Using Kepler data, we recently found evidence of occurrence of superflares on Sun-like stars with energy of 100 - 1000 times of the largest solar flares with frequency of once in 800 - 5000 years. These observations suggest that there is a possibility of superflares (with energy of ~ 10^34 erg) on the present Sun.
