An unknown man has sent about $910,000 to the municipal authorities of Eichime Prefecture in western Japan.

On January 29, a package arrived at the address of the governor of the prefecture of Echime Tokihiro Nakamura. In a cardboard box were packages of 10,000 yen notes.

In a letter in the box, an unknown sender asked to use the money for good deeds. He wrote that the name and address indicated on the mail are fictional and he wishes to remain unknown.

Governor Nakamura said on Thursday he welcomed such a donation. According to him, this money may be someone’s savings for a lifetime.

The governor added that the prefecture would consider using the money to support childcare and restoration work in areas affected by last year’s heavy rains.
