My belief is that human myths spread based on wishful thinking. If enough people want to believe something, it will take on a life (or an afterlife) of its own.
For two millennia the farming village of Shingo claims to have protected a tradition that Jesus spent most of his life in Japan. The village is the home of Sajiro Sawaguchi, a man in his eighties who claims to be a direct descendant of Jesus and whose family has always owned the land in which it is said that Christ is buried.
Mr Sawaguchi emerged as Jesus?s heir only in 1935, when a priest in Ibaraki discovered a document in ancient Japanese purporting to be Christ?s will. This document supposedly identifies Shingo as the location of the tombs of Jesus and Isukiri. The claim is widely believed. About 40,000 Japanese visit the site every year. Two years ago it was presented with a plaque by Jerusalem, and next Sunday it will host the annual Christ festival of traditional Japanese dance.
According to the account in the Christ Museum next to the tombs, Christ arrived in Japan at the age of 21 and learnt Japanese before returning to Judaea 12 years later to engage in his mission and preach about the ?holy land of Japan?. The official Shingo history is that Jesus?s place on the Cross was ?casually? taken by his brother, leaving Christ free to return to Japan. On his return he fell in love with Miyuko, a local girl, and lived happily with his family among the rice fields until dying aged 106. – timesuk
