One disadvantage of both NW and UA flights to Asia out of Narita is that they are timed to connect to incoming flights from the US. For the destinations farther from Japan (SIN, BKK, etc.) that means a very late arrival (and a very early departure when returning).

As for the partners, Star Alliance does have more in NRT, with a resulting day and evening flight to the major destinations.

However, JL and NH tickets easily cost Y10-20,000 more from the discounters, as many Japanese prefer to fly their own carriers. Their lower fare classes also sell out much earlier, making them an uneconomical proposition. NW's, perhaps because of its local perception as a no-frills carrier with older planes, are probably the easiest to get.

As for SQ, their pitch in Y is definitely among the stingiest at 31". JL is also pretty tight, NH somewhat better. KE and TG have a generous 34", but very basic seats.

From my experience working in Japan, the only thing you'll want to do inflight is to catch up on sleep immediately. Aim for legroom and less crowded flights

NW also has pretty active marketing in Japan, running more promotions (miles and status) for its local members than UA, which may have its hands tied because of local partner NH. Visit NW's Japan site for details and special offers for its Asian elites; Asian NW Golds get better lounge access than US ones, IIRC (e.g. free Worldclub access in the US).

Also, expect to compete with millions of Japanese Star Alliance elites out of NRT


Which brings up another possibility: ANA's FFP, which is not particularly competitive (miles expire after 3 years, among others), but has two unusual benefits:
- free upgrades to their premium economy section on a space-available basis for their own elites (and full fares), on planes so equipped. Something like 2-4-2 and 38" pitch on a 747, IIRC.
- one of the few remaining airlines to which one can transfer Amex MR miles, if you have a US-issued Amex.
