KamLAND is a 1000 ton liquid scintillator located underground in the Kamioka
zinc mine near Mozumi, Japan. KamLAND is capable of measuring the flux of
anti-neutrinos from nuclear reactors in Japan and Korea. I will discuss
evidence for anti-neutrino disappearance from the first 145 day run of the
experiment. In the context of two neutrino mixing the observations are
consistent with neutrino oscillations and the large mixing angle solution to
the "solar neutrino problem."
