The great circule route will take the flight over the north Pacific. One's perception of distances in the far north is often distored by the Magellan projection maps. The reality is NRT is only about 6.5 hours from ANC, and there are several alternates in the Aleutians, although weather tends to be a challenge there. I don't think ETOPS 180 will require any route alternation. PHL-NRT is not appreciably different in length than JFK-NRT, DTW-NRT or DIA-NRT, all of which has been flown non stop regularily by JAL and NW long before the 747-400 was available. Well within range of 777IGW or A330-200.
