Stories of the Japanese 00087 [Age of the Gods] The Transfer of the Land*

The trial of strength between Takemikazuchi and Takeminakata begins. You might get confused because their names are similar, so let's review. Takemikazuchi is the assassin sent by Amaterasu to take over Izumo. On the other hand, Takeminakata is the son of Okuninushi and is on the side trying to protect Izumo.
First, Takeminakata took Takemikazuchi's hand. Then, that hand instantly turned into an ice sword and attacked Takeminakata. Surprised by this, Takeminakata became afraid and began to flee.
This time, Takemikazuchi grabbed Takeminakata's hand, crushed it, and threw him far away. Thus, the trial of strength was decided in an instant.
Takemikazuchi chased after the fleeing Takeminakata. When he cornered him in Suwa, Shinano, and was about to kill him, Takeminakata began to beg for his life.
"Please do not kill me. From now on, I will not leave this land of Suwa. I will surrender the land of Ashihara no Nakatsukuni."
Can we really call this a "transfer of the land"? It seems more appropriate to call it an invasion through violence and intimidation rather than a transfer.
Takemikazuchi returned to Izumo and met with Okuninushi again. Okuninushi said,
"I will follow your orders and surrender this Ashihara no Nakatsukuni. However, please allow me to have a magnificent palace built that reaches up to Takamagahara, where I may live and be worshipped."
In other words, he is saying he will transfer the land on the condition that he himself be worshipped in a palace.
Thus, a palace was built to worship Okuninushi. This is Izumo Taisha in Izumo City, Shimane Prefecture.
The head priest of Izumo Taisha is called the "Izumo no Kuni no Miyatsuko," and its first generation is considered to be Amenohohi. Amenohohi is the second son whom Amaterasu first dispatched to conquer Izumo, the very god who was said to have "fawned over Okuninushi and failed to report back even after three years." In other words, Amenohohi, who was an assassin for Amaterasu's side, is worshipping the enemy leader, Okuninushi. It feels rather strange, doesn't it?
The current head priest is the 84th generation, Takamasa Senge (born 1943). The only families with family trees that continue from the Age of the Gods are the Imperial Family and the Senge family. The descendants of Amaterasu's eldest son, Amenooshihomimi, are the Imperial Family, and the descendants of the second son, Amenohohi, are the Senge family.
It is still fresh in our memory that Takamasa's eldest son, Kunimaro Senge (born 1973), married Princess Noriko of Takamado (born 1988), who is the great-granddaughter of Emperor Taisho.
Also, there is the "Crown Prince Gin-bura Incident," where the Emperor Emeritus, when he was a high school student, escaped from his security police and went for a walk in Ginza with his friends. One of the friends who accompanied him was Takahiko Senge (1933–2007), a member of the Senge family, so it seems the Imperial Family and the Senge family have a quite intimate relationship.
