Any opup, when they rarely are needed, will go to JAL elite members first. LAX NRT zero change of that I'd say, NRT SIN could happen depending on the departure and day of the week.

JAL will only upgrade with miles or when they are overbooked, there are no curtesy upgrades.
Don’t forget the cash option: fare differences plus penalty
