Using the entire Belle data sample of $980\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of ${e}^{+}{e}^{\ensuremath{-}}$ collisions, we present the results of a study of excited ${\mathrm{\ensuremath{\Omega}}}_{c}$ charmed baryons in the decay mode ${\mathrm{\ensuremath{\Xi}}}_{c}^{+}{K}^{\ensuremath{-}}$. We show confirmation of four of the five narrow states reported by the LHCb Collaboration: the ${\mathrm{\ensuremath{\Omega}}}_{c}(3000)$, ${\mathrm{\ensuremath{\Omega}}}_{c}(3050)$, ${\mathrm{\ensuremath{\Omega}}}_{c}(3066)$, and ${\mathrm{\ensuremath{\Omega}}}_{c}(3090)$.
