Abstract :
To carry out T2K, a next-generation long base-line neutrino oscillation experiment connecting 295 km from Tokai to Kamioka, is one of the main motivations to construct J-PARC. It employs 50 GeV proton synchrotron as a neutrino super-beam source, and Super-Kamiokande as a far neutrino detector. It can explore mass and mixing of neutrinos with unprecedented precision. It especially aims to observe tiny vmu-to-Ve appearance signal for the first time. A neutrino beam-line is under construction at Tokai campus, and beam commissioning is scheduled in April, 2009. In this talk I present characteristic features of the beam-line and apparatus therein. I also introduce beam-lines at the other facilities in J-PARC.
