It's the Tomb of Christ. Yes, that Christ, Jesus Christ. In the town of Shingo, Aomori, Japan there is a legend that in the missing years of Christ's life he came to Shingo to study religion. Then he returned to Judea for the events of the New Testament. When Christ was arrested his Japanese brother Ishikiri took his place on the cross and Christ returned to Japan. He then settled in Shingo, had a family, and died at 103 years old.
