I'm making a ninja tool fan (tessen) and its name is:

Treasured Tessen of Onmyōdō

"Onmyōdō" is used in a way that's supposed to mean "The way of yin and yang" according to its Wikipedia article.

Would you mind translating this please, or if it's too much trouble, provide a good website where I can do it myself?

Thank you!
