We theoretically show that the use of the hyperfine interaction together with a static electric field leads to ultrafast nuclear spin polarization. The idea is specifically applied to the isotopes of alkaline-earth atoms such as 27Mg (I = 1/2) and 37 Ca (I = 3/2), and we find that spin polarization as high as 88 % and 62 %, respectively, can be attained within the time scale of a few to tens of ns. This technique can be very effective not only for stable nuclei but also unstable nuclei.
