Understanding infrared (IR) luminosity is fundamental to understanding the cosmic star formation history and AGN evolution.
In the AKARI NEP wide field, AKARI has obtained deep images in the mid-infrared (IR), covering 5.4 deg². However, our previous work was limited to the central area of 0.25 deg² due to the lack of deep optical coverage. To rectify the situation, we used the newly advent Subaru telescope's Hyper Suprime-Cam to obtain deep optical images over the entire 5.4 deg² of the AKARI NEP wide field. With this deep and wide optical data, we, for the first time, can use the entire AKARI NEP wide data to construct restframe 8μm, 12μm, and total infrared (TIR) luminosity functions (LFs) at 0.15
