We propose new survey for Active Galactic Nuclei using AKARI mid- infrared (MIR) all sky survey. The AGN selection in the mid-infrared can minimize wavelength-dependent selection effects. Using this sample, we can make the unbiased statistical studies that answer how much the space density of Seyfert 1 and Seyfert 2 is, what kind of galaxies the hosts of AGNs are and so on. The AKARI MIR all sky survey was carried out with two wide bands of the Infrared Camera (IRC) centered at 9 and 18 micron with the sensitivity of about 50 and 120 mJy (5-sigma per scan), respectively. The AKARI mid-infrared all-sky survey substantially improves the MIR data set of the IRAS survey of two decades ago. Our targets are selected with a criterion of F(9 micron)/F(K_S) >2 that culls AGN candidates from MIR all sky survey. In this semester, our 40 targets have been selected in the North Galactic Cap. We request four nights with KPNO 2.1m/Goldman Spectrograph for spectroscopic in order to measure their redshift and to confirm their activities.
