We present numerical studies of 3-dimensional electron magnetohydrodynamic (EMHD) turbulence. We investigate cascade timescale and anisotropy of freely decaying strong EMHD turbulence with zero electron skin depth. Cascade time scales with k-4/3. Our numerical results clearly show scale-dependent anisotropy. We discuss that the observed anisotropy is consistent with k\| ∝ k⊥1/3, where k\| and k⊥ are wave numbers parallel and perpendicular to (local) mean magnetic field, respectively.
