Some of the things she noted are echoed by Dr. Martin Palmer in what he has noted on Nestorian Steele (as mentioned earlier):
A history book records that in 578 AD Mar Celghis , a Nestorian, and his family came from a “western land” to China and settled at Lintao, a about 500 km west of Changan. That is to say that Nestorians already came to China more before 600 AD. Professor Sakae Ikeda of Kyoto University, who is a Nestorian scholar and also a Hata family scholar writes a Nestorian named Mar Toma served Prince Shotoku at his side around 600 AD. Mar Toma means “Master Thomas” in Aramaic, and is the same name as Apostle Thomas. He was believed to be a leader of the Nestorians who came to Japan at the time of Prince Shotoku. So, Christianity was already in Japan at the time of Prince Shotoku. I believe it came to Japan earlier than this. There is a proof that leads us to believe it came no later than the fourth century. ....There are many myth associated with who Prince Shotuku really like. However, after several hundred years after Prince Shotoku passed away, adoration for Prince Shotoku swelled to bear many legends regarding him. And strangely enough, we see evidences of the stories of Nestorian amd the Anciient Christianity believed by the Hatas might have been appropriated into the legends of Prince Shotoku. Prince Shotoku is said to be the “Savior Bodhisattva” who was born in a stable. That is to say that he was a kind of savior. Prince Shotoku was called “Prince Umayado (Stable),” Umayado means a stable....It is normally considered derogatory to use a word such as “stable” in calling a person of noble birth and it should be avoided. However, the “Prince Umayado (Stable) was used as an honorific title. Dr. Kunitake Kume speculates that the Christian story that “Mary born Christ in a stable” was incorporated into Prince Shotoku’s legends. There are no one but two: Jesus and Prince Shotoku who were born in a stable among the saints in the world. That is not all. In fact the story of the birth of Prince Shotoku and that of the birth of Jesus Christ are in reality are very similar to the details of sequence of the stories. The author of “Buddhism and Nestorianism in the Japanese History,” Akinori Tomiyama, states as follows: “In mid .Heian era, at the time Michizane Sugahara was watching the moon in exile, there are evidences that intellectuals in Kyoto were reading the ‘Book of Luke’ (the Gospel according to Luke). It can be proven indirectly by ‘Legends and the Record of Prince Shotoku’ (917) which was believed to be written by Kanesuke Fujiwara. That is to say that there the birth story of Jesus, the ‘Book of Luke’ 1:26~2:21 is written exactly in the same sequence as the birth story of Prince Shotoku.” So, he describes it in details. Also, when you look at the legends concerning Prince Shotoku, we notice there are many other stories that remind us of the Biblical story. According to a legend, the “Savior Bodhisattva” appeared in the dream of Empress Kanjin, mother of Prince Shotoku, and prophesied the birth of Prince Shotoku. Similarly in the Bible, an archiangel Gabriel appeared in front of Mary and foretold the birth of Jesus. The other legend says that Saint Nichira, a Paekche, worshipped Prince Shotoku calling him the “Savior Bodhisattva.” But as it turned out, he was later assassinated. This indeed remind us of a story in the Bible that John the Baptist worshipped Jesus calling him the “Savior” but later he was assassinated.....
Masanori Tomiyama also writes as follows: In the “Book of Daigo ‘Legends and the Record of Prince Shotoku’ (13th Century) not only contains the resurrection story of Prince Shotoku, but the composition of the whole book appears to have copied after the “Book of John.” This gives a credence to the fact that an entire translation not an abridged version of the Bible might have been available in Japan.” That is to say that the story of resurrection of Christ in the “Gospel According to John” might had been incorporated into the legend of Prince Shotoku. Regarding the other legends of Prince Shotoku, he writes as follows: “For example, as something to remind us of the ‘Book of Matthew’ 25:34 and thereafter, there is a story of Prince giving the clothing and food to a starved at Mount Kataoka. Subsequent to the event, the starved man died and buried, but he resurrected several days later and only his clothing was said to be left on his coffin. This story from the ‘Chronicles of the Japan’ reminds us of the same vein of thought as the ‘Book of John’ 20:1~10.” Jesus taught us that if anyone gives food and clothing to a starved, he will be included in salvation; it is same as giving them to Christ himself. Also, the Bible says that when Christ died, buried, and after he resurrected only his clothing was left at his tomb. Prince Shotoku is also respected as the “founder of carpentry” and treated as the “protector of carpenters.” Among the carpenter there is even a “Guild of Prince.” Similarly, Jesus’ profession was carpenter. Shinran and Nestorian Philosophy As you can see legends about Prince Shotoku in later periods include many of those that were Christian origins. This is due to the fact that there were people who spread the story of Christ from the ancient times in Japan. Christianity came to Japan in early days of Japan. Its thinking was incorporated, or in protest to it, there were people who tried to make Prince Shotoku the Messiah. Perhaps, this was a reason behind the legend of Prince Shotoku among the people. Later, the founder of the True Pure Land sect of Buddhism, Shinran, made 115 hymns of Japanese translation of praise entitled, ‘Praise of the Great King Asan Prince Shotoku.’ Prince Shotoku who is recited there is the exact Japanese translation of ‘Legends and the Record of Prince Shotoku’ by Kanesuke Sugawara. “Christ”, who was hidden there, must have given great influence upon the faith formation of Shinran......
