How to draw an omikuji:

Drawing omikuji cost differs depending on the shrine or temple but usually costs around 100 yen. Sometimes the omikuji is a little strip of paper, and sometimes it comes with a gadget or figurine like this one, making it slightly more expensive.

Fancy omikuji

Sometimes you choose a stick and receive a paper omikuji corresponding to your choice. Other times, you can draw the omikuji directly from the box. After you read your omikuji, you can tie here in the temple.
