A new solar neutron detector has been designed and has been set at Mt. Norikura Cosmic Ray Observatory since October 1990. The detector has successfully detected solar neutrons associated with large solar flares of June 4th and 6th 1991. Solar neutrons have been observed also by a traditional neutron monitor and a moon detector. The authors have compared the observed results obtained by the new neutron detector, the neutron monitor and the union detector and the response of each detector to solar neutrons has been discussed.
