How do I become a Japanese Shinto miko?

I'm Caucasian, but I want to move to Japan and become a Mikol. How do I do that?

by moving to japan and becoming a Mikol.

Travel to your nearest Shinto shrine & consult on how you may convert to their religion.

Depending on where you live, I would contact Rev. Barrish at the Tsubaki Grand Shrine of America in Washington state. You could consult with him regarding relocating to Japan and what would be necessary. Maybe you could spend some time at the shrine here in the States to see if that life agrees with you before making the big move to Japan.

It's hard to be Mikol even if you ware Japanese.
Because there are many Japanese who want to be Mikol .
But it's not impossible.
At first you have to learn Japanese.
Then you should ask in Japanese Answer.'checkupUri?'

But I don't suggest to do it. If you'll be miko ,you'll be poor.
