At the top of the slope, a continuous pronounced outer ridge has developed that corresponds to the seaward boundary of the forearc basin, the “Kumano Basin”, which is filled with terrigenous sediments (Fig. 3; Moore et al., 2001). Beneath the landward slope in the Nankai Trough off Kumano and the Kumano Basin, an anomalous reflector running parallel to the seafloor known as the bottomsimulating reflector (BSR) has been observed (Kinoshita et al., 2009). This reflector has been recognized as a highvelocity layer of gas hydrate underlying low-velocity gasbearing sediments (Shipley et al., 1979). Indeed, the chemical and isotopic compositions of the pore waters imply the presence of gas hydrates in the sediments (Kinoshita et al., 2009).
