You have to turn on expert mode in the UA MP user settings area - and then search each flight segment separately to avoid issues with married segments. In your example - search ORD-NRT, not ORD-ICN...
With expert mode turned on you will see that the words "fare class" are underlined - click that link to see a box open with the fare class buckets and look for R - it will show something like R2 - meaning that there are two seats in the fare class available.
