In a show of holiday generosity, a person identifying themselves only as Harry Potter’s headmaster, Albus Dumbledore, left a special surprise for a daycare center north of Tokyo.

The surprise was ten thousand dollars in cash, found in an envelope placed in the center’s mailbox.

With the money was a letter signed “Albus Percival Wulfric Brian Dumbledore,” and instructions to use the money to make the center more enjoyable for the children.

The school is considering using the windfall to make repairs on their aging building and to buy new toys.