....Prince Shotoku built the [bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse]enno-ji (Four Devas) temple in Osaka. There was the welfare facility called “Shiko-in” attached to it. They are four institutions: “Seyaku-in” (pharmacy where free dispensation of medicine is available), “Ryobyo-in” (free hospital, clinic), “Hiden-in” (Sanctuary for those with no relatives), and “Keiden-in” (Sanctuary of religious, arts, and music studies). Prince Shotoku was the first one to begin the large scale social works, philanthropic, welfare works in Japan. Japanese Buddhist scholars praise Prince Shotoku for starting these philanthropic welfare works first in Japan that were heretofore not practiced by Buddhists in China nor in the Korean Peninsula in those days. However, these did not come from the Buddhist philosophy. Observing China and the Korean Peninsula of those days, their Buddhism was a guardian Buddhism for the state; it was far apart from salvation of individuals. You may think Mahayana Buddhism has the philosophy of “mercy.” But Buddhist scholars state that the philosophy of mercy was not implemented as a pragmatic work in ancient China nor in the Korean Peninsula. As it turned out that these facilities such as “Keiden-in,” “Seyaku-in,” “Ryobyo-in,” and “Hiden-in” are identical to those built by Nestorians all over the Silk Road. Nestorians built many facilities like these in Mongol and China. They worked unselfishly by building free schools, pharmacies, sanatoriums, orphanages, and hospitals ...They did not only preach the Gospel, but they also stressed philanthropic and welfare works. Due to their work, their Nestorianism penetrated into people early on.
....Why did Prince Shotoku carry on the works of the Nestorians in Japan? It is because there were Nestorians by the side of Prince Shotoku. And their advice influenced greatly Prince Shotoku. Professor Sakae Ikeda of Kyoto University writes that the first person who built an orphanage in Japan was a Nestorian named Raka. A Legend of Prince Shotoku: Borrowing from the story of Aaron’s staff [bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse]enno-ji, to which Prince Shotoku built “Keiden-in,” “Seyaku-in,” “Ryobyo-in,” and “Hiden-in” nearby, is now a Buddhist temple. However, this temple has a remarkable feature that cannot be seen at a normal temple. The entrance to this temple is no other than the great torii (gateway) of a Shinto shrine. Moreover, the torii was there since the time of Prince Shotoku. Though, it was made of wood at the time of Prince Shotoku not a present stone built. When I asked a Buddhist priest about the temple, he replied: “Once upon a time, since Prince Shotoku prayed to [bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse]enno before battles this temple was built.” But, there is “Tamatsukuri Inari (god of harvest) Shrine” immediately nearby. According to the shrine history, Prince Shotoku prayed not to [bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse]enno but to a god of the shrine. Here, too, we see an evidence of the Buddhist fabricating the history. [bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse]enno-ji temple used to be a Shinto shrine. Also, according to the shrine history of Tamatsukuri Inari Shrine, Prince Shotoku made a pilgrimage to the shrine before battles and prayed as follows: “If we are to win this battle, let a bud grow on this branch.” And he inserted a chestnut branch. Then, it is said that it sprouted a bud. That was a sign that a god was with him. This story, too, is very similar to the story of “a bud sprouted on the High Priest Aaron’s staff” of the Old Testament isn’t it? It was a sign that God was with Aaron. (Numbers 17: 5~8)Why did Prince Shotoku carry on the works of the Nestorians in Japan? It is because there were Nestorians by the side of Prince Shotoku.

