I think NRT MCT international to international is 60 min. If no delay in SFO, I think we'll be fine. But ... looking at Flightaware, the JAL57 segment from SFO to NRT has 37 late arrivals out of flight history of 82 days. Late by 15 or so min may not be an issue, but there are a few where arrivals were pushing beyond 6pm. The non-stops to SIN after JAL scheduled flights are ANA and SQ, and SQ is the latest one at 7pm.
If - God forbids - my flight arrived late due to delay by JAL, and there is no other flight out of NRT that evening, what do we do? We do not want to get quarantined in Japan and it is too late to change our tickets since this is an award reservation.
If you look at the Asian evening departure bank, you will see that they are delayed about as much as the inbound flights from the US. The generally hold them to try to make sure there are zero misconnects.
There is no transit security check when arriving from the US, so they really only need 10-15 minutes from you leave the plane until you reach the next, if push comes to shove.
