Status of KASKA: The Japanese Reactor $\sin^22\theta_{13}$ Project

Abstract

Last year, in the NOON03 conference, we pointed out the importance of reactor $\sin^22\theta_{13}$ measurement and showed a realistic experimental idea to measure $\sin^22\theta_{13}$ precisely using world's most powerful reactor complex. Since then, the conceptual design of the experiment and negotiations with electric power company, have been progressing. In this proceedings for the NOON04 conference, the present status of the proposed experiment, now called KASKA, is described.
