Japan hopes DPRK leader Kim Jong Il's death has no negative impact on Korean Peninsula security, and strengthens preparations for contingencies, Chief Cabinet Secretary Osamu Fujimura told an emergency news conference on Monday after Kim's death was reported.

Fujimura said Japan was aware of Kim's death through DPRK's TV broadcast and will keep an eye on next U.S.-DPRK contact.

Japan has already discussed DPRK leader Kim Jong Il's death with the U.S., South Korea, and Prime Minister Yoshihiko Noda urged officials to keep in touch with the U.S., China and South Korea over the issue, according to Fujimura.

Noda also urged officials to make full preparations for contingencies while defense officials have also been asked to be vigilant after Kim's death, said Fujimura.

Noda canceled a planned street speech at noon and returned to his office after Kim's death was reported. But Japan has so far no plan to change Noda's diplomatic schedule, said Fujimura.
