X-ray spectroscopies are a powerful tool to study the AGN nuclear structure (< 10 pc), which is difficult to spatially
resolve. First, we report the results obtained by a systematic, broadband (0.5--150 keV) X-ray spectral analysis of
moderately obscured (Compton-thin; 22 <= log N_H < 24) AGNs observed with Suzaku and Swift/BAT (TK+16). Our sample
consists of 45 AGNs at z < 0.1 with log L_14-195 keV > 42 detected in the Swift/BAT 70-month survey, whose Suzaku
archival data are available as of 2015 December. All spectra are uniformly fit with a baseline model composed of an
absorbed cutoff power-law component, reflected emission accompanied by a narrow fluorescent iron-Kalpha line from
cold matter (torus), and scattered emission. Among some results, we mainly present that the [OIV] 25.89 um line to
X-ray luminosity ratio is significantly smaller in AGNs with lower soft X-ray scattering fractions. Thus, although
the [OIV] line is often used to estimate the AGN luminosity thanks to the less dust extinction and contamination from
the starformation, it may underestimate the intrinsic power of an AGN buried in a small opening-angle torus.

Additionally, we morphologically discuss the relation between the nucleus structure and ionized atomic line ([OIII])
emitter (TK+17, submitted). We performed NuSTAR and Gemini/GMOS observations of two local (z ~ 0.3) Lyman alpha blobs
(SDSS J0113 and SDSS J1155), which show largely extended (>~ 10 kpc) [OIII] line emission nebulae. Combined with the
Chandra data, the X-ray (0.5--30 keV) spectra of SDSS J0113 reveal a highly obscured (log N_H = 23.8) AGN with a low
scattering fraction (< 1%), thus likely buried in a torus with a narrow ionization cone. Our Gemini/GMOS 3D spectroscopy
proves its collimated bipolar outflows over 10 kpc, consistent with an idea that the torus may regulate the shape of the
ionized region. By contrast, SDSS J1155 hosts a weakly absorbed (log N_H = 22.8) and moderate scattering fraction (1.2%)
AGN that may ionize the gas over a wide solid angle. This is supported by the uniformly extended [OIII] emission observed
with Gemini/GMOS.
