The recent updates of the North Ecliptic Pole deep (0.5~deg$^2$, NEP-Deep)
multi-wavelength survey covering from X-ray to radio-wave is presented. The
NEP-Deep provides us with several thousands of 15~$\mu$m or 18~$\mu$m selected
sample of galaxies, which is the largest sample ever made at this wavelengths.
A continuous filter coverage in the mid-infrared wavelength (7, 9, 11, 15, 18,
and 24~$\mu$m) is unique and vital to diagnose the contributions from
starbursts and AGNs in the galaxies out to $z$=2.The new goal of the project is
to resolve the nature of the cosmic star formation history at the violent epoch
(e.g. $z$=1--2), and to find a clue to understand its decline from $z$=1 to
present universe by utilizing the unique power of the multi-wavelength survey.
The progress in this context is briefly mentioned.
