NH 101 shows 20 empty and 1 blocked J seats (out of 48) on 11/11 if that is the date. I'd say there is a good chance for you. But I would upfare to A and end up with a premium economy seat in case the upgrade to business fails. Maybe I am too risk-averse.
I have an A fare on that date ex-TYO and the equipment changed from 787-9 with 48 J seats to 787-8 with 32 J seats; only 9 available and I am still waitlisted with my PlusPoints. Nervous time.
