• We have carried out the hyperon photo-production experiment at Eγ=1.5-2.4 GeV to study the properties of Λ^*(1405) hyperon through the lineshapes in terms of the π^+*^- andπ^-*^+ decay channels. To obtain clear event samples of Λ^*(1405), a Time Projection Chamber (TPC) has been constructed as a 4π detector. Since the mass ofΛ^*(1405) lies close to the *^*(1385), the estimation of the *^*(1385) contamination to the Λ^*(1405) invariant mass spectrum is important. We report the status of analysis of the Λ^*(1405) ineshape with an emphasis on the study of the contamination from the nearby resonance *^*(1385).
