The goal of the presented analysis is the measurement of the muon antineutrino single $\pi^{-}$ production interactions on CH ($\bar\nu_{\mu} + N \rightarrow \mu^{+} + \pi^{-} + X$) in the T2K off-axis near detector. This interaction mode is the second largest at T2K energies and studies are ongoing to include such events in T2K oscillation analysis which for $\bar\nu_{\mu}$ beam mode is currently limited to Charged Current (CC) quasi-elastic events. For this reason, a more detailed understanding of this interaction channel using near detector data is becoming increasingly vital. The measurement will be a double differential cross-section in muon kinematics and will be extracted using a binned likelihood fit. The event selection strategy developed for this analysis along with the validation studies performed to check the analysis robustness are discussed in this presentation.
