The University of Tokyo), Bunkyo-ku, Tokyo, Japan, Here we briefly overview the latest data reduction toolkit and reduced images with it that are already available online. AKARI performed approximately 4000 pointed observations over 16 months in Phases 1 and 2, when the telescope and instruments were cooled by liquid helium. Observation targets include solar system objects, Galactic objects, local galaxies, and galaxies at cosmological distances. We describe major updates on calibration processes of near- and mid-infrared images taken by the InfraRed Camera, which has nine photometric filters covering 2-27 micrometers continuously. The latest toolkit has been applied to data from each pointed observation to generate calibrated and stacked images. About 90% of the stacked images have a position accuracy better than 1.5 arcsec. Uncertainties in aperture photometry estimated from a typical standard sky deviation of stacked images are a factor of approximately 2-4 smaller than those of AllWISE at similar wavelengths.
