Japanese Prime Minister Fumio Kishida on Monday said it is completely "unacceptable" for Japan to make a nuclear sharing deal with the United States, spurning the notion of Japan hosting U.S. nuclear weapons.

After a call by former Prime Minister Shinzo Abe a day earlier to discuss the option of nuclear sharing, Kishida said in parliament, "it is unacceptable given our country's stance of maintaining the three non-nuclear principles."

Japan has abided by its three principles of not producing, possessing or allowing nuclear arms on its territory, with the principles inspired by the devastating atomic bombings of the Japanese cities of Hiroshima and Nagasaki in World War II.

Kishida, whose constituency is in Hiroshima, is a proponent of non-nuclear proliferation and has vocally made his hope for a world free of nuclear weapons known.
