J IKK depends on R space, not revenue fare buckets. So it is definitely not any unsold J seat.
For Y IKK, it's supposedly any unsold seat in Y; however, AC may be willing to oversell flights, so there may still be tickets for sale even though IKK is not available.
I believe this can even lead to some instances where fixed mileage rewards aren't available (even IKK) but market fare are, since market fare rewards come from revenue buckets.
