HEP experiments in Japan: The Next Generation

The HEP experiment in Japan is now stepping into next phase. J-PARC, which is a newly-built high intensity proton synchrotron facility, has started the operation recently. A new long-baseline neutrino experiment T2K is now at the commissioning stage utilizing the beam. In parallel, the upgrade of KEKB/Belle, a new generation B-factory experiment at KEK, is about to start. The accelerator will be upgraded to SuperKEKB whose luminosity is expected to be about 50 times higher. The detector is also upgraded to Belle II to keep up with the drastic increase. In this talk, a detailed review is given for these new experiments with some coverage of the readout and DAQ technologies.
