Description
Belle, a general-purpose detector operated at the KEKB electron-positron
B-factory at KEK, Japan, collected the world largest integrated luminosity
at the peak of the $\Upsilon(4S)$ meson as well as in a scan of the
center-of-mass energy range from 10.63 to 11.05 GeV.
We describe recent results on various bottomonium states studied -
mass and width measurements of the $\Upsilon(5S)$ and
$\Upsilon(6S)$ mesons, update of the $\eta_b(1S)$ and $h_b(1P)$ parameters,
new investigation of the exotic $Z_b(10610)$ and $Z_b(10650)$ states.
