Savings Tied to Birth Weight

The service, known as "sukusuku bako," lets parents deposit money in amounts linked to their child's weight. An image referenced on the service's website shows a deposit figure of 25,000 associated with the program's top banner, indicating the scale of deposits tied to a child's weight.

The concept reflects a Japanese banking practice in which the amount a family deposits corresponds to the baby's body weight in kilograms — for example, depositing money matching the number of kilograms the newborn weighed at birth.

Growing Popularity Among New Parents

The program is promoted through its dedicated website, sukusukubako.jp, which presents the service as a way for families to mark a child's birth with a financial gift. The idea has drawn attention as an unconventional approach to encouraging early savings for children.

Details on eligibility conditions, interest rates, and participating institutions were not specified in the available materials.

A Savings Culture Built Around Milestones

Weight-linked deposits fit into a broader pattern of Japanese financial products designed around family milestones, giving new parents a structured way to start saving at the moment a child is born. The service's branding emphasizes a child's growth — "sukusuku" meaning to grow up healthy in Japanese.

The claim that a Japanese bank offers deposits matching a baby's body weight is True.
