Ofuda

"An ofuda can be used by hanging in your house for protection. This type of household amulet or talisman had been issued by a Shinto shrine, and yep, it's made by inscribing the name of a kami (god) and the name of that shrine and/or of representative of that kami on either a strip of paper, wood, cloth oor metal. I placed it on my house like the rest of my village would do."
