  We performed a systematic X-ray study of eight nearby $\gamma$-ray bright
radio galaxies with {\em Suzaku} for understanding the origin of their X-ray
emissions. The {\em Suzaku} spectra for five of those have been presented
previously, while the remaining three (M\,87, PKS\,0625$-$354, and 3C\,78) are
presented here for the first time. Based on the Fe-K line strength, X-ray
variability, and X-ray power-law photon indices, and using additional
information on the [O III] line emission, we argue for a jet origin of the
observed X-ray emission in these three sources. We also analyzed five years of
{\em Fermi} Large Area Telescope (LAT) GeV gamma-ray data on PKS\,0625$-$354
and 3C\,78 to understand these sources within the blazar picture. We found
significant $\gamma$-ray variability in the former object. Overall, we note
that the {\em Suzaku} spectra for both PKS\,0625$-$354 and 3C\,78 are rather
soft, while the LAT spectra are unusually hard when compared with other
$\gamma$-ray detected low-power (FR\,I) radio galaxies. We demonstrate that the
constructed broad-band spectral energy distributions of PKS\,0625$-$354 and
3C\,78 are well described by a one-zone synchrotron/synchrotron self-Compton
model. The results of the modeling indicate lower bulk Lorentz factors compared
to those typically found in other BL Lac objects, but consistent with the
values inferred from modeling other LAT-detected FR\,I radio galaxies.
Interestingly, the modeling also implies very high peak ($\sim 10^{16}$\,Hz)
synchrotron frequencies in the two analyzed sources, contrary to
previously-suggested scenarios for FR I/BL Lac unification. We discuss the
implications of our findings in the context of the FR\,I/BL Lac unification
schemes.
