  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.
