In Japan, children are given money in special envelopes (otoshidama-bukuro or poti-bukuro) on New Year's Eve. The amount depends on the child's age and the relationship between the giver and the recipient. There are no strict rules, but there are general guidelines. For high school students, the amount ranges from approximately 5,000 to 10,000 yen. In large families, it is common to give equal amounts to all children to avoid any resentment. Parents often encourage their children to save a portion of the money for the future, promoting financial literacy.
