We present J-band long-slit spectroscopic observation of NGC 1068 classifiedas a Seyfert 2 galaxy. J-band observations with OAO/ISLE provide cleardetection of spatially extended [Fe II]1.257um and [P II]1.188um lines. Wefound that [Fe II]1.257um/[P II]1.188um increases with distance from a centralcontinuum peak. Observed line ratios around the nucleus (continuum peak) areconsistent with a typical value expected from photoionization models, while theratios at 3" - 4" (210-280 pc) east and west of the nucleus are slightly higherthan this. In the off nucleus region of NGC 1068 we also found a possibleassociation between [Fe II]1.257um/[P II]1.188um and the radio continuum. Thissuggests a mild contribution of shock ionization induced by a radio jet outsidenucleus while photoionization by the central energy source is dominant near thenucleus.
