  Recent results of exotic states with heavy quarks, denoted as $XYZ$ states,
are presented. The results include searches for the $Y$(4260) in $B$ meson
decays, a spin partner of $Y$(4630), and the strange Pentaquark $P_s^+$. In
addition, the measurements of the absolute branching fraction of $X$(3872) and
search for double $Z_c$ production is discussed.
