Interesting, ARTESH

I also have come across this article -
"A Japanese woman who inherited the blood of Sassanid Persia"
In Japan, there is a woman who inherits the royal blood of the Sassanid Persia. Her name is Yuko Nishizawa.
Nishizawa, who is around 80 years old, claims that she is of royal blood in Sassanid Persia, based on her family register.
She reportedly said she was a 53rd generation descendant of Sassanid Persia.
She is very interested in her own roots and she seems to want to explore it somehow.
She then went to the Iranian Embassy in Japan to see if there were any Persian experts in Japan who could help her find her roots.
Mr. Rajabzadeh, a Persian professor at Osaka University of Foreign Studies, told the media about Mr. Nishizawa.
"There is no sure way to prove Ms. Nishizawa's claim. However, historically speaking, there is a good chance that her claim is correct."
Nishizawa, who is also a writer, is the author of a book called "Descendants of Persia."
Ms. Nishizawa wrote this historically romantic book based on her own ancestors.
Originally, the relationship and connection between Japan and Persia is very old, and it is said that the connection goes back to Japan's Asuka period.
Approximately 1,400 years ago, in order to show the world the Islamic powers of Arabia, they invaded the Persian Empire, which was a world power at the time.
The king of Persia at that time was Yazgerd III of the Sassanid Dynasty. Due to the sudden attack of the Islamic forces, the Persian army was unable to resist and was defeated.
At that time, many Persians fled the country. Among them were the princes and royal families of Sassanid Persia. And some of them are said to have come to China and even Japan.
Evidence of this remains in Nara's Shosoin as the treasure of ancient Japan.
It is also interesting to note that some events in Japan and Iran are similar.
There are many similarities between the chrysanthemum symbol mark of the imperial family and the marks left on the wall paintings of Persepolis.
Given the cultural similarities and historical connections, it is not easy to say that Mr. Nishizawa's claims are delusional. Moreover, she is making this claim with her own family register as evidence.
