The Superior Court of Lima sentenced a Peruvian man to eight years in prison Wednesday for the 2001 slaying of a Japanese man in Gunma Prefecture.

It is the first time the country's judicial authorities have punished a Peruvian citizen at the request of the Japanese government. Peru and Japan do not have an extradition treaty.

Ricardo Moises Diaz Sanchez, 43, stabbed to death Tadao Kimura, 69, at a park in Ota, Gunma Prefecture, on Oct. 14, 2001, according to the court.

He was deported to Peru from Japan for staying illegally in 2004.

As Japan and Peru have not concluded an extradition treaty, Tokyo in 2007 called on Santiago to try the defendant under Peruvian law.

Sanchez, who had been on the run, was caught in Lima in July and remanded to custody.

In the court proceedings, Sanchez confessed to the killing and offered an apology.

He was also fined 30,000 sols, or around ¥900,000.
