Japanese Legend of Jesus

As you and I know, Jesus Christ was crucified, rose from the dead 3 days later and ascended into Heaven. However, that's not the case in Japanese folklore.
There is a 12 year gap that is not accounted for in the New Testament and the Japanese legend of Jesus fills this gap with a visit to Japan by the Lord to study Theology (the nature of God and religious belief). Upon returning to Judea at the age of 33, Jesus talked about his Japanese experience. The legend goes on to say that he was arrested by the Romans and was about to be crucified for heresy, he swapped places with Isukiri who is rather unrememberable and returned to Japan with one of his sibling's ears (despite being an only child outside of the legend) and a lock of hair from the Virgin Mary but not without a 6,000 mile long journey. The legend ends with Jesus spending his remaining days in exile with a family of his own under a new name and when he died, his remains were on display above ground for 4 years until he was interred under a mound of earth marked by a large timber cross surrounded by a picket fence in Shingo in the north of Japan's main island.
Unbelievable, we know! Despite this legend being very much false, it hasn't stopped the locals from running with the legend. In fact, Japan's main religions are Buddhism and Shintoism and only 1% identify as Christian.
