Experimental studies on the ωπ0 and νπ- systems in the π-p reactions have been performed at KEK. The moment analysis of the ωπ0 system shows a clear peak of b10(1235) in the IJpc = 11+- wave. In the 11-- wave, no clear peak is seen. The properties of C(1480) with 11-- and ρ{variant}(1450) are discussed taking into account upper limits of their cross sections. The experiment on the νπ- system was planned to search for an exotic resonance with IJpc = 11-+. The data taking run was finished and an analysis is under way.
