The KamLAND experiment is a long baseline experiment, designed to explore the neutrino oscillation of e's from reactors, at a flux-weighted average distance of 180 km. The sensitivities to oscillation parameters are much improved with enhanced statistics of 2881 ton-yr data set, added data lowering the energy threshold, and suppressed systematic uncertainties. As a result, we firmly established the spectral distortion of reactor e's at > 5σ, and other hypotheses for neutrino disappearance, neutrino decay and decoherence, are strongly disfavored.
