Thanks everyone. First step toward the trip, I have booked a NC ticket from United.

SFO-LAX in F (UA 1/30)
LAX-NRT in C (SQ 1/30)
HND-CTS in Y (NH 2/1)
CTS-HND in Y (NH 2/10)
NRT-LAX in C (SQ 2/10)
LAX-SFO in Y (UA 2/10)

I was hoping to book NH in First all the way through but thanks to UA Starnet filtering... no go...