....I stated that there were many Christians such as Nestorians, the Hatas (ancient Christians who came from the Central Aaia) around Prince Shotoku, and under their influence he started the philanthropic and welfare work. In the world, Prince Shotoku is generally considered as the “central figure of the Japanese Buddhism” and is responsible for spreading Buddhism in Japan. In conclusion, I believe it is mistaken. Prince Shotoku, in fact, had the same philosophy and religion (Christian Shintoism) as the Hatas. But Buddhism later became a kind of Japanese “national religion” and began to rule Japan autocratically. At that time, Prince Shotoku was given a new identity as the “central figure of Japanese Buddhism” and the “great contributor to Buddhism.” Firstly, the whole family and relatives of Prince Shotoku were murdered by Buddhists. Had Prince Shotoku been the central figure of Buddhism, why did Buddhists murder his whole family and relatives? Also, Prince Shotoku himself appears to be assassinated. Since Prince Shotoku, in those days, held the position next to the emperor, it was natural to spend several months of “mogari,” a ceremony for the repose of the soul. However, the record shows little or no period of “mogari” for Prince Shotoku. It appears that he was buried immediately. It was same in the case of Emperor Sushun who was murdered by Buddhists. He, too, was buried immediately without having a period of “mogari.” In order to appease a vengiful spirit, set himself up as a great person In those days, there was a belief system among the people that when an innocent was murdered he would become a “vengeful spirit.” So, it was necessary to quickly put the lid on the coffin and seal it. Also, in those days, there was a thought that the best way to appease the vengeful spirit was to set himself up as a great person. They thought if a person was thanked and adored as a great individual even a vengeful spirit would be appeased. So, for those who murdered Prince Shotoku, the quickest and easies way to protect themselves from the vengeful spirit was to set himself as a great person. That is to set Prince Shotoku as the “central figure of Japanese Buddhism” and the “great contributor to Buddhism” and have people venerate him. They thought that by doing so the vengeful spirit would be appeased and Buddhism would spread. For them it was two birds with one stone solution. I do not have enough space here to write about this in detail. I recommend for those who are interested to read the “Sealed Ancient History of Japanese and Jewish 2, Volume of Buddhism and Nestorianism."...
....Prince Shotoku went after his demise to “Tenju-koku” = heaven Back in 16th century, during the Azuchi Momoyama period, Ujisato Gamau (1556~95), the lord of Aizu, became Christian as a result of missionary work of Ukon Takayama. He was a Christian lord with the baptized name of Leo, but the Buddhist world of Aizu advertised his as an ardent Buddhist. When the Buddhist influence becomes strong, all the past great men become the great contributors to Buddhism. It has been repeated many times in Japanese history. So, we believe that Prince Shotoku’s case was no exception. After the demise of Prince Shotoku, an embroidery picture that depicts the “Tenju-koku” where the Prince went still exists at the Chugu-ji temple in Nara. This was embroidered by Kuma Hata who was commissioned by Princess Taratsume Tachibana thinking of the Prince. It is the picture called the “Tenju-koku Mandara (Mandala) Shuchomei.” If you look at it, it is obvious that the concept of Paradise other than Buddhism coexists. Masanori Tomiyama, who studied this aspect, writes, “I believe that the ’Tenju-koku Mandara Shuchomei’ undoubtedly means heaven of Jesus.” “’Tenju-koku’ where Prince Shotoku died and went to is the oldest concept of Paradise in Japan. This “Tenju-koku” or “Heaven” probably influenced the Pure Land concept of later Japanese Buddhism....
....Prince Shotoku himself was a man who must have 5 had a thought of this “Tenju-koku.” Also, there is a shrine called “Kamei-doh” at the [bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse]enno-ji temple built by Prince Shotoku. It existed since the time of Prince Shotoku. The faith that is practiced there is very similar to that of the faith of the Bethesda Pond (if you enter the pond while water is being stirred, you will be healed)....Prince Shotoku is a central figure who convinced many Japanese that “Japan is a Buddhist nation.” However, upon careful investigation, Prince Shotoku was more involved in Christianity rather than Buddhism. Later when Buddhism controlled Japan like the national religion, the real image of Prince Shotoku was buried forever. Then, he became the “central figure of Japanese Buddhism.” Nevertheless, we should find the truth in the important part of the Japanese history. Christianity is never a new religion that came recently to Japan or a western religion. It is the most precious faith that our ancestors also believed.
