Mappo-shiso was a end-of-the-world theory that originated in China and considered the thousand years after Shaka's death as Shobo, Age of the Right Dharma, the next thousand years as Zobo (Age of the Semblance Dharma) and the next 10,000 years after the two thousand years as 'the latter days of Buddhism' (Mappo).
末法思想とは、釈迦入滅後千年を正法、次の千年を像法とし、計二千年を経過した次の一万年を末法とする終末論とも言える思想で、中国から伝播した。
