So, Here is an Okinawan folk tale to get things started again.
The Gods Miruku and Sarka
The God Miruku appears as the god of a rich harvest in festivals that occur annually in the Ryukyu islands. Anything referring to the Miruku world means it is a prosperous society. The God Miruku on Okinawa is said to be the Miroku-bosatsu and the god Sarka is the Shaka, Buddha himself in the Buddhist religion. Although the story of the gods Miruku and Sarka is not widely known on mainland Japan, it does appear in mythology in South Korea as part of the earth's creation of the island of Saishu, just off Korea's south coast.
