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.
Shingō village is the location of what is purported to be the last resting place of Jesus, located in the "Tomb of Jesus" (Kirisuto no haka), and the residence of Jesus' last descendants, the family of Sajiro Sawaguchi. According to the Sawaguchi family's claims, Jesus Christ did not die on the cross at Golgotha. Instead his brother, Isukiri, took his place on the cross, while Jesus fled across Siberia to Mutsu Province, in northern Japan. Once in Japan, he became a rice farmer, married, and raised a family with three daughters near what is now Shingō. While in Japan, it is asserted that he traveled, learned, and eventually died at the age of 106. His body was exposed on a hilltop for four years. According to the customs of the time, Jesus' bones were collected, bundled, and buried in the mound purported to be the grave of Jesus Christ.
The sleepy village of Shingo in Aomori Prefecture, Japan, is home to a conspiracy theory that rivals the revelations of “The Da Vinci Code”. Every year in June, a unique ceremony awakens Shingo, once known as “Herai”. The ceremony consists of women in kimono dancing around the grave of Jesus Christ. Yes, THE Jesus Christ. You didn’t know that you can visit his grave in a beautiful park in Japan?
Jesus traveled to Japan when he was a youth and learned Japanese ways and customs. He later returned to Israel in his 30's where his teaching was rejected. Before the Romans could crucify him, his identical twin brother Isukiri snuk in and "casually took his place on the cross" [so says the sign at the location]. Afterwards, Jesus returned to Japan and spent his life in Shingo as a rice farmer. He lived until 106, raising a family and doing good deeds locally. He was buried in the Shingo village where a mound with a cross marks his grave.
