We crossmatch AKARI all-sky survey with the Sloan Digital Sky Survey Data Release 10 (SDSS DR10) and the Final Data Release of the Two-Degree Field Galaxy Redshift Survey (2dFGRS) and identify 118 Ultraluminous Infrared Galaxies (ULIRGs) and one Hyperluminous Infrared Galaxy (HLIRG). We find 40 new ULIRGs and one new HLIRG. ULIRGs in our sample are interacting galaxies or ongoing/post mergers. This is consistent with the fact that ULIRGs are major mergers of disk galaxies. We find that compared to local star forming SDSS galaxies of similar mass, local ULIRGs have lower oxygen abundances and this is consistent with the previous studies.
