Following the IRAS observations, many main-sequence stars that have circumstellar debris disks have been discovered through their infrared excesses. Since debris disks are thought trace the final stages of planet formation, it is very important to statistically investigate the properties and evolution of debris disks. Observations at mid-infrared wavelengths are important for planet formation studies because mid-IR excesses trace the thermal emission from debris dust in their planet forming regions. We are carrying on an unbiased survey of debris disk candidates showing mid-infrared excesses by using the AKARI/IRC mid-infrared all-sky survey data. So far, we have identified 7 new debris disk candidates that show large 18 μm excess. Here, we present the initial results of the debris disk survey.
