On April 23, 2009, the first beam commissioning of the neutrino beam
line was started. At 19:09(JST), the first neutrino beam production is
confirmed by observing the muons by the muon monitor system installed
at the most downstream of the neutrino beam line of J-PARC.
The neutrino beam will be used to study nature of neutrino masses 
in the T2K experiment.
