NW operates from Terminal 2 at LAX. Terminal 3 is just used for overflow operations, or in other words when all the gates at Terminal 2 are full (2 is also used by QF, NZ, Hawaiian, etc.)
NW flies LAX-NRT nonstop...in fact it's flight NW1. NW2 is the return flight, routed BKK-NRT-LAX-LAS. LAX-NRT is a 747-200, but the continuation of that flight (NRT-BKK) is a 747-400. LAX-KIX is also a 747-200. DC-10-30s and -40s are used on NW's two daily LAX-HNL runs.
If you're curious, NW operates these routes from LAX:
Hope this helps...if I'm incorrect, forgive me, I've been up since 4am EST today, early BOS-MSP run.
Both NRT and KIX flights from LAX are operated by 742s and have been for the last five years. NW briefly had a 744 on LAX-KIX-MNL aroumd Christmas '95 and before that, NW ended 744s at LAX around mid-92. The777Man

Actually, NW flies the DC10 on the SEA/KIX route and SEA/AMS, so yes, a DC10 can fly quite far. In fact, NW flew a DC10 nonstop from LAX to HKG (empty, of course!) when the aircraft was first introduced into the fleet.
