I am flying CPH-PEK-TYO in C.

The best connection is with Air China, 80 minutes after arrival. This takes me to NRT and is a 738 with US domestic F class style seating.

If I wait 2.5 hours more then I can fly to HND on ANA. Originally (a few days ago) it said that it is the 787. But I looked on Expertflyer and there it is a 763. Unlikely to get the 787 back by June 18, eh? I imagine that this would be a longhaul 787 and not a domestic config?

I imagine that the Air China (?) lounge in PEK is not that great? Does it have a rest area?

Any suggestions?
