A couple of years ago, heavy-ion based experiments (HypHI, STAR and ALICE) announced surprisingly short lifetime for ^3_Λ H mesonic weak decay (MWD), which is difficult to interpret given the fact that ^3_Λ His a very loosely bound system. It will be very interesting to study this issue with a different experimental approach. We propose a direct measurement for ^3_Λ Hhypernucleus MWD lifetime with ~10% resolution as J-PARC E73 experiment; ^4_Λ Hhypernucleus lifetime will also be measured as a feasibility test for our experimental approach. In this talk, I will introduce our experimental method and the current status of E73 experiment.
