Abstract	Recent advances in infrared observational instruments enable us to detect spectral information of young stellar objects (YSOs) in extragalaxies. Star-/planet-formation activities can occur in various kinds of galaxies which differ in size, shape, and environment. In order to understand the diversity of materials in the universe, it is very important to investigate how galactic characteristics affect the properties of materials around YSOs. We have been conducting an infrared observational study of YSOs in the Magellanic Clouds by using various telescopes such as the infrared satellite AKARI. The Large and Small Magellanic Clouds are the nearest irregular galaxies to the Milky Way and they possess low metallicity environment. In this presentation, I’m going to discuss the differences in the properties of circumstellar dust and ices around YSOs between the Magellanic Clouds and the Milky Way based on our recent observational results.
