While J might be debatable, it appears to me that this product leaves ANA in the dust. F, PY, and Y are all more spacious and have more features than ANA's newest seats. And if the J seat is comfortable to sit in, that alone means JAL wins, since ANA's "The Room" cushioning is so hard that it doesn't even fulfill the basic function of a long haul airline seat, which is to provide a comfortable place to sit for long periods of time.
