The dream liners are only a few years old. United has served SFO-KIX for at least 20, if not more, years. So it's physically impossible for it to always have been a Dreamliner route.
I flew a 744 on KIX - SFO in 2013, and it's alternated between that and a 777 over the years. Now it's a Dreamliner.

As for TPE, because it is a *A hub (not sure what kind of arrangements they have with EVA), perhaps it made sense? Imagine there is a decent amount of tech folks flying SFO-TPE as well, particularly from the manufacturing side...
