He initially denied his identity but later acknowledged it and was taken to an immigration detention center outside Tokyo. Kim would have found it difficult to enter Japan with a North Korean passport -- like most countries, Japan has no diplomatic relations with the communist state and doesn't routinely accept its passports. By some accounts, the diplomatic isolation has made the use of forged passports common among the few North Koreans who are allowed out of the country.
``He is known to be very interested in the Internet and high-tech industry, as well as the latest trends in advanced countries,'' he added.
The younger Kim is understood to have studied in Moscow and Geneva and to have lived abroad for many years. Kim Jong-nam's mother is believed to be the former actress Sung Hye-rim, although she and Kim Jong-il are never thought to have married, and separated many years ago. Kremlin officials have been quoted as saying she is living in Russia.
