   We propose systematic obsevations of a homogeneously-selected complete
   sample of luminous far-infrared objects. We selected NINE objects with
   L(FIR) > 10^12.5 L_solar from Strauss et al.'s 2Jy catalogue, TWO of
   which are the primary targets here while other FOUR of which have
   already observed with ASCA. This luminosity range is a natural
   extention of the FIR luminosity of luminous Seyfert galaxies to
   quasars. The results constrain (1) abundance and properties of type-2
   (obscured) quasars and (2) frequency of strong AGN activities among
   gas-rich, FIR luminous objects with intense starburst.
