We investigated the relative change in ion temperature (ΔTi/Ti), electron temperature (ΔTe/Te), pedestal stored energy (ΔWELM/Wped), and toroidal rotation velocity (Vt) due to type-I ELMs using diagnostics with fast temporal resolution in JT-60U. The increase in Vt was found in the direction of the plasma current right after the ELM. The recovery of Vt was found to be faster than that of Wdia, Te and Ti. It is also found that ΔTi/Ti can be larger than ΔTe/Te.
