The Japanese government is discussing introducing an exception to its ban on bringing nuclear weapons into the country as part of its national security strategy.

Under the proposal being discussed, Japan could permit nuclear weapons to be brought onto its territory during emergencies. This would create an exception specifically to the last of Tokyo's three non-nuclear principles—not possessing, not producing, and not introducing nuclear weapons into the country. However, a general revision of the three non-nuclear principles is not being considered.
The Japanese government believes the move could enhance the effectiveness of the U.S. nuclear defense umbrella covering the country. The proposal aligns with a stance voiced in parliament in 2010 by then Foreign Minister Katsuya Okada.
At the time, Okada stated that in emergencies posing a threat to national security, the sitting government would need to decide whether to allow U.S. warships carrying nuclear weapons to enter Japan. His statement was seen as leaving open the possibility of a departure from the non-introduction principle.
Japanese authorities have repeatedly affirmed this approach by referencing Okada's stance over the years. Formally including the provision in national security documents is viewed as a step demonstrating the government's firmer commitment to this position.
If such a decision is adopted, criteria for bringing nuclear weapons into the country, as well as decision-making procedures between Japan and the United States, will need to be established.
Notably, Japan's three non-nuclear principles do not hold the force of law; they were initially established through a cabinet decision and later formalized by a parliamentary resolution.
Although Prime Minister Sanae Takaichi has repeatedly declared that her government adheres to these principles, she has refrained from committing to maintaining the same policy in the future. Prior to becoming prime minister, she suggested that revising the ban on introducing nuclear weapons could be considered to strengthen the nuclear component of the military alliance with the United States.
