This article delves into the often difficult decision for Japanese parents of when to stop pretending to be Santa for their children. It's a tradition kept alive with much dedication, mirroring that in western cultures. Parents grapple with the natural progression of their children’s skepticism and their wish to preserve their innocence. For some, the decision depends on the questions and doubts the children start to raise, while for others, it's a matter of age.

In Japan, the concept of Santa Claus and Christmas is taken from western cultures. Many Japanese parents enjoy dressing up as Santa or leaving gifts for their children in "his" name. However, in light of recent debates on child psychology and the emotional health of children, many are re-evaluating the tradition. The age at which to stop the Santa act becomes a hot topic among Japanese parents every holiday season.

In the U.S. or EU, this topic is similarly discussed among parents. While there isn't a universally accepted "right" age to reveal the truth about Santa, it's generally recognized that children will naturally become skeptical as they grow older. The emphasis is usually placed on maintaining the spirit of giving rather than the existence of the character.
