Omikuji (consult an oracle)

Really it's like a fortune cookie. You buy one and open it to read whatever it says.

Usually there are five ranks; Dai-kichi (excellent luck), Chu-kichi (good luck), Sho-kichi (ok luck), Kichi (not too bad), and Kyo (no luck).

After you read it, you knot the fortune paper together on a tree branch or shelf (picture).
