Fujimori has been in self-imposed exile in Japan since 2000

The government wants Mr Fujimori to face corruption charges in connection with an alleged irregular payment of $15m to the former Peruvian spy chief.

Mr Fujimori, who sought refuge in Japan four years ago after a corruption scandal, denies any wrongdoing.

He is a citizen of Japan, which bars the extradition of its citizens.

In February the Japanese foreign ministry appeared to rule out extradition.

'Corruption acts'

Peru made an initial request for Mr Fujimori's extradition in July 2003 to face a range of charges - including murder, kidnapping and inflicting grievous wounds.

The Peruvian embassy in Tokyo said the second request is to enable him to face charges of "corruption acts: forgery and embezzlement, in the proceedings related to the alleged use of public funds to pay a compensation of $15m to Vladimiro Montesinos".

The close aide of Mr Fujimori was sentenced in June to 15 years in jail for embezzlement, conspiracy and corruption - the fifth guilty verdict against him since he went on trial in 2002.

Peruvian prosecutors are seeking a 30-year jail sentence for its former leader, based on allegations stemming from his 1990-2000 rule.

But Mr Fujimori has said he is planning a political comeback in Peru, and hopes to run for the presidency in 2006.
