Amae (甘え): the Daijisen dictionary defines it as the feeling of counting on the goodwill of others. In 1971, the psychiatrist Doi Takeo published “Amae” no kōzō, The Structure of Amae. The book sold more than two million copies.
Doi defined the psychology of amae as an attempt to deny the fact of separation that belongs to human existence, and to overcome the pain of that separation.
