We propose a search for the H-dibaryon in production from (,) reaction off nuclei by using a high-intensity beam at J-PARC with 100 times better statistics than KEK-E224 and E552 experiments. The Kurama spectrometer will measure the produced tracks at forward angle. We plan to construct a large-acceptance hyperon spectrometer with a Time Projection Chamber (hypTPC) to detect particles. It also enables to measure the weak-decay mode of the H-dibaryon, such as H-dibaryon decaying to and . We will present the Monte-Carlo simulation results.
