SFO to NRT via PVG (on Air China) - 2 hour layover enough?
I'm looking at various open-jaw itineraries on ITA Matrix from SF Bay Area to Tokyo, and then from KIX back to SF Bay Area, and the cheapest options are on Air China via PVG or PEK. For example:

This one has a 2 hour layover in PVG. Is this sufficient? What about PEK?
Obviously, I don't want to miss my connecting flight, but I'll be spending the first few days of my trip in Tokyo, so even if the connecting flight gets rescheduled or delayed I won't be in too bad of a shape.
