One of the best known Japanese statues, the Daibutsu - Great Buddha of Kamakura is representing Amida Buddha and uses a mudrā called Mida jou-in. "Mida" is a shortened from Amida and "jou-in" is again a shortened from "zenjou-in", the Japanese name of the meditation mudrā. This is specific only to the sitting Amida Buddha statues, symbolizing the triumph of enlightenment over the world of illusions.
