Description
We report the measurements of branching fractions and direct $CP$
asymmetries
for neutral $B$ meson decays to the $hh$ final states, where $h$ stands
for
a pion or a kaon. We also study the charged $B$ meson decays into one
charged and one neutral kaon or pion.
We present improved measurements of the branching fraction and the $CP$
asymmetry of $B\to\eta h$. Here $h$ denotes $\pi^{\pm}$, $K^{\pm}$ or
$K^0_S$, and the $\eta$ is reconstructed through the decay channels
$\eta\to\gamma\gamma$ and $\eta\to\pi^+\pi^-\pi^0$.
We report the results of a search for the charmless hadronic decay
$B^+ \to \omega\rho^+$.
These analyses are performed using the large data sample
collected with the Belle detector near the
$\Upsilon(4S)$ resonance at the KEKB asymmetric $e^+e^-$ collider.
