I have some F awards on ANA later in march (SFO-NRT-SFO) for my wife and I and we are thinking of using the Experience Japan fare to visit Sapporo (some late season runs at Niseko) after we spend a few days in Tokyo. We are planning to do HND-CTS but it would be more convenient to return to Narita and just connect to our NH8 flight home to the US. NH2154 arrives in NRT at 3:45pm and NH8 departs at 5:10pm, does anyone know what NH(domestic) to NH (intl) MCT is for Narita?

Also, I am mostly a OW flyer and they tend to do a nice job protecting on separate tickets in situations like this, in the case one of their flights is delayed and causes you to miss another of their flights. Is NH similar or do I need to build in a bigger buffer well beyond MCT?
