Searches for very high energy gamma rays from blazars with CANGAROO-III telescope in 2005-2009

► A partly new analysis was applied to CANGAROO-III data. ► No evidence of TeV gamma-ray emissions were found from four blazars. ► Non-simultaneous multiwavelength SEDs of blazars were modeled with a leptonic scenario successfully. ► The magnetic field of H 2356-309 might be lower than so far reported values. ► We find a consistency with the blazar sequence in terms of the magnetic field and the size of blob.
