We are investigating the physical conditions and the life cycle of interstellar matter and dust in our Galaxy and galaxies based on infrared observations with space projects, such as the Infrared Telescope in Space (IRTS)AKARI, ESA's Infrared Space Observatory (ISO), NASA's satellite Spitzer Space Telescope, and ESA's Herschel Space Observatory.  The IRTS is the first Japanese infrared space project in 1995 and AKARI is the first Japanese satellite dedicated for infrared astronomy launched in 2006.   These investigations revealed the ubiquitous presence of aromatic matter in space for the first time and provided key information on their processing in space.  We have developed mid-infrared instruments on board the IRTS and AKARI,  and contributed to the cryogenic telescope development and its ground test.  We are also making a complementary study of the dust properties with the COMICS on the Subaru telescope.
