TERMINAL 1 TERMINAL E
DINNER NON STOP
RESERVATION CONFIRMED 11:55 DURATION

Will the small layover in Japan be enough to change flights? Also, will I be required to go through Japanese customs, immigration, or security? This is my first time taking a non-European flight. Any help would be appreciated! Thanks
