ASCA observations of the Seyfert 2 galaxy NGC 7582 revealed it was highlyvariable on the timescale of $\sim2\times10^4$ s in the hard X-ray (2-10 keV)band, while the soft X-ray (0.5-2 keV) flux remained constant during theobservations.  The spectral analysis suggests that this object is seen through an obscuringtorus with the thickness of N$_{\rm H}\sim1.0\times 10^{23}\rm cm^{-2}$. Thehard X-ray is an absorbed direct continuum from a hidden Seyfert 1 nucleus; thesoft X-ray is dominated by the scattered central continuum from an extendedspatial region. Thus we have an obscured/absorbed and a scattered view of thissource as expected from the unification model for Seyfert galaxies.  More interestingly, the inferred X-ray column was observed to increase by$\sim4\times10^{22} \rm cm^{-2}$ from 1994 to 1996, suggesting a ``patchy''torus structure, namely the torus might be composed of many individual clouds.The observed iron line feature near 6.4 keV with the equivalent width of 170 eVis also consistent with the picture of the transmission of nuclear X-raycontinuum through a non-uniform torus.Comment: 10 pages, 6 figures. To be appear in PASJ 50 No.5 (1998 Oct.25 issue
