   Obscuration of central region of AGN by molecular torus is the essence
   of 'unified model' for radio-quiet AGNs. For radio-quiets, there is a
   good correlation between column densities (NH) derived from X-ray
   spectra and optical/NIR emission line width: small/large NH corresponds
   to type 1/2 objects. However, it is not yet clear whether the
   correlation is also seen in radio-loud AGNs. Although small/large NH
   are expected for broad/narrow line radio galaxies (BLRG/NLRG), under a
   simple extension of the 'unified scheme' from radio-quiet AGNs to
   radio-loud AGNs, some exceptions can be found in radio-loud AGNs.
   Therefore, we propose the observations of NLRG to test 'unified scheme
   for radio-loud AGNs' by examining whether all NLRG have large NH value.
