Names of Mahatma Gandhi's three wise monkeys.

 Three Wise Monkeys

                Mizaru,    Mazaru,   Mikazaru,   

 [ these are English names in the same order as shown in picture ]

The three wise monkeys, sometimes called the three mystic apes, are a pictorial maxim. Together they embody the proverbial principle to "see no evil, hear no evil, speak no evil".
 

According to Japanese traditional belief the three monkeys are Mizaru, covering his eyes, who sees no evil;
Kikazaru, covering his ears, who hears no evil; and
Iwazaru, covering his mouth, who speaks no evil.
 

Sometimes there is a fourth monkey depicted with the three others; the last one, Shizaru, symbolizes the principle of "do no evil". He may be shown crossing his arms or covering his genitals.

 Four wise monkeys

There are various meanings ascribed to the monkeys and the proverb including associations with being of good mind, speech and action. In the Western world the phrase is often used to refer to those who deal with impropriety by turning a blind eye. 
In English, the monkeys' names are often given as Mizaru, Mikazaru, and Mazaru, but the last two names were corrupted from the Japanese originals.
