In brief
Japan is looking at adding an emergency exception to its Three Non‑Nuclear Principles in the upcoming National Security Strategy review. While a clause allowing nuclear weapons in crisis situations is the leading option, officials appear to favour keeping the principles unchanged. The strategy is due to be finalized by the end of the year.
Japan is debating whether to allow nuclear weapons on its soil in times of crisis as part of a review of its National Security Strategy that will be finished by year‑end.
The move would be a major shift from Japan’s Three Non‑Nuclear Principles, which say the country will not possess, produce or permit nuclear weapons. The new strategy, one of Japan’s three key security documents, already states that the core principles will remain unchanged.
Local media report that a proposal to add an emergency exception is the strongest option being discussed. The proposal would let the United States bring nuclear weapons to Japan if a serious threat arose, but would not change the day‑to‑day stance that Japan does not own such weapons.
Kyodo News, citing officials familiar with the matter, said the government is leaning toward keeping the existing principles unaltered even while considering the emergency clause.
The discussion comes amid rising regional tensions, with Japan’s security partners and neighbours watching closely. The decision could affect how Japan’s allies cooperate and how other countries view the balance of power in East Asia.
