Seattle to Tokyo is only 4144nm so that might be a viable route especially for routes that would have already had a layover in LAX and/or Tokyo.

The Great Circle mapper is fun for playing "what if" games with potential routes: e.g. here's the direct Seattle-Tokyo routing with dark shading showing parts where flying for 60 mins at 410 knots wouldn't reach an airport. So if that was the ETOPS performance for a Boom aircraft (and I've no idea; I just picked a B777 as an example) then the route would have pass a little closer to Alaska and Sakhalin to keep the possibility of a safe diversion at all times, and that in turn might make the route too long. http://www.gcmap.com/mapui?P=KSEA-RJAA&MS=wls&DU=mi&E=60&EV=410&EU=kts http://www.gcmap.com/mapui?P=KSEA-RJAA&MS=wls&DU=mi&E=60&EV=...
