I'm not sure where to post this, but since I'm looking for a word in Japanese, I figured I'd start here first.
I see sometimes (in movies and TV shows) how a flint and steel is held overhead to make sparks as a sort of blessing. I assume that this comes from Shinto or Shingon ritual, probably very ancient.
What's the name in Japanese for this practice? Is this term used commonly in Japanese to suggest blessings?
