The North Ecliptic Pole (NEP) field recently surveyed by Herschel/SPIRE is one of the legacy field of AKARI Infrared space telescope. We have carried out the study of ~300 SPIRE galaxies in this field detected at the 250-micron band, which have spectroscopic redshifts at the same time. These sample galaxies are matched/combined with the AKARI (continuous near- to mid-IR) data as well as ground-based optical/NIR data for the spectral energy distribution (SED) analysis. We've carried out SED-fit based on all available photometric data points to obtain various physical properties such as SFR, stellar mass, etc. We found that most of our sample are sub-mm counterparts of MIR-PAH galaxies, and majority of these galaxies appear to be luminous Infrared galaxies (LIRGs). They show a wide-spread distribution along the main sequence, indicating the sample consist of various types of star-forming (SF) galaxies in the redshift z<1. We will present the properties of these 250-micron selected dusty SF galaxies in the NEP field.
