One of the last wishes of executed mass murderer Norio Nagayama has helped to link Japanese kids who refuse to go to school with working children in Peru.

Four-time killer Nagayama, who became a well-known writer while behind bars, made a will before his execution in August 1997 at the age of 48 to set up a fund using his book royalties to aid poor children around the world, enabling a Peruvian girl to visit Tokyo three years after his death.

During her visit, Patricia Cruzado Munoz, a member of Mnnatsop, an association of some 10,000 working children in Peru aimed at improving their working conditions, talked about her organization's activities with members of Tokyo Shure, a free school for children who stay away from regular schools.
