We report the discovery of MOA-2013-BLG-220Lb, which has a super-Jupiter mass ratio q = 3.01 +/- 0.02 x 10(-3) relative to its host. The proper motion, mu = 12.5 +/- 1 mas yr(-1), is one of the highest for microlensing planets yet discovered, implying that it will be possible to separately resolve the host within similar to 7 yr. Two separate lines of evidence imply that the planet and host are in the Galactic disk. The planet could have been detected and characterized purely with follow-up data, which has important implications for microlensing surveys, both current and into the Large Synoptic Survey Telescope (LSST) era.
