The north ecliptic pole (NEP) field has been targeted long since it was surveyed by the AKARI space telescope with its unique wavelength coverage from the near- to mid-infrared (mid-IR).  Many follow-up observations have been carried out and made this field one of the most frequently observed areas with a variety of facilities, accumulating abundant panchromatic data from X-ray to radio wavelengths. In this talk, we report the current status: a release of a new band-merged catalog with the multi-band photometry for 91,861 AKARI sources over the NEPW field - all available data from GALEX UV to the sub-millimeter (sub-mm) bands (e.g., Herschel/SPIRE, JCMT/SCUBA-2).  Based on the deep optical survey with the Hyper Suprime-Cam (HSC) recently done over this NEP-Wide (NEPW) field, we identified faint sources (~20,000) in the near- and mid-IR bands, which improved the photometric redshift accuracy. This catalog motivates a variety of current researches and will be more useful when we ring in the new era of the NEP region, where the recently launched (eROSITA/ART-XC) and future space missions (such as JWST, Euclid, SPHEREx, and SPICA) are planning to take deep observations.
