Ema in Diasho-in Temple, Miyajima, Japan.
Ema are wooden wishing plaques, used in a custom in Shinto shrines allover Japan. Worshippers write their prayers or wishes on them, then they are left hanging up around the shire. The kami (spirit or gods) are believed to receive them. Nowadays many types of pictures can be found on an Ema. Most common is the current year’s zodiac (2016 is the year of the monkey), or a god or spirit connected to the shrine.
