*InfoNeeded* Japanese history: Magatama
 

If someone knows information about the Magatama prior to me posting this preach to your heart's contempt. Improving quality of like is something we all seek, and recently I learned about this, a 9-shaped figure with power that can change a life, however, I know it looks like the forming of an epicenter of energy but I have no leads on where the Japanese made this a big,yet,low-key symbol. Have a nice day!
