I looked at the tourist flights exITM but the only available nonstop were at bad hours. I would just buy a ticket for around 600 for the 3 of us.
Tshe issue isn't so much the cost as the time. Looks like an 1130 departure from Kyoto puts us into Narita by 1530 in time for the 1700 flight. 4 hours.
Any clue as to how long it would take to get from Kyoto to ITM?
