Just found your post and I'm glad I did before I booked. It seems like JL and KE have some sort of agreement in place? Using Google Flights and filtering Oneworld flights between TYO and ICN flights, KE shows up.
Slightly OT, if I don't get Avios/TPs, will I at least get Oneworld lounge access at ICN and NRT/HND?
