  We present the results of an unbiased asteroid survey in the mid-infrared
wavelength with the Infrared Camera (IRC) onboard the Japanese infrared
satellite AKARI. About 20% of the point source events recorded in the AKARI
All-Sky Survey observations are not used for the IRC Point Source Catalog
(IRC-PSC) in its production process because of the lack of multiple detection
by position. Asteroids, which are moving objects on the celestial sphere,
remain in these "residual events". We identify asteroids out of the residual
events by matching them with the positions of known asteroids. For the
identified asteroids, we calculate the size and albedo based on the Standard
Thermal Model. Finally we have a brand-new catalog of asteroids, named the
Asteroid Catalog Using Akari (AcuA), which contains 5,120 objects, about twice
as many as the IRAS asteroid catalog. The catalog objects comprise 4,953 main
belt asteroids, 58 near Earth asteroids, and 109 Jovian Trojan asteroids. The
catalog will be publicly available via the Internet.
