Well… yes… and no. By which we mean that, yes anyone can engage in shintô practices. However, shintô is definitly not a single monolithic whole, but rather it, and especially minzoku shintô, exists in countless variants, much like the yaoyorozu-no-kami.

So, sorry there is no one "right" version to be universal. One size does not fit all. Each location will develop it's own version.

All these different versions will be "right"… for that location and its people, and apply nowhere else.

And that's OKAY.

We don't expect everyone to engage in the same practices as we do. The local kami we enage with are part of our family, and we have a particular relationship with them.

For us, the only validation that matters, comes from them. You will have a different relationship with yours, and your validation should come from them, not us.
