  We present near-infrared spectra of late phase (>200 d) Type Ia supernovae
(SNe Ia) taken at the Subaru telescope. The [Fe II] line of SN 2003hv shows a
clear flat-topped feature, while that of SN 2005W show less prominent flatness.
In addition, a large shift in their line center, varying from -3000 to 1000
(km/s) with respect to the host galaxies, is seen. Such a shift suggests the
occurrence of an off-center, non-spherical explosion in the central region, and
provides important, new constraints on the explosion models of SNe Ia.
