I present recent results on comparison between gamma ray SNRs and the interacting neutral clouds. I shall discuss on SNRs including RX J1713.7-3946, W28, W44 and RX J0852.0-4622 with an emphasis on the role of dense atomic and molecular gas in the interaction. In RX J1713.7-3946, I shall present highly clumped distribution of dense gas which exhibits good correlation with gamma rays and X rays on a pc scale and argue that cosmic ray acceleration is enhanced around dense gas, leading to production of these high energy radiations. I interpret that such enhanced CRs are due to the highly turbulent state caused by the shock interaction with the dense clumps as suggested by recent MHD numerical simulations (Inoue, Yamazaki, & Inutsuka 2009)
