I have done this before on an even shorter connection time. (About an hour and a half). It’s do-able. We had no check in luggage so we went to a faster line as I recall. Actually it was super quick but I think it was an outlier. 3 hours is plenty.
Edit: I double checked. I had exactly 2 hours and had time to spare. This was in March 2017 (ANA flight operated by United)
