We report preliminary results of AKARI observations of two globular clusters,NGC104 and NGC362. Imaging data covering areas of about 10x10 arcmin^2 centeredon the two clusters have been obtained with InfraRed Camera (IRC) at 2.4, 3.2,4.1, 7.0, 9.0, 11.0, 15.0, 18.0 and 24.0 mu. We used F11/F2 and F24/F7 fluxratios as diagnostics of circumstellar dust emission. Dust emissions are mainlydetected from variable stars obviously on the asymptotic giant branch, but somevariable stars that reside below the tip of the first-ascending giant branchalso show dust emissions. We found eight red sources with F24/F7 ratio greaterthan unity in NGC362. Six out of the eight have no 2MASS counterparts. However,we found no such source in NGC104.
