We have been developing a new neutrino detector named WAGASCI, to measure the cross section ratio of neutrino interaction with water and plastic targets at the J-PARC neutrino beamline. We use newly developed crosstalk suppression type Multi-Pixel Photon Counters (MPPCs) by Hamamatsu to detect the light emitted from scintillators in the WAGASCI detector. The new MPPC has an order of magnitude lower dark noise rate and crosstalk rate than previous MPPCs, and can be operated with higher over voltage, which results in higher photon detection efficiency (PDE). In order to realize a compact readout with a large number of channels, we developed an array of 32 MPPCs. A measurement system to test a large number of MPPCs is being developed.
