This page provides information about deep-seated landslides by the Ministry of Land, Infrastructure, Transport and Tourism. Deep-seated landslides are relatively large-scale slope failure phenomena where the slip surface occurs deeper than shallow landslides, causing collapse of both surface soil and deep ground. The page explains characteristics of deep-seated landslides and the ministry's initiatives, presenting historical cases including the Totsukawa disaster (1889), Arita River disaster (1953), Harihara River debris flow disaster (1997), and Mimi River natural dam disaster (2005). It also provides FAQs and links to related organizations.
