Abstract　

The Infrared Astronomical Satellite 'AKARI' was launched in February 2006 and their observations have ended this year. I will make overview of the satellite and their instruments and present major scientific results, including solar system objects, interstellar material in our galaxies and external galaxies, active galaxies and AGN,survey of distant sources and cosmic infrared background radiation. All sky survey catalog of AKARI is available, which will be introduces, as well as current status of other catalogs under preparation. I will also discuss my interests in far-infrared astronomy and present results of far-infrared spectroscopic observation of Carina Nebula, especially the area around eta Carinae to understand the physical condition of interstellar material in massive star-forming regions.
