The government has confirmed that deposed Peruvian President Alberto Fujimori, who is currently staying in Japan, has Japanese citizenship, government sources said Monday.

The sources said the government will announce the confirmation today.

The Peruvian government has demanded that Fujimori return to Peru and testify before a parliamentary commission investigating alleged slush funds controlled by Vladimiro Montesinos, the former Peruvian intelligence chief and one of Fujimori's close aides.
