You can get a start with ExpertFlyer. Do a timetable search for all flights departing TYO (which covers HND and NRT), then filter and select only AS flights. I see ten out of HND, to BKK (2x), SIN (2x), SGN, HKG, LAX (3x), and SFO, plus ten more out of NRT. I have no idea how comprehensive that is. I would assume each flight has a counterpart in the opposite direction.

(It is much easier to search for what you're asking for — AS-marketed, JL-operated flights — than to find all marketing airlines for a given AS-operated flight. But still hard to get a complete list.)
