We measure the branching fractions for $B_s^0\rightarrow J/\psi \phi$ and $B_s^0\rightarrow J/\psi K_s^0$ decays using a \sim23.5 $fb^{-1}$ data sample collected on the $\Upsilon(5S)$ resonance by the Belle detector at the KEKB asymmetric energy $e^+e^-$ collider. The $J/\psi$ candidates are reconstructed from both $e^+e^-$ and $\mu^+\mu^-$ pairs; $\phi$ candidates are reconstructed from $K^+K^-$ pairs and $K_s^0$ candidates from $\pi^+\pi^-$ pairs.
