‘Ushi no koku mairi’ means a visit to a shrine at dead of night to put a curse of death on somebody.
Ushi no koku means midnight from 1am to 3am. Mairi means visiting shrine.
If you would like to curse someone to death, you have to do like this.
You have to prepare strawman, peg and hummer.
And you have to go to shrine at between 1am to 3am and strike hard strawman that is portrayed as hateful person on tree using peg and hammer.
But you shouldn’t be seen someone during cursing. If you would be seen someone, this curse would lose effectiveness.
When you would do this for seven days in a row and climbing over sleeping black cow without fear, someone you want to kill will die in agony.
People say sleeping black cow would emerge on the way back on last day.
This is the Japanese traditional cursing method ‘Ushi no koku mairi’.
Kibune shrine at Kyoto in Japan is the most famous shrine for ‘Ushi no koku mairi’.
It’s because of ‘Kanna’.
Kanna is one of the Noh stories. Noh is Japanese traditional dramatic art. And ‘Ushi no koku mairi’ at Kibune shrine is in Kanna.
This is ‘Ema’.
Ema is a board illustrated horse. It is said that if you write your wish on Ema, the God make your wish come true.
So, you could see Ema written the word of curse mingle with Ema written the word of wish at Kibune shrine.
Also you could see strawman pegged on tree sometimes even now.
Do you have a person you want to curse?
