I pulled-up the seating chart from NRT to BKK for a random date in August. It is this configuration (which beats the heck out of what they were using on a red-eye from SIN to NRT in C):

Pitch seems to be similar to UA in E- based on the seating charts; however, NH is 8 across vs. 9-across on UA.

The return to NRT departs just after mid-night, however, and the day-time flight on 22 August at least is cradle seats in C in a 2-3-2 configuration.
