The Japanese government knows the whereabouts of former Peruvian President Alberto Fujimori but has no plans to disclose it, Chief Cabinet Secretary Yasuo Fukuda said Friday.

Although Fujimori has contacted the government, "We cannot disclose the details for various reasons, including security," Fukuda told a regular news conference.

Tokyo has not received any request from Fujimori about his visa status in Japan, Fukuda added.

On Wednesday, Fujimori checked out of the Tokyo hotel where he had been staying, without publicly saying where he was headed.

Fujimori, a Japanese-Peruvian whose parents emigrated to Peru from Kumamoto Prefecture, submitted his resignation from Tokyo early Monday, following growing accusations of government corruption.

But Peru's Congress rejected it and instead declared him "morally unfit" for office and discharged him from his duties.

Meanwhile, the Foreign Ministry confirmed the same day that the Peruvian Ambassador to Japan, Victor Aritomi Shinto, relinquished his post as of Wednesday.

According to the letter that reached Foreign Minister Yohei Kono, Juan Aurich Montero, minister at the Peruvian embassy, will serve as acting ambassador.

Aritomi, also a Japanese-Peruvian, is Fujimori's brother-in-law and has served as Peru's envoy since February 1991, seven months after Fujimori assumed office.
