For a better indication of which airlines fly to which cities I would suggest flightconnections.com over Wikipedia. The free version is sufficient for that query. Note that Taipei has 2 airports.
And, OP, if you are interested, don't forget the free stopover! When I made this trip I flew JL F to HND, spent a week in Tokyo, and then flew JL J on to TPE, all for 70k miles (one way -- the return was through different cities and is no longer bookable with AS miles)
