A combination of the production of Λ hypernuclei via hadron beams and their precision γ-ray spectroscopy using a Ge detector array, Hyperball/Hyperball2, has played essential roles in studies of hypernuclear structure. After a brief summary of our previous studies for p-shell hypernuclei at KEK-PS and BNL-AGS, we describe our plans of hypernuclear γ-ray spectroscopy experiments at J-PARC, in particular, the first experiment E13 starting in 2012, in which we further study ΛN interaction and measure Λ-spin-flip B(M1) values using light hypernuclei such as He Λ 4, Li Λ 7, B Λ 10, B Λ 11 and F Λ 19.
