One of the current most-demanded experiments in neutrino physics is to measure the last mixing angle theta13. KASKA is an experiment to detect new type of reactor neutrino oscillation and to measure sin2 2theta13 accurately using the world's most powerful nuclear reactor complex; Kashiwazaki-Kariwa nuclear power station. KASKA utilizes near and far detectors of identical structure at nearly optimized baselines and underground depths to cancel most of the systematics and reduce backgrounds. The expected sensitivity is sin2 2theta13~0.015, which is 10 times better sensitivity than the current upper limit measured by CHOOZ reactor experiment. Extension of KASKA project has potential to accurately measure other anti-nue oscillation parameters. Intense and precisely known neutrino flux measured by the KASKA-theta13 phase can be used to pin down sin2 2theta12 at a baseline ~50km and to measure Dm213 for the first time at a baseline ~5km. This Letter of Intent describes physics motivation, detector system and expected performance of the KASKA experiment.
