At Senbon Shakado temple in the Nishiijn district of Kyoto, there is a statue called "Okame Tuka".
Okame is the name of the wife of a carpenter who was in charge of this temple's construction. When the carpenter noticed that the size of the columns were wrong, Okame gave him a very clever advice so that the temple was safely completed.
Today, Okame is still referred to as a nice example of a good wife. It is said that her sweet smile gives you a benefit of a happy marriage. In Kyoto, Okame's mask is used as a decoration for framework completion ceremonies of constructions.
