This is a traditional Japanese symbol consists of seven Hiragana characters : "?", "?", "?", "?", "?", "?", "?" (pronounced as "he", "no", "he", "no", "mo", "he", "ji"). In the Henohenomoheji symbol these characters are meaningless, but arranged to shape the human face. It's just like ASCII art.
Henohenomoheji free icon was designed by libberry for icons Png and presented to its users.
