Keywords:lahar deposit, Fuji-Sagami River Mud Flow, Katsura River (Sagami River)
Detailed investigation of the lahar deposits in the upper reaches of the Katsura River and Shakunagare River located on northern margin of the Katsura River valley revealed that (i) the lahar deposit would bury the Katsura River valley entirely with more than 20 m thick, (ii) the deposit at upperstream area is characterized by frequent silt layers intercalation, and (iii) several debris flow deposit layers are transformed into hyperconcentrated flow deposit.
